HELP SD card not recognized

Ok this is extremely annoying. I got the g1 and rooted with 1 click rooting cyanogen 4.0.4 rom. It was so simple and worked BTW. Later I used the hardspl so that I could do apps to sd. I have had the phone for 7 months and have used custom roms since I’ve gotten it.
Following this tutorial http://forum.xda-developers.com/showthread.php?t=535232 I tried to partition my 8g sandisk micro sd card. Now I probably destroyed my sd card (Nothing to big). And I am stuck at the g1 screen (pretty big). When ever I try to flash a different rom with a different or even the same rom I get an error acout the sd card “E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0) (No such file or directory) E: Can't mount SDCARD:"
With around 8 hours of digging around on forums I have decided that I might have to get a replacement unless someone could help me revert with access that I have to the recovery to allow my sd cards to be recognized.
Note: I didn’t install the Cyanogen ROM - Download v4.0.2 or Cyanogen Recovery 1.4 - Download as I had a better one. Hince my problem, and did use the apps2sd.apk. Things didn’t go wrong until I typed in “upgrade_fs” . After doing so my phone would not boot up after I restarted it.
Something tells me that I changed something in the phone to allow apps to sd partition 2 and I need to be changed back to the default, as I can’t even flash another rom to fix this problem. Any help would be greatly appreciated .

willl your phone boot when you remove the sdcard

My phone will not boot after removing the sd card.

One thing that I forgot to mention above is. While using the phone after my uncessful attemp to partition my sdcard, the top notification bar was displaying "The SD card is blank or using an unsupported file system." After messing with it a bit i decided to reboot but it froze. Being impatient I pulled the battery from the back of the phone.
Looks as if files are missing from the Cyanogen 4.0.4 rom. As when I type “mount sdcard” is displays “mount: mouting /dev/block/mmcblkop1 on /sdcard failed: No such file or directory” Sounds like I am missing mmcblkop1 from my phone now? Apps2sd.apk doesn’t change this file does it? I'm also wondering if you change a file to look somewhere else for the partition part of the sd card? And if so how would you tell it to look for the default?

Tried this "flash_image recovery /sdcard/update-cm-4.0.4-signed.zip" and it displayed this "usage: flash_image [-d] partition file.img" does this delete the partition of the sd card or what is this referring to?

I think you 'bricked' your sd card.
Try format it with SD Formatter.
Worked for me.
Because you did use App2SD, you have erased app data, so setting up your G1 from scratch is your best option.

Ok first of all using that guide to install apps2sd on cyanogen's rom is what messed up your phone. Cyanogen has clear warnings about this in his thread. Now that the damage is done lets fix it. Can you boot into recovery by holding home and pressing power? Is there an option to flash any zip file?

After rereading your post i see that you don't have recovery 1.4.
You need to do step 4 HERE when you're done do step 5 to install cm-recovery-1.4

After trying different things with the console as I posted above the phone allowed me to install the Cyanogen 4.0.4 from the 2gb sd card. For some reason the phone would not allow me to do this before. As it wouldn't recognize the sd card, or that it had 1 for that matter. What would cause this problem? Maybe a faulty sd card? But I swapped to the 2 gb sd card that came with the phone and tried this numerous times before. Glitch? Why work now? I'm so lost.
I'm so glad that this worked this time though..... another save for this g1. Its taken a licking and it keeps ticking. I have dropped it 14 feet from the top of a railcar. I have crippled it 3 times now as it wouldn't allow me to get past the g1 screen. A simple flash from the sd card allowed me fix that problem. I have also dropped it in water. It was submerged for around 6 seconds in a leather carrying case that clips on your belt. Fast thinking allowed me to remove it from the water, pull the back off, and pull out the battery. I allowed it to dry in the car for around 4 hours and then put it in a bag full of those "do not eat" packets that come in most shoes for 24 hrs. Thanks to Walmart for the donation. Probably the best phone that I have ever gotten.
Well looking over the history of the phone I understand now why it may have done this to me. However it shows that by being persistent you can figure out most things. I appreciate all who have made these guides that make my g1 ownership so much fun.
Now go to get that apps2sd working. Another method probably.

I did have recovery 1.4 installed at the time the g1 quit working. I never downgraded and was able to access the recovery the entire time. But I kept getting the error “E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0) (No such file or directory) E: Can't mount SDCARD:"
I did change the sd card at this point but had the same results.
As you may have noticed i didn't read Cyanogen thread discussing this.
I found the guide for apps 2 sd here: http://forum.xda-developers.com/showthread.php?t=535232 and read through it. Sounded easy enough and well tried. With failure of course.
I was under the inpression that apps2sd already is included in cyanogen 4.0.4 all i needed is to partition my sd card.

Unfortunately that guide is still a sticky and someone uses it at least once a week and we end up with your problem every week. ivanmmj added a warning to the guide a few mins ago. I'm glad you are working now. You are correct about apps2sd being included in cyanogen roms. In post 3 HERE I've made a script that will partition your sdcard for you.

[solved] Card "Preparing SD card; Checking for errors"

Hi all,
I have a problem with my G1, running on latest Cyanogen mod. After restarting the card cannot be read and it is seems to be checking the sd card, if it really happens I dunno. What is weird is that I can access the card from recovery mode (shell), and it is not damaged (at least the windows doesn't detect damage while it is in the card reader. So that implies that the problem might be in the Android system.. anybody has a clue how to solve this? Thanks a lot.
Edit: solved it, deleted fsck_msdos from bin and it works flawlessly again

Can always wipe and reflash. Or if you have another sd card laying around and put that in to see if it recognizes it.

I'm having the same problem How did you delete the fsck_msdos from the bin?

your phone should rooted
then download and install root explorer
in the root explorer go to
system /bin
and delete fsck_msdos
now reboot your phone

I was having this same issue..it would typically take up to 5 minutes or more to "check for errors" after a boot.
To fix this I backed up my sdcard, reformatted, copied everything back, then reflashed. Everything was fine after that.

i have somewhat the same problem but in my case it sometimes say blank sdcard or damged sd card it read fine when plugged into an sd card reader any help

Thanks. It worked by simply deleting fsck-msdos but it keeps giving SwiftKey3 error " unable to load language packs". Keyboard still OK. I have xperia x10 mini rooted running android 2.1 E10i.

Well, after getting other errors such as "no enough space" from Platinum Backup (there was a space on SD Card), I had to go to Format the SD after copying everything. Then I copied back the important folder the SD. I also had to reinstall SwiftKey. Now everything is fine and no data loss.

Simple fix, Difficult decision. Remove SD Card from slot then Factory reset phone. Once it comes too just go through all steps to setting up device then reinsert the SD Card into the slot. BOOM!

thank you very very much it worked for me

Bloody Brilliant. I have no idea why I could not find this solution two years ago. I have spent several hours searching for this solution, several times. In my case, I needed to remove the fsck.exfat file in the /system/bin folder.
My attention span is extremely short. I have been living with a 3 to 4-minute card scan for a 256GB microSD in my Samsung Note 3 for two and a half years. For all of the reboots I have done (which must be near a thousand, if that's not severely underestimated) I have had to deal with waiting to use my phone. I can't tell you how discouraging it has been to have such a powerful, useful device crippled by such a stupid flaw: that of checking the SD card that you rarely remove, for errors, every single time the phone is rebooted, even after graceful reboots called by the "proper" methods.
I can't tell you how many times I have rebooted my phone, only to forget the reason I rebooted it, because my phone took 4 minutes to reboot.
Productivity to the cubed-root.​Pisses me off.
Someone who has more voice than me please get the Android People to change this. As of Nougat, this is still the default behavior. How can an organization be so stupid...? I have no doubt that just this flaw has sent many people to the Apple camps. Who the cuff in their right mind would want to deal with such a hassle?? Are they seriously unaware of the trend for people to actually believe that their devices, machines and technology ought to be doing things faster than previous generations?
(Please just take the following cynicism with a grain of salt. I just learned the above fix, something I really should have figured out a long time ago/kicking myself!!) :crying:
For the anally-inverted who might bring up the obvious argument that your phone will no longer be able to detect or fix corruption, all that needs to be done is the following:
1) move the fsck.exfat (or whatever the formatting) file to a different folder. In my case I moved it to the /data folder
2) use some delay scripting program that will symlink the fsck.exfat file to a tmpfs location say, 30 seconds after boot; or longer if needed. This intermediary step is necessary in order to create a temporary symlink, which will be nonexistent upon reboot.. If we didn't create a temporary symlink, the fsck.exfat command would be immediately available after each reboot (which we don't want) because symlinks are normally permanent. Therefore, this step will need to be run after every reboot (but again, time-delayed).
3) the last command is to create another symlink, linking the tmpfs fsck.exfat symlink created in the last step back to the /system/bin folder (or wherever it originally resided). So this is a symlink of another symlink. This step actually should only need to be done once, since this symlink should remain after reboot, even though it is initially broken upon reboot until the previous command recreates the intermediary symlink. It should become effective again when the previous step is run by the time-delayed scripting program.
Now your phone has the ability to check the card upon you calling the fsck.exfat routine through normal means, one of which can just be a simple unmount -> mount request from the Android system settings . Your card won't be needlessly fsck-checked to death every bloody time you reboot your phone.

Stuck in bootloops, not sure what to do

I recently tried to flash Fresh Toast 2.1 and after 15+minutes my phone was stuck in a bootloop. I rebooted to recovery and deleted all the data and cache. Now no matter what ROM i try to flash it just keeps booting over and over. Anyone have any ideas? I was using apps2sd and completely formatted the sdcard, would this have affected anything? Also tried nandroid back up, but says "No files found" when I try to do so. Also when i try to format the sd:ext i get an error mounting sd:ext

In recovery try and format your sdcard with only a fat32 partition. Then try and enable ?MS-USB? and copy a ROM to your sdcard.Wipe data and dalvik and then flash ROM.
If that doesn't work try replacing your sdcard with another one.
Or you can push your ROM.zip to the sdcad through adb without mounting the sdcard
A2SD will only work if your sdcard is partition with EXT and swap. So if you don't have it partitioned then apps will install on your phone.

I gave it a shot but no luck, i am using the clockworkmod recovery 1.8.1.4.

I had the same issue happen the other day after a wipe and reinstalled rom... I have the same clock work mod you have also... what I noticed was that my phone only did that when I had the sd card in but once I removed it (after several hours of flipping out over it!) it booted fully.. but every time in reinserted the card, it rebooted.. so what I did was used paragon partition manager to create 3 partitions on the sdcard (i have an 8gb card) and made 2 Linux ext2 partition of 258mb or something close to it and the remaining was formatted at Fat32.. after I did this, I re-flashed my rom and everything has been working fine ever since... it may have been some corrupted files in the 2 Linux partition or something because I was running all my apps from the sd card and I had noticed the other day that every time I connected my hero to my laptop via usb, and launched pdanet, my phone rebooted...EVERYTIME.. and this is what led me down this road... If I made any mistakes here, I'm sure someone will correct me, as this is my first post...

Would you mind posting the steps to do that? Im pretty computer savvy but I need some steps to go from. Would I be better off picking up a new SD?

pulled the SD and it booted, thank god lol. Thanks for your help guys!

no problem... glad I could help.. as for the new sd card, you could very well just get another, but I managed to keep the one that I had but just reformatting it and re-flashing my rom (Damage Control v2.08.1) and it's been working fine since then..

[Q] External sd card won't mount

After every time I restart my phone and it turns back on my phone will never automatically mount my sd card, so I have to go into setting and manually mount it myself which normally isn't a problem but every once in a while my phone won't let me mount it, when i click on the mount sd card button, it goes to another screen that has a title Reset? and the whole screen is blank. I have reset the phone, taken the sd card out, I have done everything that has normally worked in the past to get it to remount but this time nothing will work. Has anyone else had this problem, or any suggestions how to fix it?
Thanks

Sorry, no help for you, but I have the same problem here. Started just a few days ago. I haven't made any changes to my settings that I know of that could have caused it. Anyone have any suggestions for getting back the ability to mount the SD card?

Yup, me too, just rooted my phone trying to get cifs manager (cifs.ko) installed and working with my win7 machine (no luck w/that yet either)... since then the external sdcard unmounts from time to time and restarting the phone requires a manual mount

Fixed?
What I had to do was basically move my entire sd card on to my computer then I formatted my sd card put only my necessary things back on there and it fixed it, stupid but it got it to mount right away...oh and I formatted it though the phone erase function not using the computer, so I didn't have to take the sd card out again.

Tried the erase all, but no luck... I suspect it's related to installing busybox... tried unistalling that without success too... would installing another ROM likely fix that, and if so any recommendations?
Talking about an HTC vivid

I'm having the same issue, except it partially mounts the external card (only shows a couple of folders but not the /music folder with 2100 songs along with 4-5 other folders)...Only way I have been able to fix it is to connect it to the PC as a disk drive then disconnect it, then all the folders "reappear".
If I put the card in my tablet I have no issues.
I tried a new card but the problem is still there.
Any help or suggestions?

Good Evening OP,
I had a problem like this earlier today. I finally rooted and flashed a new rom (PACman). I used CWM as my recovery, and apparently this is part of the issue. You need to use TWRP for your recovery instead. Their website is at http://teamw.in/project/twrp they have instructions located there on how to install TWRP onto your Vivid. I used the fastboot method, then changed the settings in the 'Mount' tab to mount SD Cart, Internal and Use External SD. Worked like a charm. And since it's touch based no more using the volume rockers and power button... Hope this helps! By the way http://forum.xda-developers.com/showthread.php?t=2109140 had the initial lead to install TWRP instead of CWM.

[Q] Internal storage and ext sd wont read.

Ok first off I have read through a lot of different forums from here and different websites. Could not find a solution.
MY cappy was rooted and I was running cm9 on it for a while working great.. decided to give cm 10.1 a try. Well it worked for about 2 1/2 months. doing the updates that came out every day. Then the other I was playing a game on it. I stoped the game unplugged the phone from the wall charger went outside to smoke and went to check the phone. It was a black screen where it was semi light up though.
I of course tried hitting the power about 15 times no response. So I took out the battery and put it back in. It rebooted into recovery. So I hit reboot phone. Went back into recovery. Went in cleared cache and dalvik cache rebooted. Went back into recovery, so from there I went to install zip from sd card. there was nothing on sd card.
I then put it into download mode and using odin I brought it back to stock 2.3.4 after odin had suceeded it installed everything on phone. But it came with error no internal storage found. It booted fully. So then I tried heimdall one click it then did the same thing I cleared cache and did a factory reset. IT rebooted fully.
It only works when I have my ext. SD card in the phone though. If i pull my ext sd card out it will go into a boot loop. IF i put my ext sd card into another phone and back to my cappy Itll stay in boot loop. I have formatted sd card put it back into the phone and rebooted. and same thing. bootloop. So I then have to go through the process again to get it semi running. It wont read ext or internal sd card when phone is fully on.
So is there any way to get it to read internal storage again? Or even ext. I dont understand why it will run with the ext.
Any help will be appreciated Thank you.

Your issue is kinda odd, the only thing I can think of is the EU bug but that's on ICS and you said you were on JB. Either way, could be worth looking into, there's a thread for it in here.

Well I was on cm 9 then went to cm 10.1 4.2 I have no clue I looked into the EU bug tried to fix it no luck. I can put the sd card on it and flash the stock rom and kernel and it will run just without it reading internal or external sd card

the external sd card has probably got your .androidsecure hidden folder on it, possibly more. if your phone had the eu bug, then CM10 recognizes that and switches the mounts.
if you boot the phone, go into terminal emulator, type su, then type mount, and post the output, it would probably give us a clue.

No the android secure was on the phone, The external sd card was never in my phone but I was trying different things and if i format my sd card put it in the cappy then do the flash. It will work but as soon as I turn the phone off and put the sd card in another phone, It has no files. but when I put it in my laptop it says there is only 5 gb on it but it is an 8gb memory card. Then I have to format twice to get my full memory from it on another phone.
