Sup guys, I occasionally lurk here checking for some solutions to a few problems... however, recently I didn't see anything about my latest situation on these forums. This may be old news to a lot of you, but maybe it'll help someone. Anyways... story time. I work for a corporate VZW... We got our test Galaxy Tab unit in a little while back, and as you can imagine, I was psyched. It's pretty nice I'd say... hopefully it'll be a little more polished by launch date... although I'm afraid I might be hoping too much. It's a little glitchy and our unit had a malfunctioning camera and the browser had a good bit of lag. ...Anyways, I wanted to check out some video, but our test unit had no video available on the SD disc. I just happened to have a ton of it on my SD card in my DX. A quick battery pull and I popped that bad boy in. A media scanner popped up on the Galaxy Tab and I waited. I had a weird feeling, and a few minutes later I opened the gallery. No pictures. I opened every conceivable application and even went into the file browser searching for my videos. Nothing. Nada. Zip. Damn... Oh well... Must be a bug... So I popped my card out and put it back in my DX... Rebooted... and suddenly realized that the Galaxy Tab had wiped my card clean (except for my .mp3s for whatever reason). The thing is, I take a TON of pictures... and backup occasionally... but as things go I still lost a LOT of pictures and videos I really wanted... Luckily... as I discovered accidentally about a week later... any corrupt file on android gets put into that handy LOST.DIR folder on your MicroSD disc. I could see the thumbnails in the file browser on my droid X, I guessed and a quick batch rename of the file extension got me the vast majority of my lost files back. I still have a lot of files in here that aren't showing up after a quick rename. I've tried .jpg and .3gp... I can't really think of anything else to try. Any ideas as to what else they could be? It also uninstalled a few apps I'm assuming were on my SD card.... games mostly. I lost all my progress in Angry Birds dammit. tl;dr -> Lost files? check LOST.DIR and rename.
