What's causing my folders to become corrupt on my SD card? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Problem:
I'll connect my phone to my computer and open the SD card (32gb) to view it and several of the folders names have been changed and they all start with a "u" now (see below for example)?? On top of that, everything in those folders is now missing... There is also a new folder called "Lost Dir" with a bunch of files in it with just numbers for names, no extension though. I'll delete the folders and they reappear on the next restart..... So I usually end up reformatting the SD card and it's good for a few days and then does it again.
Example:
Downloads is now uownloads (with a funky symbol next to it)
Data is now uata
TWRP is now uWRP
ect...
This has been happening for a little over a month... with different ROM's, so it's not a ROM issue. Could it be Fast Charge?? Could it be the kernel I'm using as I always use the same kernel?
Anyone else have this problem that could shed some light on it for me? I'd like to figure out what is causing this so I can fix it, or not repeat it.
Thanks, Jason

Sounds like the card is failing, or the controller is.
Try reformatting it in your computer using a USB adapter, not a built in reader. Do a full, not fast, format.
Could also try running Scandisk.
What brand card?
Obviously, trying a different card can sort this out quickly.

Bad card. Is it a 32GB card by chance?
Formatting will only be a temporary solution. Eventuality the errors will pop up again

Yeah, 32gb SanDisk.
All signs are pointing to this, I'll probably pick up a new one this week.
Thanks for the replies!

You may be able to have the card replaced for free under warranty.

using old microSD card

i know this is probably a simple problem with an even simpler solution, but why is the EVO not recognizing my card? it's got some of my contacts, but none of my other data is there. does the Droid (the phone i came from) use a different directory or something?

Contacts aren't usually stored on the SD card unless you're using an unusual app. I (and I believe the majority of Android users) store our contacts in the cloud (Gmail, facebook, etc).
Could you be a little more specific on what data you're missing?
i'm missing literally everything on my SD card. music, apps, data, etc.

Can you read the card in a card reader? If so, you could copy the data to your PC, format the card, install it in the phone and then move the data over via USB.
seemed like a good idea, but didn't work.
is everyone sticking with the included 8 gig, or is no one else having problems switching?
No trouble here with my 16GB card. Maybe it doesn't like how your card is formatted? Try copying everything to your PC, reformatting the card, then copying everything back.
**hah.. just saw the post above suggesting the same thing. I didn't see any mention of what format you used, though.. mine is FAT32.

I'm using my 16GB card from my hero...no problems reading it here. I assume you've also tried reseating it (And double checking you are seating it right by making sure you can read the included 8GB after seating it again too)?
I used the 16 gig I had in my Moment and the Evo evowned it. Maybe the card went to pisser early and right on time but now it is broken.
Had to order a new one.
I would say format first.
i did format it; no fix still.
this sucks, man!

[Q] Android.Process.Media taking too much CPU / Battery

Hi guys
My Note 2 seems to be using too much CPU process. I have Watchdog task manager installed and almost every few minutes, i see Android.Process.Media getting a warning. At the same time, i can feel my phone is hot.
I've did some research on the web and it seems to suggest that there's a corrupted sdcard or corrupted media file (mp3, jpg, mv) in my sdcard. Thus the media storage keep trying to check the files.
My situation is, in my SD card i only have 1 folder that has a lot of pictures (download through mangawatcher). No mp3, no movies. The root folder has a .nomedia file, but it seems that the media storage still craws through the entire folder.
My phone is not rooted (need it to stay unrooted due to some reason). Is there any way to fix this?
1 other possible way i found was completely disable Android.Process.Media, but if i do this, my ringtones and notification tones are all gone (goes into unknown state).
You could try backing up your SD Card to computer, formatting it (FAT32 if external) then restoring folder by folder to isolate which one might be causing the problem?

Yeah, that's what i'm trying now. Will update here on the result.
Latest update: It would seem that my problem could be related to a bad microSD card. a friend of mine who suffered from the same problem said her problem was solved once she changed SD cards..
SanDisk -> Kingston.
Another update: i'm getting this error now..sdcard unexpectedly removed
I read some other forums, it seems to suggest the error could be because of corrupted SD card (SanDisk)
http://forums.androidcentral.com/verizon-galaxy-note-2/231647-sd-card-unexpectedly-removed-2.html
Might be worth doing a full read write test on the card on a computer just to be sure.

Works wonders... too bad had to use root. I'm using a 8gb MicroSD now, will try with my SanDisk 32gb again and see what happens.
Yeah that's one way around it, it's a bit annoying as a band aid fix though as each time you add any media like photos it will require triggering a scan. I also had issues with installing Apps remotely from the browser using that method.

Many thx Good to know that.
I just put back my original SanDisk 32GB. Though i don't have the media scanner problem, but i do see from time to time it says "Preparing SDcard" i suspect my SD card is dying just like the rest..
Had the same issue with my S3.
Turned out that the SD card was dying, which caused to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the media scanning process.
I creates an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card, and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
Please PM me if anyone needs this app.

[Q] Phone freezes when trying to access photos on ext. SD Card

I have 812 pictures in my Camera album on my external Toshiba 32GB Class 10 SD card. When I first got the phone in December, everything worked great, even after transferring from my EVO 3D. Now, whenever I try to access my stuff on my SD card through the Gallery app, it just freezes. I can hit home and exit the app, but back doesn't work and I cannot scroll anywhere. I can still access pictures via ASTRO and save stuff on to it..I just don't anymore, in case it goes corrupt. Any solutions? I tried searching, but no one seems to have the same problem as me..
Lol. Sounds like a simple cache issue with the gallery. Go to settings, application manager, all apps, find gallery, try clearing cache, and if that doesn't solve the problem, delete data. This will not delete your images. I think it may or may not delete your thumbnails. Just scroll over the images again and a thumbnail is remade. Nothing will harm your photos.

hmmm... I would normally say that the 800+ images in one gallery might be the cause of the problem. But you say that it was working fine previously. Even then, I'd recommend to split the images into different folders (maybe based on month they were taken) to minimize the amount of thumbnails that gallery has to process and look through.
I'm assuming you've done the MA6 and MB1 updates. Perhaps upgrading the phone to 4.1.2 caused this? I haven't heard of anything similar on XDA, but I'd stick with kkarson's approach and clear cache from the gallery app. Hope that works for ya!
Already tried clearing the cache and data from the Application Manager, but still the same results. I have a folder of old camera photos from my EVO 3D with 1780 photos in it, and it opens and I can view the photos perfectly fine, with no lag or freezing. But when I open the "Camera" folder on the ext. SD card, it just freezes and I have to go back to the home screen. I just upgraded to MB1 today and still the same results..

Maybe there's corrupted files on the SD card causing the phone to choke when it tries to read them. If you have windows 7 or XP you can put the card in your pc, (with a card reader or usb card reader), then right click on the card and choose properties. Select the tools tab in the properties box. The first option is error checking which will scan the disk and fix errors (if fix errors is checked). However, if there are corrupted files on the SD card it might be going bad and should be reformatted.
I have the same issue. I havent found a fix. I even formatted my external SD card.. didnt help.

No fix. Your Sd card is done. The fix is get a new one.

The card isnt that old and isnt giving any read/write errors.
I guess that could be the case.. its a class 10 Sandisk card.. I would think it would last more than a couple of months.

I'm looking at a Sandisk 32GB class 10 ultra card that I got right after xmas so it's only 3 mopnths old. It started spitting out corrupt files after only 1 month. Eventually I'll get another card. But if my phone ever random restarts, or suddenly locks up, or I notice media is using a lot of battery, I know if I run scan disk on the card it will show errors. It lasts for a few weeks between formats.
There are also tons of posts from people that have had sd card failures on this phone (also with new cards).

Dont worry you're not alone, theres a thread in general that had a ton of posts and the thread title was "If your sdcard failed on you, what recovery were you on?"
Many have had to purchase 2 or 3 cards until they got one that didnt go bad or corrupted. If you got the sdcard (the one that failed) very recently, you could call the manufacturer and tell them it failed on you, I'm sure they would send a replacement because I've seen others do it and they got their replacements in a timely manner

Micro SD Card mount problem

Hey folks, I have a bit of a problem here. I just recently started having this problem of my micro sd card not being able to be mounted to my GS3 for anything. I don't know what the problem is nor how it can be rectified? So it's known, I'm rooted with the latest CW recovery mod for JB fw version 4.2.1. I tried recovering to factory settings but that doesn't work because I have wiped all my caches. Any ideas as to what I can do to fix this issue? I have no problem losing full, permanent root access by the way but also keep in mind that I currently do not have a computer of any kind. I was able to gain permanent root access when I borrowed my buddy's laptop last week but gave his laptop back.
The message I always see on my phone when I go to manually mount my SD Card in Settings is ..."Your SD Card is ready to be removed."

Honestly, this sounds like your SD Card is in its last days, so to speak. This happens quite frequently and they just do not last forever.
What brand is it?
What is its class and size?
How old is it?
Where did you buy it?
If you boot into CWM, can you mount it there?
Your best bet is to try your best to get any important info off of it, then format it. If you have the space, copy everything important to your Internal SD, then format it through the settings menu. If that doesnt help, you will need to try again from a computer. Use the SD formatter tool from http://www.sdcard.org
I am assuming the card was working fine on your phone and this just started happening recently.

The SD Card is a legit 64GB, Class 10, micro SD Card that I bought not even a year ago from Amazon for $55. It's the card that looks half red and hald grey. I had a ton of stuff on it too... movies, about 2k songs, tv show series, hundreds of pics, paid-for apps, emulated games and more. I think once I flashed a new different rom from the original regular CW 4.2.1, that's when my card was wiped clean. Now I can sometimes go to my sc card in the EZ Explorer Android app and it shows that my card has no files on it whatsoever.
Oh, I also get an error message of something like "cannot mount sd card... error." .... when I mount my card in the CW Recovery screen. I've also tried adding new files to the sd card and when I go back later that day or the next day, those files were wiped clean like they were never written to the card.
So now, the only place I can save files to is my internal phone memory.
So sad and blue...

Yup, sounds like its on its way out. Unless you specifically tell cwm to do so, it doesn't touch your external sd. Some people have made the mistake and wiped out their data by not paying attention to what they're doing.
Anyway, there are data recovery tools you can try to use. Many people have had some success recovering info off of flash memory like that.
Sounds like it was a sandisk, but it should be clearly labelled as such. If its not its probably a knock off. Youd be surprised how many fakes are out there. Even highly reputable sellers have been known to sell cheap knock off sdcards. They don't do it on purpose of course, but I've even seen where they came from stores like Best Buy. The last time I looked I think Samsung, Kingston and Sandisk were the most popular targets for fake sdcard dealers.
This is why I only buy Samsung brand cards, and only from sellers who are Samsung Authorized Dealers. They buy direct from Samsung so you can be confident that you are getting a real one.
Even so, the best ones are still known to fail. I'd google for flash memory data recovery to see if you can rescue some stuff. And I would replace the card.
Its always a good idea to keep a backup even of your sd data. Sorry for your troubles.

When you get a new card, there are ways to tell if its a fake or not. You will have to search them out as I really don't remember, but just so you know, the info is out there.

Camera images never saved, disappeared from gallery.

To make a long story short, I took some irreplaceable pictures today that disappeared.
I have my camera saving to my 64gb memory card. I took a few pictures and a couple of panoramas and they ended up showing up glitchy and useless.
They didn't appear in the gallery with the exception of a few images.
It looked odd.
I rebooted the phone and tried to go into the gallery and they just weren't there. The previews showed up momentarily and then they vanished.
Now when I try to take a photo to go to my external memory, it works fine. It didn't pre-reboot.
Is there a method of:
A: Recovering my lost 10-15 images.
B: Ensuring that this doesn't happen in the future.
For the record, my card seems to be working fine. Music on it loads up quickly as well as any other images that I loaded onto it. Files open and there is zero lag. I don't suspect that the card is corrupted or anything.
Thanks guys.

You could try something like Recuva: https://www.piriform.com/recuva

I'm unfortunately on a Mac. Guess I'll boot into boot camp and install it and give it a go.
I hope the pictures actually existed as files though and not some cached object.
Update:
Overnight, the saving issue arose again. I'm forced to use internal storage when using my camera.
I've seen this problem before. So SD cards don't work well with Samsung devices. I bought a Samsung SD card and never seem this problem again. I recommend you do the same.

I'm using a SanDisk 64gb. Guess I've gotta dig up some cash and get a Samsung.
I don't see how this is an issue though.
What is your card formatted in? My current is in exfat. I'm thinking the format may be an issue.
It may be a kitkat issue. Google "kitkat SD card write". Root users are using a fix that sets permissions so the sd card can be written to by all apps as expected.

Right before I came across your post, I found some info on the kitkat issue with sd cards. I'm guessing that's what's causing this problem. Odd because it's the default Samsung camera that's messing up.
Oh, how I miss root. I just hope we get root soon. I'm pretty close to selling this phone and hopping on Tmobile.
I had this problem happen with very VERY irreplaceable pictures, on my backpacking trip to china, one of the most irreplaceable pictures of my entire life was taken, appeared glitchy in gallery, phone reset and it was gone.
after taking out the SD card, and doing many deep scans to try and recover the deleted pictures, it seems the pictures arent there, which leads me to believe it somehow tried to save it in internal memory (which cant be mounted as a drive, so cannot be recovered).
if you can somehow flash an older version of android (like 2.xx) you can mount your phone as a drive, and then attempt to recover deleted data from your internal SD..
yeah all i can say is ,,|,, you samsung.
I too have the same problems as the OP. And I am on SAMSUNG micro SD card! Guess it is one of those first batch gremlins?
However, I think the problem has gone away after I switch on the image "preview" option. Give it a try.
I had the same issue with a 64gGB SanDisk micro SD card. The camera would seem as if it was taking pictures but nothing was actually saved; they just shows as corrupted files in the gallery. I lost countless irreplaceable images from our honeymoon because of this. Once I switched to a 32GB Samsung micro SD card I never had the issue again, also saving the pictures directly to the internal memory solved the problem. I use the SD card for music as well so it has to be something with the phone writing to the SD card. From what I've read it's a issue with the compatability with samsung and non samsung sd cards for some reason.

Never had this issue with any of my Samsung phones (S2, S4, and now the Note 4). I'm using a SanDisk Class 10 32GB. I'd recommend pulling the files off the SD and doing a format. Download the App SD Maid as well for routine maintenance on your SD. Good luck.
My 64GB SanDisk SD card was giving unexpected unmounted errors, so I picked up a Samsung 64GB SD card. The unexpected unmount errors went away, but now I have this problem. Pictures are not saving to the SD card correctly. Sometimes it says media not found. Others the preview/thumbnail looks fine but the full view is just grey.
I am going to try saving to internal memory and manually moving to the SD card as I run out of room.
