*Good* Class 6 MicroSD cards - G1 Q&A, Help & Troubleshooting

Hey guys,
I've been having a great deal of trouble with my cheap Transcend 8gb class 6 card . . . spontaneous unmounts, lots of finicky behavior all around. Having the apps on the SD means the phone crashes, and the app permissions get borked to hell.
I've heard these are not very good cards (you get what you pay for in this case) and are known to have problems with the G1 . . . or the G1 is known to have problems with them. Either way, perhaps some of you can help me:
-Are the Transcends indeed "problem cards?"
-Has anyone had one, gotten fed up with the crashing, replaced it, and is in good working order?
-If that's the case, what are some known good cards I can get to replace it?
Thanks!

they are not problematic, they are just not compatible enough! Every device has issues with every other sd card no matter what. I been buying sd cards and I have had problems with these since the day they were born.
In my opinion, transcend are one of the more compatible sd cards. Funny thing is I use a sandisk on my phone and I always had issues with sandisks before on other devices.

First things first, Transcend are by no means a 'cheap brand'. They actually make some of the more expensive memory cards you can buy, and they are very good. My memory card is a Transcend, an 8GB Class 6 like yours.
The difference is that my one has never failed me. It's actually very fast. Furthermore, Transcend are known for making good memory cards. Maybe you just got unlucky with your one.

I ordered the A-Data class 6 to replace my class 4 sandisk based off raving reviews. I havent read much for negative reviews on the A-Data lineup, even though they are a smaller company

I had a transcend 8gb class 6 card that failed completely (can't even access from a PC). When it failed, and due to my apps to sc and other changes, my phone wouldn't boot without a card. I had to install the 128 mb card once I got home and re-update from scratch. When the transcend card worked, it was fast. I've used other cards of theirs in my cameras for a while now, and they've been very good. But this failure caused a bit of a headache for me. I'm at the point where if I see any problems with my sd card, I'll simply replace it to avoid worse problems. Wouldn't have helped in this case as I saw no signs before hand. If it means much, I'd try another transcend card again.

Sorry, didn't mean to bash Transcend undeservedly. So maybe it's just an issue particular to their cards and the G1?

Thread moved to Dream Q&A, please post in the correct place; not dev related.

i went through 2 4gb class 6 adata cards that wouldn't work at all after i partitioned them. phone would bootloop regardless of rom. it worked great if i left all fat32....very strange.

orange that should be a good card. if you have any way to put it into your computer and try to format it, via a usb conector ect. then give that a go. other wise it could be the rom your on, what type of rom are you using or is it stock?

Don't base your purchase decision on the Class classification. Sandisk's Class 2 cards have known to have stellar performances under ATTO.

Cyanogen Mod. Latest (4.2.12.2) but I've had this problem in previous versions. A friend's G1 has experienced similar problems with the same Transcend 8gb card, and I vaguely recall hearing warnings against using that brand w/ the G1, but perhaps I'm mistaken.
For now, I've deleted the EXT and swap partitions from the card and did a wipe so that all apps are running from internal memory. I haven't noticed any unmounts today, but last night the phone was unusable and this same sort of thing has happened before with the same card in both my original G1, and the warranty replacement (the warranty replacement was for an unrelated issue).

2i KILLING SD cards??!!

Hi,
Please note that I know there is a thread at the top about SD card issues, but this post is not about locking up, this post is about 2i killing SD cards, thanks.
I have had my XDA 2i for about 3 months. When I first bought it, I bought a Viking 1GB SD card to use with it. After a month or so, the SD card died. At that time I thought I had a faulty SD card, so I bought another Viking 512MB SD card.
To my horror, it died as well today.
Can't read the cards in any of my readers.
So question is - do I have a faulty 2i? Is it a common problem at all? Or is there a design problem with 2i? Or is the 2i not compatible with Viking SD cards?
It seems like people have great success with the Transcent cards regarding the lock-up issue. So does anyone know whether it is going to solve this "murdering" problem?
Many thanks,
Wayne
I'm sure i have seen this type of post before...but to be honnest i think it might be an isolated case, perhpas its only that brand of card the XDAIIi will "Kill"
Its more than likely that what causes your XDA to kill the Viking SD cards is the same thing that only causes other SD cards to freeze.
So perhaps Viking cards are more sensative to the XDAIIi (pain in the ass) problem.
Hmm... i've had 3 SD cards die on me recently too (a PQI 1GB, a Sandisk 256MB and a Pretec 128MB)... i thought it was just a bizaare coincidence or something but now you come to mention it... :?
I've also had two viking 1gb cards die on me each within a few days of receiving them!!!! I now use a Sandisk Ultra II 2gb card which works great apart from TomTom locking up if I don't turn of the phone radio stack.
I bought a 1gb Viking Card from Ebuyer and after about 2/3 months it dided Just got my replacement so finges crossed
I've had a similar problem with my IIi I went through 2 512Mb unbranded cards from mymemory.co.uk in the space of 3 weeks. The first when screwy and reconfigured itself to be a 30Mb card. The second was completly unreadable. I put it down to me being a cheap-scate and buying unbranded products. :wink:
For the past six months I have been running without an SD related hitch (touch wood) using a Sandisk 1Gb Ultra II.
Same here.
The thing is that my 1Gb Viking card only lasted 4 days!!!!
:? :? :?
I want to get another kind of card but i´m no sure what´s the best one out there.
I think I am gonna give Transcend a go...
Viking is definitely a no-no.
Really shouldn't have just gone for the cheapest
Most SD cards have long warranty periods. Get on to either the manufacturer or the retailer and get them replaced. I once had a Sandisk card die on me and it was replaced straight away. Its replacement is still working in my digital camera now.
i too had a kingston totally die on me ,and at the same time i dropped my pda and it went skidding along the foor and was bust ,so i went back to o2 and told a small lie and so got a new 1 as it was only a week old at the time so i never found out if it was the pda or sd card ,i have now had the same sd card for a few months now no problem ...it's a transend
Those SD Card from Viking and Kingston are known faulty with XDA...
I never buy these brands of SD Card..
Try KingMax If U like, it works perfect with mine xda2 and xda2i
I had my 512 Mb Kingston SD card killed with my Alpine too
This is not a city-myth for me anymore..
Hmm... Did not heard something about broking A-Data's card. Now using one 150x 2Gb. No problems at all.
Killing SD cards
Hi
Yep same here 4 cards have been murdered by my XDA11i, a sandisk 256 and a couple of lesser sizes, all worked in my inbuilt laptop card reader till they went in the XDA. Now all i get is this card is write protected and its NOT!..Worse of all it also kills RS MMC out of my nokia 6680 so beware. These cards came brand new and played perfectly in the laptop then a couple of sessions in the XDA and bang This disk is write protected, they will be written to when in the nokia and synced by usb cable but the laptop will not write to them at all..
Getting dissapointed with the XDA11i doing this and constantly freezing looking like time to offload on ebay
Dave
OK MY Replacement Viking from Ebuyer has just died so, The Vkiings are not good for the XDA then.
hi,i popped in here after a freind pointed this out to me.
I have spent the last 3 mths checking out suppliers of sd memory for resale thru my business and most of the brands mentioned here are the ones ive come accross.
however whats not on the packet when you buy these wonders of technology is that they are modified from Rejects off the lines.
they are also modified from 128/256/512 low quality chips.
this means that compression routines have been applied to them to produce a fake formating size.
i found,purely by accident,that if you stick your sd card in a palm pda,it will read off the original manufacturers code which looks like this 0128********,0256*********,0512********* and tru 1 gig are 0000********.i personally have only just(after 3 mths)managed to secure a shipment that has been tested to be true 1 gig.thank god.
just thought this mite help you.
my sandisk died too
Bought a 1G sandisk card and ive only had it for 3months and all im getting with the 2i is a freezing screen.I soft reset at least 10 -20 times a day.Im begining to wonder if something is wrong with the 2i.Sometime the only way to start up normally is removing the card .Can someone please advice me which 1G card works best with 2i.I ve heard the transend work ok..Thanks
3 Solutions for SD cards that don't work anymore in a PDA !
1/ Try to format with your pc or other card reader (like in pc or printer).
2/ Try to format it with PocketMechanic (dowload the free trial)
There are many options : format logical, ntfs, fat, for digital
camera,pda,...
With this tool I could reformat the card and use it again
3/ Buy a Kingston Elite Pro card in future or other with LIFETIME WARANTY
I once had a card that couldn't be fixed from Kingston, it had LIFETIME
waranty! Yess KINGSTON ELITE PRO series offer that. I just posted it
internationally to London's office with RMA nr, and received a NEW SD
Card in plastic! Speaking of service!
Bought this card from an Ebay shop. I don't know how the service is
with other brands, but some have 5y waranty, you can try to return it.
Hope helping ya all!
XDAIIi still is the best, now an XDAIIi with build in GPS Antenna and we have a real all in solution
My XDAIIi might have killed Kingston 512 SD card
hi
I have a XDAIIi purchased about 4months ago.
My XDA IIi is having a lot of problems and it also may have killed my 2 months old kingston 512 MB SD card...
I tried some data recovery softwares but they did not help.
So I brought the damaged SD card to data resucue service but they could not fix data structure of SD card.... saying as below.
I have tested your SD Memory card. The card is certainly faulty. It’s a hardware fault with the memory unit. As s solid state memory ship there is no way to repair this. After further investigation, it appears this problem is very common and reports of the same brand sd card have also been reported on the internet.
I’m sorry but we have no way to extract the data off a faulty SD card like this. The size of the car is defaulting to the factory setting of 2 TB (which is HUGE!!) and other software reports it as a RAW card at 0mb.
Normally if for example the card has been accidentally formatted or the file system has been corrupted we could have easily recover the data but in this case of a hardware fault we have no method to help you. We have tried everything for you. As I told you, it was worth trying. There is no charge to you.

Hi
Mine froze up repeatable until I found this site and removed my 128 ULTIMA. I then removed my PANASONIC 256 “Hi Speed” (supposedly but does not say what speed on the card) from my camera and all is good so far.:shock:

Max Memory Card size?

Anyone know the maximum card size the kaiser/vario3 supports?
I am thinking about getting a 6Gb microSDHC
Got a 6Gb in since Saturday. Works a treat.
32gb max even though it is not available yet.
Essentially, ANY SDHC card available as of today will work in the Kaiser.
Sweet, god this fone roxs, so pleased i didnt get the limited iphone!
I asked HTC about this when I first bought my Kaiser. They told me it would support up to a 4GB micro SDHC. There have been other posts with people who have successfully installed a 6GB card but have found problems when trying to access files and the phone has locked up, so beware.
8G
I have a Sandisk 8Gig in mine... works perfectly.

I think most of that has to do with crappy quality SD cards.
I've never had a problem with any Sandisk card I've had. 1,2, and 4 GB
The reason for HTCs ascertion is simple. At the time of production of the Kaiser the largest SDHC microSD card available was a 4GB card. Therefore, they could only certify that it worked with 4GB cards at that time. And, as far as persons having issues with their phones locking up while trying to read from a 6GB card, I would venture that no matter which card that person(s) was using they would have experinced a similar fate due to whatever it was they were doing at the time.
That said, I have no reason to believe that SDHC cards up to 32 GB will not be fully supported by the WM6 OSes currently being distributed. Furthermore, I anticipate that future revisions of said OSes will equally compatible.
Hi guys,
Sorry to re-hash this thread, just wondering...
I'm about to buy a TyTN II off a friend in work, and wondering if someone could advise me the best card to buy?
I'm a massive music buff, and love my current hermes, however 8GB isn't enough these days, and itching to have more music to beat the iMoan.
So far, some digging has found me this: http://www.ebuyer.com/product/155755
Would that be suitable for the TyTN II?
Thank you,
I currently have a 8GB Class-4 sandisk card in my Kaiser and it has worked perfectly since I installed it last year. I have some TomTom maps and a load of music and its about 2/3's full. I have been looking for a 16GB but have held off so far. 7Dayshop.com have some 16GB MicroSD cards starting at £32.99 delivered, but these are only Class-2.

According to the information I have, the 8925/Kaiser/Tilt, etc, will support at 32gig microSD card.
From what I've read, the Tilt/Kaiser will support up to a 32 gb, although 16 gb is the largest out.
However, I also read that it will only read at Class 2 speeds. Anyone know if that's actually true? If going to class 6 will give me more speed, I'd definitely go for that when I upgrade my card, but if not, there's no reason to pay more for it.
Anyone know when the 32 gb cards are supposed to come out?
Always buy a Name Brand Card and From a Reputable Dealer and you won't have any problems.
There are a lot of nefarious people out there that trick 2GB cards to act like 8GB cards and by the time you find out, because of locking up and data corruption they are gone with your cash. Don't cheap out when it comes to your data.

[Q] 32gb micro sd freezes phone once inserted

Its been a week since Ive been desperately searching with no luck!!!!!!!
I just baought a kingston 32gb class 6 micro sdhc but when ever i put it in my hd2 it just freezes up and as soon as I remove the card it works fine again.At first i though that it was a fake so I:
1)performed multiple tests,
2)reformated a 1000 times,
3)even putting 20gb of data just to make sure.
Turns out that it is authentic and it works perfectly on my girlfriend's htc BalckStone it also worked when I installed NAND (which i later removed due to insufficient memory).Ive been searching for weeks, I think its a windows mobile issue, any tips??
HD2 freezing with microsd
I have the exact same problem.
HD2 + 32Gb Kingston micro SD card (bought from ebay)
Freezes on card insertion. Unfreezes when card is removed.
Found any solution?
Do a google search for SD Formatter.
Try reformatting using that program.
Also, when you're reformatting, don't use the phone, use an external card reader or adapter.

If you ahve bought a 32GB SD card from ebay there is a very high probability that you have bought a FAKE 32 gb card.
If it was cheap its 100% a fake card.
These fake card are actually 1/2/4/8/16GB card but have been modded to report 32GB, some of them you can use but data will get corrupted as soon as you get near the real capacity. Some will just not work from the offset.
Stick your card into your pc via reader/adapter and run it through a drive scanning software and see if its got any bad sectors you will soon know if its fake or not.
The same issue with my 16gb microsdhc. On my friends Samsung Galaxy S it works, on microsd carder it works. But not on my HD2.
I had scanned my microsd with few scanners all of them shown that my SD is in perfect condition.
What about formating? What program should I use? And what formating options should be(file system and etc.)

This is an issue that has yet to be solved, unfortunately I cant get any real answer even after searching for weeks. My only solution now is just to buy a 16gb and use the 32gb for some other occasion.

Oh, yes it is. At least mostly true, if not even absolutely true.
I've been using a class 2 32 GB Sandisk micro SDHC card for a year now on my HD, and it will go into my Leo as soon as I get it. Absolutely no problem at all, of course.
It's also the one to use on the HD7 to get the maximum available storage memory.
It was quite expensive when I bought it, but it never bothered me, neither did the Sandisk Compact Flash cards I'm using with my goo old Canon EOS 350D camera.
Some Kingston memory card seem to have compatibility issues with some devices (I'm thinking about EeePCs, too, as it's a very frequently reported problem), but it may be essentially related to higher speeds, as those cards drain too much current. The symptoms are exactly the same : the device will sometimes boot when mains powered, but will crash as soon as you disconnect the mains plug, and won't boot at all from battery power.
The HD2 (and HD7, as it's exactly the same hardware) is known for not loving too much current consuming memory cards, so you'd be wise to stick to class 2 only, as it's supposed to be what HTC recommends.
If you still want to use class 4 or 6 cards... Then don't complain if it doesn't work.
And no, it is not "absolutely true". While the HD2 may not r/w any faster no matter the card, any class will work just fine.

Easy. I always first format my cards using a card adapter and a windows machine.
I know for a fact that class 6 microsdhc 32GBs work. It's what I have in my phone now. I also use a 32gb class 2.
I'm using a Kingston card. I've formatted, the computer sees a mass storage device with 30.2 gb available. However it locks the phone up in the boot sequence. Any Ideas?

What program did you use to format it?
One recommended app, outside of the built-in windows app, is SD Formatter:
http://www.sdcard.org/consumers/formatter_3/
(Link leads to the SD Association, of which I have no affiliation.)
If you have a card adapter, format it there instead of while inside the phone. Good luck
You suggestion is right.
Correctly formatting the card first generally solves most of the problems.
However, most high class micro SDHC cards will probably drain too much current from the phone. You have to find a really serious brand, and a really good one.
I've tried the posted formatting tool. Is there a setting or something I'm missing? After an hour of formatting, nothing, same problem.
I put the card in a 3 year old blackberry curve I had before the HD2, and no problem. I then put an 8gb class 6 card I had in that same blackberry into my HD2 and it worked fine.
I'm trying not to have to return this card because I don't want to wait another week and a half for back shipping etc.. Please give me some hope

SDHC card problem

I have a problem with 16 GB SDHC cards. I'm using nFinityROM 1.15 and when I insert an SDHC card it works for a couple of hours and then it just says something like unrecognized file system. When I remove and reinsert the card it says “Damaged SD card”. I cannot format the card with the phone (nothing happens) and my computer does not even recognize it.
I have tried two different brands (not budget cards) and the result is the same, an ordinary SD card works though.
I figured it could have something to do with the rom so I unrooted the phone and bought a 4 GB SDHC card and it have now worked for two days.
Does anyone else experience the same problem?
Have anyone tried nFinityROM 1.15 with an SDHC card?
Have anyone tried any 2.2 or 2.x rom with an SDHC card?
Wrong post
this post not related to tattoo general should move to tattoo accessories
Gee, thanks, nice of you to at least answer the questions while you bother with posting
Sorry for posting in the wrong part of the forum, if I could move it I would.
A lot of us here have 8 GB, but don't know about 16 GB. That is 8 times the capacity of the HDD in my old laptop!
I have just switched from nFinity1.18 and had no problems with my 16gb card.
I have just flashed nFinityGB-0.5 and still have no issues. Either upgrade to Nfinity 1.18 or you could try formatting the SD card to see if it resolves the issue (don't forget to format FAT32 and back it up first.
hope this helps.
I have tested and noticed that memory cards that are class 4 speed/specification do not work on the phone, so you should check that out.
Do the cards still work on other devices? I had a similar problem where my HTC Tattoo (unrooted back then) kept permanently corrupting memory cards: it fried any card I inserted in like 2 weeks. I had to send it back to HTC and they replaced all the internals. If your problem sounds similar, I'd check your warranty and send it back to HTC so they can fix it for you. Don't forget to revert to the original (unrooted) RUU. Good luck!
This sometimes happens to me. I have a 4GB card. So I don't think this is a issue on the SD card.
Thanks for the answers
The SD cards became totaly fried, did not work at all. After reflashing to stock and the 4 GB card had worked for like 4 days I rooted and flashed nFinity 1.18 and the 4GB card have worked since. I will use it as long as it works, if it breaks then I will send the phone to HTC.

I'd the same issue with my 16GB cards so I switch to my 4GB and it had work for 6 month ( 2 weeks on nFinity Rom)
My 16 Gb cards works fine on my daughters Huawei phone :-(
Maybe try to buy a budget 16GB card class 2 card?
Or maybe 8GB card will work on Tattoo.

Still working?
Because my girlfriends Tattoo killed 3 SD Cards (Class 2 8GB SanDisk). And the Tattoo from her brother killed SD Cards too. Only the stock (came with it) works. Buut it´s only 2GB Class 2.
Have no money to try more cards...
So would be nice to know, if it´s because of a wrong ROM...
The 4GB card (class 2) is still working like a charm
I have no idea why the cards get fried but I don't think the rom matters. My card has survived arcos roms, nFinityROM (Froyo) and nFinityGB (Gingerbread) and ofcourse the stock rom. My guess is that it has to do with the hardware but I don't know.
btw have you tried to return the cards to the store? I changed my cards when they got fried. They braged about "life time guaranty" so they hade no choice when I showed up with a fried card

My goldcard never worked with my 8GB, it used to get corrupt. I found an old 512MB card from an older phone and made it a goldcard. It worked fine.
Then I formatted my 8GB and use it as a general purpose storage.
BTW, I format with GParted on Ubuntu and never have problems with read/write on phone.
But... what is the problem? Does the tattoo give problems with fast cards or slow cards?
And.. in your opinion, will a "patch" in the ROM fix this? i mean if the SD driver is rewritten including a limitation to the speed, will it work?
I have a 8GB SDHC card (i don't remember the class but i will test it with crystaldiskmark) that seldom works..

[Q] Micro SD/SDHC card compatibility for the B&N Nook

Hi everyone:
I have been running 6.8 from my Sandisk 2GB unrated card. Although unrated, the card runs relatively fast with the Nook as measured to my Samsung Captivate or Apple iTouch (2nd Gen).
First Card: I backed up the image from my 2GB to a 8GB A-Data Class 6 card. Now this is where the problem starts. The Nookie boots up but down is acting slow and sluggish. To the point it is unuseable with lot's of FCs. I tried buring a brand new image and it is the same. I also tried the card as a data drive max'ing it out to 8GB and also using it to record video in my digicam, no problems.
Second Card: I then bought a Patriot 8GB class 10 card and copied the image onto it. Even worse. It won't even boot or get stuck in the boot process on the "Customted Froyo" screen. Try other images, and the same things occur. The card also works fine as a data card.
Third Card: Third time's the charm. I got this card from Costco. 8GB, class 4. Copied the image from the 2GB to the Sandisk 8GB, expanded the partition like the others. Worked like a charm and runs even smoother.
My question here is:
1) Is the Nook picky about micro SD cards? Seems like the faster cards are having compatibility issues.
2) For people complaining about performance issues running off of the micro SD card. Could it be caused by compatibilty issues I've experienced?
FYI, I've been running "Customized Nookie Froyo" from my micro SD card for about two weeks now with no problems. This will be my daily driver. I get the best of both worlds, Froyo and the B&N image.
Something to think about
Evidently the NC is picky about cards IF you are going to run from them - which is somewhat more intensive than is intended for an ereader additional storage device.
There are existing threads on the subject, just search TITLES for "card" in this Forum only.
Summary - The Transcend 8gb Class 6 seems to be the favorite. Some Class 10 cards don't work correctly in Nook. A-Data makes great Desktop RAM and crap SD cards. Sandisk is a safe choice when on sale, their Class rating is conservative.
Patriot 8GB class 10
I have the same card and works great. Strange. I don't know why you are having so much problem.
Did you try a new IMg? .3?

I tried .3, 6.8, 6.7, and HC all with boot or performance problems. I have two Sandisk8gb cards now and able to run all images with no problem. Typing in HC right now.

Bad batch? I tried hc .1 .2 .3 no problem. I guess I am lucky.
I have class 4,6, & 10 cards in 8Gb, 16Gb, and even 32 Gb. Mix and match of brands from SanDisk, A-data, Wintec..etc. Only issue I've run into is using any of my 32Gb cards, they just plain do not work right. Whether I use them for just storage or even a ROM running from them they are nothing but trouble. One thing I have noticed tho is DO NOT format the card using Windows before burning an image. You are better off using a3rd party app to format the card, it seems to work much better. Or format them with Linux if you have access to it.
BTW as for the 32Gb cards they don't work well with much of anything. And from reports I've seen on the web it seems to be a known issue where all the mfgs say they can use 32Gb cards but they do not have the software bugs worked out seeing as most people don't own or use them seeing as they are a bit pricey still. At least for a decent one they are
Hey quick question will2live what is the class rating and size on the Wintec card you're using?
I have a kingmax class 10 16 gb card....HC and nookie froyo refuse to boot......well nookie does, but in the next boot, hangs up...
