2010 MBP with itunes files on a DROBO. I have seen several posts around here and using google, but I am yet to fix the problem. Last week, while starting iTunes, I got the message saying my Library file was damaged and that a new file would be created, (as well as a backup "library (damaged)"). All my podcasts/apps/music were gone, though they were still on the drobo. I tried several things moving the library files around and renaming, but gave up and finally tried "add to library" and pointed it at the Itunes folder. This worked eventually, (it seemed to take all night), and I was left with almost the same iTunes as I started. A few podcasts had split into two lists, but that was a small annoyance. Also, my iPhone has the "updating library" page after syncing every time now, which didn't happen before - the sync finished and the iPhone was available for use straight away. So, apart from that, all fixed then? .....No!! Its just gone and done it again! I am at a loss, as I had no problems with iTunes when I used it with my xp machine, although I did move everything to the external drobo drive, so that may have something to do with it? (I havent just done the transfer, btw. It was done a few weeks ago and seemed to have worked out okay.) It would be nice if someone would help me out here. I don't enjoy using iTunes at the best of times, but this is giving me a headache. I obviously have some issues here, and there must be a reason and a fix for this, I don't want to have to rebuild the library every week! Anyway, thanks for any tips/help you can offer. I will be trying: Deleting the library file and renaming the damaged file. Reinstalling iTunes. Giving up and seeing if I can get back to normal with my windows desktop!
