Hi all, I need to buy a new external HDD for my Time Machine backup. I have a MBA with 256GB drive, so I think I'd need at least a 1TB HD to last me few years. I'll disable the movies folder as it's quite big and I'll sort them manually, but documents, settings, and general files would be included in the backup. Do you have any suggestions for a slim, not too much expensive drive, able to fit alongside my mac in a bag? Another question - would it be possible to temporarily partition the drive? Having 50-100GB free for my use to temporarily store documents or movies in case I'm bringing only my backup drive somewhere, without getting my Time Machine backups messed up?
