CCC or Disk Utility to clone a Mac HD of one new iMac to another, over ThunderBolt, we are getting I/O errors. Even though the clone fails, the destination  system does boot and log in, however, the logins take a very very very long time.

When using CCC (Carbon Cophy Cloner) or Disk Utility to clone a Mac HD of one new iMac to another, over ThunderBolt, we are getting I/O errors. Even though the clone fails, the destination  system does boot and log in, however, the logins take a very very very long time.

Thoughts.

Edit: Already ran Disk Utility. Also reinstalled a fresh OS on top of the cloned OS and it seemed to remedy the problem. Then, cloned to next machine in the row of the lab. Same problem.

iMac, OS X Mountain Lion (10.8.4)
