Strange data corruption problem
I don't know if this problem is in fact due to ntfs-3g, but it may be.
I've been running Ubuntu with ntfs-3g. I have a large ntfs drive I use to store media. One day I opened an .mp3 file, and VLC instead played a bunch of snippets of other files on the drive (including video) spliced together.
All the other songs I tried behaved like that, but all the videos--which were in a separate folder--I tried played fine. Thinking some part of my disk must be failing, I ran a S.M.A.R.T. self-test, but it came back clean. Then I ran chkdsk, it returned and fixed some errors, but I read the log and nothing seemed relevant to this particular problem. Tried playing some songs and they were the same. Then I defragged the whole volume and tried playing songs again. Now, instead of playing, say, 10 seconds of video, 5 seconds of the middle of a random song, etc., VLC would play a continuous song, but it was still totally random, began in the middle, and didn't correspond at all to the filename. It's like the hard drive is just putting the needle down in the middle of the record and playing whatever's there.
I haven't done any major operations to half of my drive since the last time I played a song. And my drive doesn't seem to be failing. So something must have silently corrupted the filesystem?
