Damaged SD card!!

I don't know when did this started happening actually, I flashed a number of roms in the past couple of days, but I can't get rid of this stupid notification and its really driving me crazy!
When I mount my SD card so I can transfer files from PC and the unmount I get the error "Damaged SD Card - SD card damaged you may have to reformat it"
The thing is reformatting does not solve it, and when I have this notification nothing that accesses the card works (music, photos, astro..)
I tried reflashing my rom again which made the error go away for a while but after some mount-unmount I have it again!
I have a non-branded HTC magic (32A) with Cyanogen 4.2.3 and Enoch theme and RA's recovery image and NO apps2sd
Any help?
Thanks

fixed it
Okay I got it to go away, I formatted from the recovery menu (fat32 only)
and I turned off the swap file and uninstalled the swapper app.
No problems so far!

i've found that rebooting the phone makes the sd card damaged error message go away
and that rebooting my pc actually solved the problem of the pc not seeing the sdcard
but that may just be temporary, i dont know

Strange SD Card!
When I mounted my SD Card I was receiving an error and was asked to Scan or Continue. I chose scan and then it looks like it mounted fine. I can view all the folders and files but if I try to copy any files to the card or try to create a folder I get an error saying the Drive is not available and it is no longer mounted. I put the card in a card reader and I received the Scan option again and I scanned it to fix any errors but it doesn't find any. I then can copy, delete and modify anything on the card. I put the card back in the phone and mount the card. No issues until I try to copy, delete or modify and it unmounts and will not work. I have the original T-Mobile Rom and I have not rooted it.
Any ideas?
Thanks,

Using SD card from Rezound in the S5

Sorry guys, I am traveling right now and my wife needs a bit of help.
She took her SD card out of her Rezound and put it in the S5. She is trying to figure out where everything is stored as when you look at the SD card (when its plugged into the PC) its not showing all of her files?
Basically she needs to move music over and when the SD card is in she cant find anything on the phone. Is there a new format that needs to be used or does anyone know why she wouldnt be able to view the entire contents of her SD card while the S5 is plugged into the PC?

bump... I am having this exact same issue.

KitKat changed how apps can access the external SD card so if you just swap a card into a KK device you will probably not be able to access all existing app files with same apps you had on the old device. When you plug it in to the PC however I'd expect that you can see everything (unless some files are hidden for some reason). So maybe her music was on the 16GB internal storage of the Rezound?
File transfer is fast on USB 3.0 so just format the card through the new phone (Settings> Storage> Format SD card) and transfer it back over. I usually create a "Music" folder in the root of the SD card and dump whatever right in when it connected to PC... I just did this on my S5 a few minutes ago and the phone saw the music when I started the Music app.
I'd consider it good practice to format the card when changing phones anyway.

SD card suddenly no good??

Hey all, I'm hoping somebody can help me. I'm currently running a rooted stock S5 I have safestrap installed and towel root.
All of a sudden this morning when I open to my gallery and pressed on a picture, it would not get bigger. I didn't think anything of it so I rebooted my phone. And when it came back up there was nothing on the SD card, all of my pictures and my music has disappeared. I unmount the SD card pulled it out rebooted we mounted SD card and I got an error message saying that the SD card was blank or the files are not supported. Has anyone come across this before?
When I got home from work, I pulled the SD card out put it in a card reader and on my computer again there were no files at all on the card. I put the card back in the phone and tried to reformat it, it would not reformat. I tried with several different SD cards and I'm getting the same error message saying that the card is blank and the file is not supported.
Any help would be greatly appreciated.

you might wanna try minitool partition wizard on your pc with your micro sd in your card reader and plugged into your pc and when you pull up your sd card im sure youll see your sd card isn't fat32 anymore and is Linux so to fix youll need to right click on the sd and click delete then put back into your phone and format then youll have it working again, but sorry to say your files are now gone on your micro sd

Locked out of encrypted files

So I bought the S7 edge popped in my SD card and encrypted It. The card was giving me some issues so I backed up my files on my Pc formated the SD card and reloaded the files (MP3s) now when I go to play many of the songs they don't play and just say "sorry unable to play file type" it's odd because about half of the songs do work any ideas for fixing this I have a quite a large music collection and it would be quite pain staking to have to download these one by one again

Would encrypting them and decrypting them help?

Really none of the brilliant minds here at Xda have any idea?

Did you copy the files off with the SD in a pc reader or via mtp from the phone? I would guess the the base encryption key data is different since you reformatted the card, it would make sense to me because otherwise there would be no point to supporting SD encryption.

SD in a pc reader. Is there anyway for it to read the files again?

If Google did their work well, not likely.
I don't know the details but the only consumer hope would be with the card inserted in the device that formatted it as theoretically the encryption of the SD card should be done with private key data that is tied to the device it was formatted within (in addition to whatever private data you provided such as a PIN). Otherwise it would be too easy to just move the card to another device to decrypt the data.
I've seen some references to the Android SD card encryption *not* necessarily encrypting media files (music, movies, pictures?) so it's possible those files were not at all encrypted - which is substantiated by the fact that you can play SOME of them.
It may be that the files that don't play are, unfortunately, simply, corrupted data and not encrypted at all. ;^(

I had the exact problem, it seems to be some issue with a lot of S7's from from my research online. After almost giving up after a few weeks I finally did find a fix which hopefully will work for you and anyone else who has encountered/ will encounter this problem. Here are the steps I took:
1. After the sd card became unresponsive on my phone after encryption, I transferred all my files from the sd card to my PC. I had to do this via the sd card slot on my laptop as the card was not being recognized when connected via the phone.
2. I then formatted the sd card on my PC. For those not familiar with the process just right click on the card in "my computer" and select format then quick format.
3. I then reinserted the card into the phone to make sure it was recognized, then removed it again, inserted it into the PC and transferred all the files back over.
4. I went into my phone under security settings and changed lock screen security to "none" while leaving fingerprint on.
5. I put the sd card back into the phone with the files. They won't be accessible as yet since they're encrypted but the next step is to go ahead and encrypt the sd card. Wait however long you have to, for me it took less than a min. After this go back and decrypt the sd card, let that process run through then the files should now be decrypted and accessible. If the sd card goes unresponsive again just try again by formatting the sd card and putting the files back, this time maybe a few files at a time.
If this method works for you I would suggest backing up your data frequently and staying away from encrypting the sd card at least until samsung/android release a fix for this issue.

Disappearing files in MicroSD Card.

Greetings,
I transferred my Pictures and music from my old SanDisk ultra 64GB micro SD card to my new Samsung Ultra + 128GB card. My first attempt at loading the data was through the restore function on the LG Bridge app from my PC. 3 day later when the restore was finished the phone indicated that the data was corrupted and had to be formatted. The second time I got a "file Corruption" message on my SD card when I was transferring files while both cards were in card readers. The next attempt was with the old card in the card reader, and the new card in the device, with the device connected to my laptop directly by USB, the end result being the Corrupted file message (again). My most recent attempt is by downloading files from my PC to my device card. Now the files are gone when I restart the device. The Music file in my folders are gone but the music outside of the folders are still present. All my pictures on my card are gone as well. ANY help is desperately needed and appreciated!!!

Did anyone have an answer to this? I'm having the same issue with my V30 - the files I copy to the external SD card by any means (AFT, SyncMate, FTP, SyncTunesMac) disappear...

I don't have good news for either of you that sounds like the sd card or the card port are going bad. Is it possible your ad cards are counterfeit as in does this behavior happen with another known good card...
I would try the following
First backup anything you can
Try a known good card that works in other devices and see if the behavior persists if yes
It is an issue with the phone not the card if the behavior stops you both got bum cards be more careful where you buy amazon is not even safe.
If the behavior persists try resetting the phone full factory. If custom Rom reload the rom. If the issue persists past that you most likely have a hardware issue that requires mainboard replacement.

Also try uploading files to the cards using the computer(with the micro sd to sd adapter) and check if the files stay(using the phone)

I had a similar issue with Moto G Turbo with Lollipop. It permanently damaged 2 MicroSD.
I ended doing a factory reset and MicroSD worked correctly again.

Counterfeit

By the above description, this is almost certainly a counterfeit sd card.
Google "H2TestW_1.4.zip" to test ANY card you buy before you ever use it.
It's a solid, lightweight program that does its job well.
Anything that says it will do the job better / faster is blowing smoke up your skirt.
