[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.

Rooted g1 no longer recognizes sd card

So I rooted my brothers g1 a few months ago and everything was great except that it could not connect to pc via usb. I told him not to worry about it but then he wanted to put music on his phone. He was messing around with the phone and he says he formatted something and now he has lost the ability to access the market as well as other apps he downloaded. For the life of him he cannot tell me what he did. So I check the sd card via card reader and I see that signed cyanogen mod (4.2.2.etc) is still there as well as other files. So I have no clue what he did and now the phone won't recognize the sd card even though its loaded and I can't flash him another rom so he can get the market back. Does anyone have a clue on what I should do???? Please help!!!!!!!
also tried other sd cards formatted to fat32 and fat with no luck.

i guess you gotta try a sd adapter, and put the files on there, as for the market app, looks like he needs to reflash the 1.6 firmware, and then reflash cyanogen if its the market apps, and google apps you are referring to.

This is a prime example of why you should never root someone else's phone if they don't know how to do it themselves. With great power comes great idiocy.

He probably formatted the ext partition. You may want to re-partition the card and reboot and see if it will pick everything back up. You may also need to start over.
When done, make a bart backup and tell him never format anything.

Thanks fort the advice guys. I'm gonna try to re partition the card. If I have to start over can I wipe to factory settings and will it return to the original firmware? if so I may do just that. In any case thanks for the input guys , love this forum.

Ok so I wiped the phone and got the market back. All the apps that he downloaded are in the downloaded section so no worries there.
I checked to see if the sd card still had multiple partitions, using a sd reader and paragon partition manager, and it does. The first being FAT32 and the second being linux. I still do not know why the phone won't recognize the sd card or any other for that matter. Any help would be soooooooooo appreciated!
Please help guys so I can get my lil bro off my back! ;P
Oh yeah I tried to re-partition the card with the paragon manager and its not going through. Any other type of manager I can use. I'm on windows7 64bit. This is really frustrating and I wanna get this fixed. Also when I plug the usb cable will recognize the external drive but when I click on it it says please insert drive.

[Q] CM9, Encryption, and Locked SD Card

So I installed CM9 on my TouchPad, Alpha 0.6. It's been running fine for close to two weeks. I went to turn it on after it had been sitting and charging (it was at no lower than 60% when I hooked it up), and it wouldn't turn on. I tried all combinations of holding down the various buttons nothing worked. Then, out of the blue, while trying to figure out that problem, it held down power and it turned on.
So it started booting into ICS, but instead of the home screen, it said that the encryption failed or something, and that I had to do a factory reset. I booted into CWM, and tried everything, including re-installing from zip, installing Alpha 2 from the zip, wiping the SD card, doing a factory reset...everything. Every time, I go back into the SD card and all the folders are still there. That's making me think that the SD card was locked by ICS somehow, and now isn't letting go, and as such, nothing can wipe the system.
Any ideas for a fix to this? I love CM9 on the TouchPad, but...this sucks.

Wow, nothing, eh? I've tried everything I can think of; the tablet is getting stuck at 12% when I try to run WebOS Doctor (and yes, I've tried every "stuck at 12%" trick I could find), and in general, it appears that writing to any part of the device is locked. I guess I'm going to warranty return it back to HP, unless anyone can think of something brilliant.

Can you boot to webos, maybe if you take the sd card out? If you can, do a full secure factory reset. Also try formatting the sd card (backup your files to your PC). You should try with another sd card also . If these don't work I guess HP warranty is the way to go. Take the sd card out before you send it back. Good luck.

Thanks for replying.
Yeah, I can boot into WebOS, but any changes I make there don't keep (i.e. if I install an app and reboot, it's gone when I get back). There isn't actually an SD card in the TouchPad, the internal memory just gets partitioned and made into an "SD Card", so that's out.
Probably just going to have to send it back...

Duhh! I knew about the sd card and the TP, I was thinking about my cell phone.
Try calling HP's butler service. I've been lucky, the guy I talked to was knowledgeable, but I've read that you can get someone who's useless.

Problem with a Class 10 32gb sd card

So, I was using a 4gb SD card class 4 and it worked flawlessly, but a few days ago i bought a 32gb class 10 Sandisk SD and it worked just fine for a day, after doing http://acetips.wordpress.com/2011/09/19/how-to-force-install-apps-to-sd-card-without-root/ process. The next day, my cellphone got stuck and it restarted a few times, and every time it turned on it recognized some apps and others not. After that I formatted it from both my cellphone and from my pc and it kept happening. Sometimes, after turning on the cellphone it says the SD is damaged and asks me to reformat it again. I even reverted the process mentioned before and rooted the cellphone, but the SD is still buggy as hell.
Anybody has any idea as to why this might be happening?
Im using the Galaxy Ace s5830L with stock rom and kernel.

You can't force move apps to the SD without root cleanly. You'll get problems. That's the whole point of rooting and what it stands for. If you're still after your warranty, there's an unroot file with the rooting one depending where you got it from. There's a thread here on XDA with both files. Then you can just install your carrier's rom and you're good to go.
You will need root for A2SD, and even then you gotta be careful how you do it. There are some apps and scripts that do better jobs than other ones.

Yes, I reverted the process mentioned before and I rooted my phone and moved apps with Link2SD and the same thing happened. After rebooting my phone once it stopped recognizing some apps randomly (it says the ones that the phone doesn't recognize are not installed). But when I switch to my 4GB SD card it works fine. Then I formatted the card and the phone and tried to make a partition but as you know it didn't work.
Maybe it's a size problem, I don't know. It's not that I need that much space but I will not even think about space with that SD card and also I've already bought it, haha. I'll go to the store where I bought it tomorrow anyway.
Thank you again for your time!

Oh alright. Good thing you solved it. Also, I don't recommend Link2SD as it doesn't free that much space compared to better alternatives like INT2EXT+ or DT's A2SD.

Yes, I know that now. When I change the SD card or find what's the problem I'll start from the beginning and I won't use Link2SD.

what partition type did you put on your sd card? n its possible that the partition is corrupt i had a similar issue not so long back
i formated the whole sd card using minipartion tool then made a 2gd ext4 split works fine now

I followed this tutorial to make the partition http://forum.xda-developers.com/showthread.php?t=1477996 (not sure what type of partition it is). But the SD card had been working bad before I tried to make the partition.

[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.
