About 2/3 of my MP3 library is corrupted. Some of them are really quiet, some have a delay in them (ie same sound played again a moment after the original) and some have a weird high pitched warbling noise in the background with heaps of distortion, like they were encoded at a really low bitrate. The only thing I can think of that I've done differently recently was to defrag the drive they're on with Norton Speed Disk.
So far this problem shows up in OS X QT Player and iTunes, with all other apps closed. I haven't tried any other players or OS 9.
Is there some way I can recover these files?
