Corrupted MicroSD Card - Apps2SD

I have this problem that keeps repeating itself.
I have been using the latest BiffMod Rom for a few weeks, all has been fine until I moved some apps to the MicroSD card via the inbuilt application manager.
The phone works fine for a while and then one day, nothing. the phone doesnt want to boot or anything. After some investigating it turns out its the MicroSD card that is corrupt.
If remove it from the phone, the phone operates as expected, If I insert it, I either get freezing, or the safely remove SD card message. The card wont mount.
I have tried the card in a Windows PC and it will read the Fat32 but freezes after a while.
Now this is not the first time this has happened and the pattern is emerging that it seems to be when ever I move apps to the SD.
Has anyone else had similar problems, I have gone through 3 of the same card in about as many months, luckily I have a bunch of cards from work. But its super annoying.
completely The card ends up been completly useless.

Well, for one, Biffmod moves apps2sd automatically, using scripts and when you do it manually, you are messing with the mod. So, thats where you messed up.
Secondly, I too messed up a 16GB Class10 SD card but, was able to fix it by reformatting it in ubuntu then again in Amon_RA recovery menu. I originally had it formatted 1024MB ext4/96MB swap...when I re-parted it, I had to change the sizes for it to work. Now, its 512MB ext4/32MB swap.
Third, a guy (MrBurrito) gave me this script file he made to try and fix the card. You copy it to your sd card, flash it in recovery, wait 10-20 seconds after it finishes and, then reboot. It didn't work for me but, I'll attach it, maybe it can work for you.

[Q] Phone keeps losing installed apps on SD card

So I've been having this issue for about a week now. All the apps installed on my phones SD card once I reboot are not loading up. I know the data is still there because the first time that it happened I spent the better part of day freaking out thinking everything was gone gone. At some point I thought of checking of the data by plugging in into the computer. Turns out (1) all the apps miraculously return (2) I can't mount the SD card anymore (3) I can't unmount the SD card anymore either.
What is the deal? It's kind of annoying to lost everything every time you reboot. I'm not really in the mood to tether my phone each time for the unforeseeable future just to keep everything loaded. Has this happened to anyone before? What should I do?

What do you mean, the icons? I'm going to assume that's what you're referring to, for this reply...
If that's what you meant, icons on the home screen take a few seconds to get themselves drawn, if apps are on SD.
You can switch to a different skin then switch back to your original skin, to get them to redraw. Or delete/reposition them one at a time. It's a workaround, but changing the skin temporarily is faster.
It's a sense bug, I'm pretty sure.
Doesn't happen if apps are installed on the phones internal storage, so until they fix it, move your apps onto internal storage, if you don't want to deal with this each time you reboot. They run faster if they're not on your SD anyway.
Unless you have waaaay more apps than you really need, of course.

Sorry should've been a little more specific. The shortcuts on my home screen are all no longer working and I'm well aware of how long it takes for sense to load them up on startup but even when I go to display all apps it only displays the apps on internal storage. In fact each and every app on the card (in the apps settings) has a funny icon that has a little "sd" on it now and just says computing and will not load.
And since writing this I can no longer get the phone to load any apps from the sd card by tethering it to the computer. It's still accessible - just downloaded today's song from amazon and played it - but apps on it are almost like they're gone.

This happens to me sometimes too. But usually when it happens to me I can go into Settings - Applications - Manage Applications and move the troublesome app to internal storage, and then it's fine. It never completely disappears.
It might do you some good to reformat your SD card. Move everything off of it first, then format it, then put everything back on.

Is it the stock 8GB SD card, or a different one?

Sold, since I can no longer access the SD card and I've got nothing to listen to at work...

Yup.

@homeslice976 copied, formatted (made sure it was FAT32), copied everything back and no dice. Same symptoms, Apps will not load.
@zuriken I don't know why you asked about the stock SD card or not, do you think it needs to be replaced? It's only been since February.

Did you do a full, not quick format? Scan for bad sectors/errors?

full format, chkdsk /f, still nothing though. This is honestly getting to the point where I'm tempted to switch to another phone. Why can't I access my stuff?
Another new bonus, every time I get some sort of alert it now plays random MP3s from the SD card. What is going on...

I'd try a brand new, good quality SD card before resorting to switching phones.
Have you flashed any custom roms or anything? I didn't see you mention either way.

It's gonna be a little while until I can try a new SD card but I'll get back to you.
The only ROM I loaded was the one to originally root that removed the uploading cap from ATT.
I also solved where the random sounds were coming from apparently it doesn't want to play my selected theme and no matter what I do the only one that works is the original HTC default 2010 one or if I download any only the Celesta theme plays... I have a sinking feeling that copying all this funky data isn't going to resolve anything but I'll give it a go.

Good luck.
Since you haven't been messing with multiple roms and such, I don't know what else it could be, other than the SD card taking a dump.

Soft reboot when Ext SD card in Cap

I am having maddening issues with my Cap (running KJ3 rooted). When the SD card is inserted, it becomes very unstable and soft reboots - usually on startup (and repeats ad infinitium). If I start up without the SD card, I am stable, but I have many apps that KJ3 defaults to installing on the SD card. The problem occurs whether I insert the card before boot up, or insert after it has started up.
I have the same issue with 2 different cards. I tried a brand new class 10, 16GB. I restored apps from my TiBu backup which I had copied from the old card to new (on PC) - not sure if that is the issue...
Anyone have any ideas?

Well, if I am not mistaken, apps which are installed to SD are not on the removable SD card, but on the captivate's "Internal SD", which is the 16GB... well actually about 13GB after the phone's "internal Storage" partition is lopped off of it.
I would try a reflash and then test it before you install the apps.

I've been down that road more times than you can imagine - flash, wipe in recovery, and reload. I had thought that it was the .androidsecure directory on the external SD that held the parts of the apps that move. what is clear is that this only happens with the external SD card inserted and mounted, and almost always happens within 10 minutes of startup or the previous cycle, i.e., before any program launches other than TouchWiz and often before any email sync (this is my work phone, syncs with Exchange 2007 server).
I did get a list of all apps that have the start on boot permission, not sure if any of these are regular problem children, they are, on my phone (not sure why some of them need that permission, but that's a different story):

Did you move the apps back to internal memory after restoring them? Iirc, when using the later leaks, they install all the apps to external sd(if there is one in the phone).

Going to start doing that, the next time I have a stable spell with the card in. The problem is that the failure is intermittent. It doesn't fail every time I have the SD card in, but every time it does fail, I have the card installed, and it usually takes awhile before it starts working again. Thinking about another factory reset and then reinstalling apps without TiBu help or the card in, at least until I get all of the ones that startup in main memory to eliminate that possibility.
Of course with the Epic finally getting the official upgrade, kind of want to hold off until the Captivate image finally comes out, that way if it is a hardware problem. I'll be on stock for the warranty exchange.

Arggh... maddening problems continued.
The phone stayed up (with SD card in for about 16 hours), during that time I moved every app with the permission to launch on boot to main memory. I then had the kernel panic, or whatever the soft boot actually is, occur while in Pocket Informant.
I then watched it cycle through display PIN-lock screen, start media scan, screen shut off, and then re-boot seven times, approximately every three minutes while never touching the phone. Some times I saw on the status bar "Media scan completed", sometimes it had the icons.
After powering down, and starting up from off - it is now up again, who knows for how long.
So unfortunately, I can now say this is not just a startup issue; I can also say that something that happens during startup (or at least the kernel launch) creates the conditions for this reboot cycle to occur.
Anyone out there have any ideas?

question what kind of sd card do you have in there as in what class? class 10s can cause issues . wait i see .. have you tried a class 4 or 6? I had mutiple 10s cause issues like this and exchanged for a 4 and all issues went away .. or you can format the card on your computer using fat32 and set to 32k sectors but that did not work for me ..

I had a 16GB class 4 (Patriot) in. I just replaced it with a PNY 16GB Class 10. Both have had the same issues (currently using the Class 10). Both were formatted in the phone itself - so assuming they are FAT32.

[Q] Apps gone

Hi after having to switch my phone off, when I turned it on again it appears that all the apps I moved to the SD card are no longer there. I have just spent some time downloading them from the market again.
Question is why has this happened and how do I stop it from happening again
Thanks in advance

Solution
Hi Nexus.
I think you'll find that the apps still exist, they're just fragmented on the SD
card. This has happened to me plenty of times.
I've found it's only apps that are installed on the SD card and it's never
happened with apps on the phone's internal ROM.
A good way to check is to go into: Settings- Applications- Manage applications-
then tap the SD card tab. That list shows all of your apps installed on the SD
card. I found that when apps here got fragmented/corrupt they didn't show their
original app icon. Instead they showed the stock android app icon. This is a good
way to tell if the missing apps in question are still there but are just fragmented.
The way to solve this, the way that's worked for me, is to plug the phone into a
pc and mount the SD card as a disk. Then on the PC access the SD card via
explorer and right click- properties- tools- then click de-fragment.
This may take up to 30 mins as it's not as fast as a HDD.
From using this technique my apps have always returned and I can use them
with no problems again.
I've also noticed that this issue only happens if I restart or turn the phone off. I
don't understand what is corrupting the apps as the SD card is mounted
correctly and is the one supplied as standard.
I hope I've helped, and I guess this will save you from re-downloading all of your
apps again.
I'm happy to hear anyone's thoughts/suggestions onto why this is actually
happening in the first place too.
Cheers, Dms

Hi thanks so much for the answer. This has been bugging me for ages and even though I have been searching I have not had any joy solving it until your reply.
As you said it only seems to happen to apps on the sd card, and I would like to know why they are not "persistent" There must be a developer who understands the Android system who can explain why this happens and what you can do to make apps you have on your sd card permanent.
As you said it only happens to me when I re start my phone.
Thanks again for the answer

Hi. It's no problem. Yes I havn't seen anything about this issue being mentioned either.
I'd like to know what's causing it. Whether it's a hardware fault or something in the software.
It's a real pain having to hook it up to my pc to sort it out. Especially when I'm away from a pc, I can't use half of my apps.

Moto G3 won't save pictures even with new SD Card.

Hello there, first poster in XDA here. Let me tell you my issue that's been driving me crazy for the past weeks.
I've been using a Motorola Moto G3 for about two years now, running Marshmellow, with a Toshiba 32GB SD Card formatted as internal storage. My problem started a few weeks ago, when I tried to backup my Whatsapp files from internal storage to the SD Card part, and I think something went wrong in the process, since it did, indeed, move my files, but, since then the SD Card would unmount now and then, by its own accord.
I assumed my SD Card went corrupt and tried to save most of my data, but, as I said, it would unmount itself, lasting each time less and less time mounted until, finally, my phone stopped recognizing it. I played along, not being able to save anything else on the phone, since I had no more free space.
The thing is, yesterday I bought a new SD Card since I finally discovered my old one was corrupted, and I formatted this new one as internal storage as well, but now I still can't save save pictures, whether I download them or try to make a screencap. I can still download new apps, but it's quite a pain.
Anyone know how could I fix this?
Thanks in advance
EDIT:
Oh, and to list things I've already tried:
- Tried updating Android version
- Tried shutting down and rebooting a few times
- Tried wiping out data from "External Storage" and "Media Storage" in the Apps section then rebooting

I don't think you understand "adopted storage"... once you make a card adopted (internal) storage, you don't have any external storage, or an sd card from an apps point of view.

Yeah, I know. However, when I go to Settings->Storage, it still recognizes the SD Card. I would show you some screenshots, but then again, I can't save pictures. The thing is. I thought I couldn't download stuff because my old SD card was corrupted, but even with the new one, I still can't manage to get it done.

That's ok, I know what it a looks like.
Did you perform the migration of data in the adoption phase? If not, there should be an option in the 3-dot menu on the storage page.

The thing is, as soon as I moved the files, the SD card started unmounting itself from time to time. I succesfully moved my Whatsapp files, but everything went downhill from there. I don't know if that's what you were asking...

You need a different/better microSD card if that is occurring.
And no, migrate data is part of the adoption process and if it didn't complete then the card isn't being used properly. Once the card is adopted you should not be selecting internal or external storage or moving things, that defeats the purpose of adopted storage.
The reality is adopted storage is garbage, it doesn't work quite as well as we all hoped... Which is why many manufacturers disable it, and most experienced users don't recommend it.
