I woke this morning to find my library drive (1 TB external drive), holding 33,000+ tracks, audiobooks, over 1,000 videos (tv and movies) clicking and whirring with a disk failure. mounting it seemed ok, then it would reset making the mac shout at me for "not unmounting properly" This drive is now knackered - so I've lost all that media. I've recovered some tracks off other machines using homesharing, pulling what I can back into a fresh library on a new disk, I've also used iExplorer to copy music and videos off my iphone, and redownloaded my itunes purchases - but only a 5th of what I originally had. I'm gutted. - Should I invest in iTunes Match in case I lose my local library again? - As I get promo tracks from music labels for my music podcast, will these get updated once the album is released on itunes with Match? Your thoughts please.
