I had problems cloning a 120 GB ATA/EIDE Seagate drive to a250 GB ATA/EIDE Seagate drive. TI-11 would always indicate a good copy. The result was not bootable. XP Pro would pass the blue boxes 30+ times, then reboot. Afterwards, I tried to a 160 GB WDC drive. No problem at all. Today, I cloned the 160 GB drive to a 200 GB Maxtor. Perfect success. I then tried the 200GB to the 250 GB and it was the same old story. Could it be the 16 MB cache? I doubt it - but I am suspecting that the problem is the Seagate 250 GB drives (Tried 2 of them!) Here is the graphic layout of the finished product on the 200 GB Maxtor. The drive has one partition as shown. http://i91.photobucket.com/albums/k315/HGabbert/200GB.jpg I'm not at all sure as to what the problem is - but it is the only cloning problem I have faced in over a decade. This forum is really focused on backup/restore and not cloning. They are very different.
