I have this really weird problem a 32gb SD card I just got. This is for my car, so it will only have music files, mainly MP3s, on it. The first two folders I copied onto it function just fine. Total is under five gigs. They have folders within folders within folders.
Then the next few folders I copied came out empty. There was nothing in them when I opened them, and I can't delete them because Windows says the directory isn't empty.
I tried copying again, a folder at a time, and they came populated. BUT the files won't play. WMP says the file type or codec used to compress the files isn't readable/available. Some ---steaming pile of meadow muffin--- like that. But it isn't WMP, because I put it in my car stereo and those folders were plain inaccessible. The files of the first two folders that do play on my computer were accessible and played on the stereo.
So, back on my computer, I moved the files to the main directory of the card. Then they played on my computer. ?? I put them in a new folder, and they won't play again.

I really need a folder structure, cos I have way too much different stuff.
- UPdate: I took the card out of my computer and went back to the car to see if maybe after re-copying a third time they were accessible but just not playing on my computer. Nope - folders still inaccessible. BUT GET THIS: come back in and plug the card back into my computer those re-copied folders that DID have files on them DON'T NOW. They're ---smurfin--- empty. I betcha I can't delete 'em, though....
Nope, can't. But the disc 'properties' says it's almost half full, so apparently
something's on it.....
