I've been having a lot of issues with my time machine drive lately. First it would get stuck on preparing backup, so I decided to reformat it. Now when I try to back up my computer, it gets to about 2gb backed up and then it says it failed. I tried going into the disk utility to repair the disk, but when I click repair, its as if the hard drive ejects from the computer, any ideas? Is my hard drive dead maybe? I've had it one month short of two years.
