I noticed some files in my iTunes library (located on a MyBook Live 2 TB) had their information greyed out (meaning I couldn't change it). Checking them in Finder I saw that they were Read Only. I tried changing - no luck (not enough permissions apparently). I tried changing it through Terminal - no luck there either. But there are no problems moving them or deleting them through Finder, I just can't use iTunes to change anything. If I use TuneSpan to move a file from the NAS to the internal hard drive I can make changes. If I make the change in iTunes and then send it back to the NAS using the same app - I can continue to make changes in iTunes. But if I do the same thing without changing anything, the write protected permission goes back into play... Sometimes, if I completely remove the album for example, and re-add it, it'll have the correct permissions... It's all very strange, and I have no idea what might be the problem. I doubt the drive itself is corrupted, since this only happens with files that iTunes moves to the drive. Also, since I'm able to move, delete and rename files and folders through Finder, but not through iTunes, I'm certain that it's iTunes that's the problem. I've reinstalled iTunes, and I've tried starting a new library - but this keeps happening. I can't really find a lot online either. Does anyone know anything about this?
