I think i may have come across something of a program corrupting memory cards. Twice in less than a week , I have had an SD card get corrupted by the Eco. Both times I was running the program wardrive. Both times, the program was either running or had not completely shut down before I did a restart or shutdown. When the phone came back up, the card was reported being corrupted. This time, I have everything backed up at home.
Could someone verify this so I can make sure it isn't just me and I will tell the programmer of that app about that.
The test is very simple. FIRST, BACK UP ALL YOUR CONTENTS OF YOUR CARD TO A SAFE PLACE BECAUSE THIS COULD BORK YOUR CARD (A FORMAT WILL FIX IT I THINK). Install the app wardrive. Turn on your WiFi and go and fire up the program and go for a walk or drive with the program running. While its collecting data, shut down the phone or restart it if you have that app to reboot with. If what I suspect is true, the card will be corrupt when the phone is restarted. I tried rescuing the info on it but it didn't work. Post your findings here. I have a sandisk 16gb card BTW. If you format the card and copy your backed up stuff back to the card, everything "should" be okay then, although I am not promising any success. Try at your own risk, but I would appreciate if someone else could verify this.

I don't know if it makes any difference but I'm running Damage Control 3.2.3 rom

Testing now. Ive used wardrive several times without it affecting my sd card. but lets see......
Booting up now......
Nope. Everything is still working just fine on my SD card. Guess its just you. LOL
Im also on DC 3.2.3 FYI.
Another thing I forgot to mention that might make a difference is that before, I had maybe 6.5gb of stuff on the card. About 5.6 of that was around 4000 apk files. Maybe having that many files had something to do with it. What I'm thinking is that while the or a program was writing to the card, the system shut down before it finished writing the file(s) or updating the file allocation table/list on the card. Windows did that stuff all the time if power was lost while the harddrive was accessing. When you rebooted, you got the bsod or it wanted to run check disk. Any other theories?
I'm trying this experiment on the same card but empty and cannot recreate the problem. I will have to throw all the files back on when I get home later and see if that has something to do with it.
One last note:
Last night I spent well over an hour formatting this card with xp in fat32, just like the phone does. I did a full format, not quick. The phone seems to just be a quick format.

So my SD card was removed (kids) and now I cannot access any of the apps on the card. I've tried unmounting correctly, replacing the card, taking out the battery, etc. and nothing is working.
The fun part is that all of my apps needed to recover are on the card (ROM Manager, Titanium Backup, Market, etc). I'm guessing I should have put those in internal memory. I've removed a lot of the bloatware, including the apks that allow you to sync to a PC (I never use that method), so I can't get access to the SD card from my computer. There are very few apps in my internal memory. I'm rooted running using NFX-Sprint.STOCK.2.32.651.2.ODEX.A2SD. Any suggestions on what to do? Any help is appreciated.
So you have confirmed that the SD card is operational already?

IDK if that rom comes with the "dev tools" app, but if so you could try to run the media scanner in there, or an app from the market that does something similar. As for accessing it, you should be able to do that from recovery and adb even if the phone can't find the sd (assuming the SD isn't fried). Also, does it work in a card reader alone? If not you may be hosed. I never put gapps onto the SD, and never TB either. For future use you could try firerats, it increases your internal memory, that way if your sd fails your apps are all fine.
The sd card does work b/c I'm able to access photos stored on the card (when sending an email I can attach the photos). As for running media scanner, I don't think this rom has it, but I'll look. As far as using recovery, how would I do that since I can't access ROM Manager or anything. That may be quite a noob question so forgive me there.
Reinstall rom manager and reflash clockwork. Hopefully you had the newer version or you'll have corrupt nands.

To access recovery without clockwork, you just need to go into your bootloader (on evo you get there by turning phone off, hold volume down and press power button to turn on, should open bootloader,) and you can boot to recovery from there. May be same combo for heroc, or may involve trackball. Im not sure how you can fix your situation from recovery, but bootloader is the traditional way to get to recovery. Good luck.

My nook color stays not much longer than 1min after loading all the apps & just after that it reboots. I've tried installing a fresh rom couple of times & wiping each & everything but just after installing all the apps again, it reboots. Have tried both by installing it manually & restoring through titanium backup as well, but same result. It works fine only when I remove my micro sd. I know that some apps doesn't works when installing in micro sd & that's why I've installed all my apps in internal memory. I never faced that issue when I was using Phiremod v6.3 build. Recently after moving into the latest nightly build, this issue occurred. Please tell me how can I resolve this issue? I've been trying to find the solution from so many days but couldn't able to find. Thanks
You could use ROM Manager to restore the last ROM if you did a backup or just reinstall it. I am a little confused about what you mean by loading all the apps. Apps are generally loaded as you use them, not at boot up. When you first boot up you can usually see the SD card icon at the bottom of the screen before it gets mounted. It is possible the card got corrupted. If you don't have anything on it but app backups and it works fine when the card is out you could try reformatting the card on your PC or with a camera that uses micro SDHC cards.
You also might have a misbehaving app loading on startup.
When I first boot the system, the sd card icon shows at the bottom of the screen & disappears after loading all the games from it. After that I can see all my apps & games in app drawer but after a min, it gets reboot. I only have games in sd card, not a single app & neither any app in my internal memory which loads at startup.
Well if the nook boots and runs just fine without the SD-card inserted, then we can be pretty certain that something on the card is messed up. Lot's of possibilities: Corrupted .apk file, partially corrupted file structure on the SD-card itself, Hell it could also be auto-update panicking because it's trying to update an app that has yet to load off the SD-card.
First thing I would try is formatting the SD-card within CM7.
Also try turning off auto-update
If that fails, connect the SD-card to your computer and scan it with windows to check for any file table corruption.
If that fails, it's hard times ahead for you. You'll have to go through the apps one-by-one to see which one is being the little bastard.
Good luck.
Thanx for The help. But all I have on my SD card is just game. Before installing anything on my internal memory, I restored my games backup 1st to my SD card through titanium backup. It was then working absolutely fine. After that I installed apps manually just to see which app is causung error. But all were installed without any problem, used for a while then I manually reboot. Since then I am getting this issue.
Is this the right forum for support questions?
I have a MT4G running 2.2.1 rooted
I have been having this problem for a long, long time. I'm at my wits end.
If I remove the SD card, plug the phone in to the PC, shut down, or restart then the phone seems to forget how to access apps that are on the SD card. They show up on my home screen as the generic android icon(all of them the same) and don't appear at all in the app drawer. Apps not on SD work fine. I can go into Astro and see the files, all of them. I can open videos, music, pictures, etc. that are on it. But if I try to click on an app that is installed to it, it says "Could not launch the requested activity." App Manager shows the apps, but with generic icons and no info and all apps show computing instead of sizes. Settings>SD Card shows the card & the sizes but won't unmount.
On top of that, it won't let me install or uninstall any apps unless I remove the SD Card. Sometimes even when the SD card apps are showing up, I still can't install apps.
I've been at this for months now. I have tried EVERYTHING every single responder to previous posts has suggested. Pull the battery, pull the SD card, pull the sim card, unmount(would freeze and not do anything), reset, format, different SD cards in this phone(found those apps fine that I also had), this SD card in other phones(found it fine, but only the apps that that phone also had), This SD card in the PC with no phone(found it fine), mounting it through recovery, fixing permissions, deleting and reinstalling things, EVERYTHING! I am so far beyond frustrated at this point I'm going insane.
I can get the apps back after dozens of tries of pulling the battery, pulling the SD, rebooting, shutting down, etc in various orders and sometimes it takes days to get them back. But to then say, "OK they are back I'm never restarting again," is unrealistic and then of course apps stop installing/uninstalling and I have to reboot. And poof, gone again! :-/
I have everything thoroughly backed up with Titanium Pro and I did a Nandroid backup before doing a factory reset, but my god was that annoying having to redo everything, and it didn't even work. I've uninstalled apps individually to see if it was a specific app. I've done the reverse and uninstalled everything and reinstalled one at a time to see if one triggered it, and it kept happening randomly, never twice after the same app.
So the only conclusions I have been able to form are that it's not any of the apps, and it's not the SD card itself. Someone please, please put me out of misery and give me a new solution!
Try new SD card.If it is still happening, try flash anther Rom.
Thanks for the reply.
Tried new SD Cards already. Will see what new ROMs are out to try.
Out of curiosity, did you format the card to FAT 32?

Yes. I formatted it on the pc and also tried a format in the phone the one time I was able to get it to unmount.
custom recovery
if you have a custome recovery try format the sd by this way try mount and unmount by recovery and say what happens
Dear all,
I have a N9005 (eu) with 4.4.2 stock. Never rooted.
Since a couple of weeks, I notice a strange behavior. Quite often I find broken thumbnails in the stock Gallery app, sometimes the actual photos I have take are not visible.
At the same time, it happens that I download and install an app and it won't run, giving me an error in com.appnamewhatever. After a restart, I still see the link to the app on the home, but as I click it says app not installed. After I reinstall I can often run it np.
It gives me the feeling that the internal SD Card is dying. Is that possible? Can I run some tools/fixes to prevent or check it? (with no root required)
Thanks.

1. Take a look if your photos and pics are in SDCard.
2. Take a look if you have the apps installed in your SDCard too (Aplication manager -> SD Card -> App marked to move to SDCard)
3. You will have to take off the SDCard and try making photos and installing new apps (change your SDCard for other new if this go ok)
Tell me what result do you have in your tests :highfive:
Man, you are right. I had not moved any app intentionally to the external SD Card so I did not think that would be the case. But that's what happened, the failing apps were on the external SD and so are the photos. It's a SanDisk Class 10 64 Gb.
So no way out other than substituting it?

1. Take a look for what you can recover of your SDCard and copy it to your pc.
2. Format the card in the phone for last option.
3. Try again to put photos/apps there.
4. Good luck :highfive:
The corrupted photo's on the SDcard are a problem directly related to KitKat's increased security. It affects all KitKat devices. Any photo's on the SD randomly corrupt over time. The only solution is to put them on the internal memory.
The apps are a new one though. I've had apps suddenly become semi-uninstalled because I was dumb enough to mess with the Android_secure folder, but not with the errors after install.

Jeez that's crazy. I triedo to run a chkdsk on the card from windows (in a SD reader) and it got me a gazillion errors.
So now I proceeded to salvage what I can. I will try to format it (in the phone? in windows? still not sure about it) and see what happens.
Luckily I was able to salvage 99% of the photos.
I just remembered that I did something very unortodox, more or less at the same time problems started: I removed the SD Card with the phone still on. Yes, you can barely do it without removing the battery... I though "let's see if something bad happens". Maybe it started to corrupt the FAT or similar.
Anyway, please feel fee to point me to a thread or good article on this, I find information very scattered. Is there any advantage t oformat it in FAT32, NTFS or exFAT (assuming I can even choose)?
Thanks

I find it fairly easy to do. It's also perfectly fine, as long as you unmount it first in settings.

Fat32 is the common format IT doesn't allow for filesizes over 3.9GB, so if you intend to use t for films, use exFAT.
NTFS can't be read without root. Don't use it.
exFAT is practically the same as FAT32, except that it allows for larger filesizes.

Thanks for the infos. At that time I obviously did it without unmounting it first (no fun in life without some screw-ups). Regarding the formatting, I seem to be unable to do it from the phone at the moment.
It unmounts it, says checking it. But doesn't format it. Trying from windows now...
Here are some updates.
Formatting in either windows (stock function) and phone was a no-go.
However, I dowloaded and installed SD Association Formatter:
https://www.sdcard.org/downloads/formatter_4/
and that did the trick. Now the SD Card is finally empy.
Also I strongly suggest using this tool instead of windows proprietary, because it's simply much much faster.
I will try and load it back with the stuff I had before, including pics, and see if I get the corrupted data again.
A difference is now that the chkdsk tool from windows says that no errors are found, unlike before. Let's see how it goes.
Final update to close thread:
The SD Card, a SanDisk UHS Class 10 SDXC, 64 Gb, had been declared dead.
It was possible to write data on in with seemingly no errors (from chkdsk) but all the data turned out to be simply corrupted.
Will send for replacement.
I have seen many comments on this card failing, so I would not recommend it. However, I think that this case it was not KitKat's fault.
Thanks for the inputs.
Do not blame the card yet
I am having the same issue with the same card, but it is limited to Note 3(N900).
Every now and then it becomes inaccesible, the photos appear broken, music player stops etc. It is not related to use of any particular app. When it happens, the card is still visible in Settings/Storage, just no app including mounting has access to it. What helps, is the old reboot fix
Happened on official KK, as well on LP. Device is stock unrooted N900.
The card is working without any problems in Note 1,even in Galaxy duos, and there are no issues writing/reading in windows nor linux. Something tells me that hardware is to blame.
