I recently upgraded my iMac to Leopard, and thought I'd make use of Time Machine. The program told me I'd have to back everything up on another drive, and since I have a LaCie 500GB hard drive I thought that would be plenty (my computer has about 150 GB internal memory). Time Machine told me I'd need to first erase everything before backing itself up, but I didn't want to lose over 3,000 high-quality music files, some of which are pretty rare. I decided to partition the external instead. Unfortunately I didn't realize I wouldn't be able to access any of my music files any more. The problem is probably the filesystem type - the original volume was FAT and the two partitions were formatted as "Mac OS Extended (Journaled)". I KNOW the files are still there, but the original partition table data has been lost. How do I get that back?
