Try a factory reset. If it still does it, then take it back.

 

Another pebcak error.

 

I had this issue too...problem might be from not unmounting your card before unplugging from PC.

I lost several personally valuable pictures from my big movie shoot this year, very upsetting. Luckily i still have all my more valuable Flip footage though.

 

I could see losing some files, but not an entire card full of data from not unmounting...

OP - did you try connecting your droid to your computer to see if you can see anything on the card that way, or by removing the card and viewing it via PC directly (assuming you have an SD adapter or your computer supports micro-SD)?

There are file-recovery programs that should be able to help you...the files are likely still there, just the directory pointers have likely been corrupted.

Doing a reset (under Privacy in Settings, I believe) is a good idea, in case you have some errant bytes on the Droid that are messing w/the SD card file system.

You also should probably format the card fresh after you're done w/any file recovery actions...good luck. Reminds me I should back up my micro-SD card more often...

 

I ALWAYS eject or unmount any memory based devices before disconnecting them from my PC had to learn the hard way. Hope you get your problem solved.

 

Google it?

 

That wasn't very helpful. Please realize, that as Android based phones expand (some are even hypothesizing dumb/feature phones will get Android), that our user base here will likely get less "techy" oriented. There is no need for a dig like that...Either try to help, or don't say anything...

To the OP, it seems as if you have had several problems with this phone. If it didn't have to do with mounting/unmounting, I would probably take the phone in and have it swapped out before your 30 days expires...

Was it working yesterday? Did you add ringtones via mounting in the last few days? Have you plugged the phone into your computer even if you didn't mount the card to the computer? Do you have any applications that are file managers and less than very commonly used? Honestly I still think its your fault... And your opinions of me mean nothing to me... So I'm an *******. Big deal.

 

Cause what you did you didn't think it was a very big deal and you're not telling us what it was...

I'll try a theroy that might not point to you (but probably still does... ) is that the thing has a FAT file system on it. Try mounting it into a computer directly with a card reader and try doing some file system checks on it. See if you can find bad sectors that may point to a bad flash nugget. If you just find a corrupt file system then its probably related to mount/unmount issues.

You've not rooted your phone have you? I'm going to laugh my ass off if you say you have...

 

So try mounting the card in a card reader and finding problems with the flash array using file system tools.

Just because someone else had the same issue didn't mean you both didn't do something stupid.

 

If you read my post you'll note my saying I'll try a theory that might not point to you. However you were probably too pissed off to read things with a level head.

Perhaps its time to invest in a card reader... You can try to do file system tests while mounted through the Droid but having a card reader removes one more variable.

 

Why do I have to leave... I'm having fun... You're the one that doesn't want the advice... If you don't want it don't ask for it.

Quit whining and try to solve your problem.

 

Well, I had no clue, so I did tap Google:

The problems we encountered generally came from one of three sources. It was either the hardware, the software or an operator error. However, we had a different name for an operator error. We called those problems a PEBCAK error, as in ​

 

this happened to me as well the night that I updated...the card was completely wiped, size on disk returned to factory and all non-standard directories deleted (auto format?)...should it happen again I will take it back...

My 2.0.1 update happened on 12/10 around 1am. Everything on my SD card was wiped, with a new LOST.DIR folder timestamped to 12.10.2009 @ 1:09am. Pictures, music, books, and personal files were all wiped.

I'm trying to recover files, but no luck yet. Verizon gets to hear from me next.
