what happened - my SD card formatted itself?

So I get on the train, go into my MP3 player, and none of the tunes there. I check file explorer and the whole 1 gig SD card is blank.
It's a kingmax platinum 1gig sd
What could have happened?

Are you using an XDA1 with a 2003 ROM? I used to get this on mine, it's a bug apparently. Someone suggested a way to fix it, but it didn't work for me, I just kept it write-protected!

I am using an XDA IIi

DID U USE IT INANOTHER PDA DEVICE
if u used the SD card in another PDA device it may cause problems. or if u resart ur PPC a couple of times then it might format itself as well.

I haven't used it in anything else, or even taken it out. I reset the machine occassionally when it hangs...
Thanks for the replies, I'm still not sure what happened, but it hasn't happened since, so fingers crossed

Hi. I have a SanDisk 1Gb SD card. Something very similar happened to me. Several times.
I felt quite sick the first time this happened but here are some things I have discovered.
1. It's a good idea to copy your entire SD card - lock, stock and barrel - to your hard-drive, or some other storage medium. (Er...except an SD).
2. Your card may not have formatted itself - try this: remove the card, (I blow on the metal contacts for luck,) replace it, access |Start|Settings|Today|Items, then alter the Today Timeout value on the Items page. Exit to the Today screen. Check your card using a file browser (File Explorer is OK for this).
Sometime this is enough to force your PDA to read the card.
3. Sync with your PC using ActiveSync (assuming you have this facility). Find a lightweight installation file that may be lying around undeleted on your pc and attempt to install it to the storage card. You may get arsey messages from ActiveSync or from your ppc saying it can't be done. You may not. You may even have to soft-reset your ppc BUT you may find that your Storage Card contents have *miraculously* reappeared!
WEIRD!?! But it has been said that truth is stranger than fiction.
4. It may be that after all this tinkering about the contents of your Storage Cards still reads as nada. Consider doing a proper format of the card and copying back the contents of your Storage Card that you, with great foresight, copied to your hard drive on your PC.
Or consider blowing out your card manufacturer and asking for a replacement.
Regards, The Gog.
PS Please don't ask me why this often works. Obviously it is magic, quasi-magic or SD is short for 'Satanic Devilry' and your data is possessed.

Gold card / SD Card not responsive. HELP!

Tonight my 32 gb lexar micro sd card which also happens to be the gold card I rooted my phone with became nonresponsive. The phone tells me there is no card there, I put the card in my card reader on my computer, I can see the files but I can't retrieve the data from it. If worst case scenario happens and I have to try to reformat the card and consequently loose all of the photos, memories etc on the card, what happens to the gold card when reformatted. Will i beable to unroot the phone if I need to take it in. Does anybody have any ideas because I can find nothing and am just a little panicky.
Thanks!
Edit: Okay, I panicked, sorry. I see that I should have taken this to Q&A, and I have since found a thread that said that the gold card is not needed to reverse the root. That said, does anyone have any ideas as to what I can do to save the card and the info on it? Has anyone had this issue with the SD Card suddenly being not recognized?

Actually, yes, I think there have been some users that have gotten that issue. Do a search for it in the general section and you should find the appropriate thread. The last time I saw one of those threads was a couple months ago.

I format my gold card once in a while it does not delete the gold card status but does delete everything on it. What I do is I create a folder on my laptop and copy evertyhing on it to folder then I format it. Place it back in phone and let it create the folders it creates then I just copy the pics and music back on to it. As far as the apps are concerned I have to redownload them all which I keep a list of on notepad in my computer. But I also like to reflash the ROM as well to start all fresh with the phone before I download the apps. But this is what I do there might be an easier way out there just search if you dont like my method. Good Luck

The problem I fear I am having is that I think the card has failed. Took 9 hours to copy the pictures back to my computer off a class 10 card. It won't eeven let me copy the whole card.

Are you trying to copy files from card while in the phone or out of the phone. Sorry the best I can come up with is the way I do it above. There is a program out there called h2testw_1.4 that I use to tell me if my SD card is a fake or damaged cause I use ebay often. It writes to the card then reads it back and tells you if written files were corrupted then tells you if card is damaged or fake. The only issue it takes a really long time to run the process, I ran it on my 16gb and it took about 4 hours before I got my results back but was well worth it. It also advices for best results card has to be empty. So maybe it may be worth he wait to copy files to computer unless files are there already and you can just reupload them after format and test. But again on a 32gb may be an all day process.

I took the card out of the phone and used two different card readers. When I left the card in the phone, the card was not seen by my computer.

Okay, I can't save the card, but I can slowly save some individual files if I let them copy overnight. What are some must-save files that I should try to salvage if I can?

I usually save only my camera pics and ringtones. When you format card and place back in phone it will create the needed folders so I dont worry about that part. Also like I said I always do a full wipe, reflash rom and start all fresh with redowloading apps. Any purchased apps you can get from market and redownload free since already purchased. I know its a pain but patience is a virtue.
When you format card run the h2test on it hate to see you throw away a card that might be good and its an app or file on it issue thats giving you the grief.
Question: Are you mounting and unmounting card to phone thru Settings>Storage?
Also are you placing sim card cover back on before seeing if phone is reading SD card?

yes, cover is back on and i do the mount/unmount. i had just completed a nandroid backup, it rebooted, and the sd card was no longer there, nor fully available on my computer thru a card reader. where do i get the h2test program? the only upside, is it was a new lexar card with a 10 yr warrany, but it will take up to 21 days to replace. but you are right, patience is a virtue.
thanks for the reply

Just Google h2testw_1.4
If you cant find it let me know I'll Megaupload mine for you.
Good Luck

Thanks for your help, but nothing could get into that card. I'm sending it back. Frustrating. At least I saved the pics

[Q] Cannot delete or add to SD card

A few days ago, I tried taking some pictures with my Droid Charge and the pics would not save. I tried in the stock camera app and in CameraZoom EX. CameraZoom gave me an error message "failed to save photo to SD car (error code=2). I figured I was out of space.
My Titanium Backup scheduled backup did not run the next day. So, I assumed I was out of space.
I connected the phone to my PC and deleted some pics and music. WHen I was in WIndows explorer, it said I had about 2 GB free after doing all of this.
When playing music today, I noticed files that I had deleted before still present on the phone. I thought this was weird. I went back and checked and all the stuff I thought I deleted was still there.
I searched on the CameraZoom EX error code 2. It directed to remove and reinsert the card and reboot. I tried that. I have tried unmounting and then mounting with no success either.
My phone seems to be working fine, but I cannot delete or add anything to the microSD card (the original that came with the phone). It does not matter if I use my WIndows 7 laptop, desktop, or various file managers on the phone itself.
ANy idea what is going on?

To me, it sounds like the SD card is going bad. Not a common occurrence but it can happen. You're lucky you can still read from it... I would suggest getting a new SD card (Verizon might even give you a new one free) and copying your data to it before sectors start going bad. By the way, how did you manage to full up 32 gb?
Or I could be blowing this out of proportion and it's just a matter of write protection on the card.

Another option is to copy everything off the SD card, format it, and try to write everything back. Sometimes a format can joggle a bugged card.

It is mostly music that I have on there. I am not sure how write protection would have gotten on the microSD card or how I would remove it. It does not have a physical togge like an SD card does.
I think I may have to try re-formatting. Ugh.

Corrupted SD card. Call VZW and be nice on the phone, explain the situation, hopefully they send you a new one.

Hmmm, this is interesting. I cannot even format the microSD card. I tried to do it through Windows Explorer. It looked like it worked. I then tried to copy files back on and it choked halfway through on a movie, I think.
Anyway, what was more interesting is that when I looked at the drive again, everything was back where it originally was. So, the re-formatting must not have actually worked.
I then tried to erase the SD through the options in Android. I unmounted. I then selected Erase SD card. After rebooting (to just be safe), the SD card still is untouched.
THis microSD card has become an impenetrable force. More realistically, it must have write-protection enabled somehow as that is the only thing I can think of.
The question is how do I find out if write protection is enabled and how to disable it? Any ideas are appreciated. Thanks.

[Q] My external SD files keep corrupting after loading them in my phone!

I have always used micro SD cards to help store all my music and pictures and such, however earlier today after copying some music over, my files weren't being read by my music program Zplayer. I assumed maybe it just read wrong, so I unmounted it and then mounted it again. After this however, it still was not being read so I cleared my app data and restarted my phone. After again not reading my files, I put my SD back into my computer to check and realized that my Music and Photos folder were missing. :crying:
After looking around a little, I realized all files on my SD card disappeared but my LOST.DIR filled with unreadable files. I have used this same 32 GB SD card before so I do not understand why this is happening. Now after reformatting my SD card using my phone AND computer, when I put only one album on it worked perfect. I tried adding a few more after that, and it worked as well. I assumed it was back to normal so I added all the rest I had on my itunes library and then put it into my phone.
After the previous two successes I was disappointed to see that my phone stopped reading my music files again. I used ES File Explorer and saw that my music folder WITH the music files were still intact and in their correct directories. I tried to play a song using the built in ES player, and it played perfectly, so I tried just unmounted and mounting again, thinking it might fix it.
Again still nothing was read and I looked at my file directories and a message popped up saying something around "sd/ext_sd/Music was not found" and discovered once again that my files were missing and my LOST.DIR folder had again been filled.
I am at a lost now as I can not figure this out and I am scared that any information I put on my card will be ruined. No messages pop up warning me my card is corrupted, my files just disappear after being put in my phone for some reason.
TL;DR Whenever I add files to my SD card and put it in my phone I can see the files but they are not read. After unmounting and mounting them again all the files keep moving to the LOST.DIR folder even after reformatting.

SD Card broken?
Maybe the SD card you are using is broken. Is it old? Can you try with another SD card?

This issue happened to me on my PSP memstick which i figure out that it was unmounting issue from the PC, I simply unplugged the usb without safe removal which really shocked me

The weird thing is that I bought this SD card about a week or two ago. I use another SD card for another device and I have not had any problems. My current one just started corrupting everything after I added more files last night. Also I do not use the USB cable, I unmount the card from my phone then use a SD card reader to copy files, not showing any issues!

Try The corrupted SD card on another phone if you can. Yet it highly possible that it is a bad SD card (damaged during the shipping or whatever)
