Anyway, it will boot and run fine, just really really slow access to loads of the disc. So no worries I thought, just clone it onto another drive.
But during the cloning process the drive will just dissappear - IO error from whatever tool - dd, ntfsclone, ghost etc.
A powercycle is needed to get the drive working again, but the problem is that no tools will restart from where they left off - even if I just powercycle the drive and it comes back (dmesg shows it coming back on the linux based tools) the duplication tools want to restart again, rather then just keeping on going from where they were.
I have copied all my data off it ok, but there is about 200 apps on the drive installed and working that I am not happy with the idea of spending a couple of weeks reinstalling etc so would rather get the install off in one piece.
Its a vista 64 bit on a 500 gig seagate sata drive.
Any suggestions on other tools that will do the job?
