Time machine back up with iMac 27

by ananth_tp / March 29, 2012 12:04 AM PDT

I am using iMac 27 with Lion Mac Os 10.7.3.

I was using a hard disk for time machine back up which was working fine till the internal hard disk crashed. After replacing the hard disk I was able to restore the system back to normal using the time machine back up hard disk. On reconnecting the same hard disk for continued back up, the system hangs. Even erasing the backed up data and a fresh attempt to back up using time machine also does not work. The system hangs after backing up for some time. I have excluded the hard disk problems by connecting another hard disk.

Has any one come across this problem? Any solution for this problem?

Not personally, but I have heard of it.

Solution is usually to reformat the HD, using Disk Utility, as Mac OS X Extended(journaled) with the Option set t GUID.

look in Activity Monitor

What do you mean by "hangs"? Does it require a reset? Can you look in Activity Monitor and see if the CPU and HDD are intensively used? Maybe spotlight is re-indexing, and you need to leave it for awhile.
