Have a 750 GB hdd from a Toshiba laptop that has 8.1 factory installed on it.  Suddenly the machine is booting to the hdd failure is imminent message.  I can then boot to the desktop.
I attempted to clone this drive (with DP) to a new 1TB drive.  there were no errors after 20 hours of imaging.
I inserted the 1 tb drive into the Toshiba laptop and reset the bios settings to boot without secure boot etc.  The PC will not boot.  I then tied the win 8.1 CD in recovery mode and there was no GPT partition.  I took the drive to a Win 7 machine and there is no GPT partition. the larger empty partition claims to be RAW.
I used a data recovery tool to see if there were files and there were.  I could see the structure and the users, windows program files folders.

What went wrong?  Can you no longer clone a drive plug it in and have it bootable with Win 8 and GTP??

All DiskPatch does is make a sector by sector copy of a disk. If the clone is different from the original, then there should be a reason for that. maybe the disk got worse while copying. can we see a support analysis logfile for both disks pls?


Please note, that even if all sectors were copied an OS may refuse to boot after cloning (sector-by-sector). Disk imaging and cloning software meant to backup and upgrade disks (Ghost, True Image etc.) often do additional stuff, depending on the operating system on the disk, to make sure a disk is bootable after it was cloned. Maybe something as simple as a 'disk signature' not matching. Don't have Windows 8 here, can't try this myself. DiskPatch is purely meant to make exact disk copies. It does just that.

Kind regards,
