I have a Quad core AMD cpu, 16Gb RAM & run W7 64 bit. I backup to an external USB2.0 2Tb drive.
W7 is genuine (passes the validation test) but I don't have the original disk or even a sticker with serial number. The supplier has gone bust so I can't rectify this.
I run Windows backup with all the default settings applied & let Windows decide what to backup.
My problem is the backup hangs. It backs up the files OK, but when it starts to create a system image, it stalls at 57% every time. I think it used to backup OK (& nothing has changed) but I've never need a system restore to check this.
It starts at 2.00am so I'm not running anything else at the time.
I have been running Samsung Drive Manager in the background to backup files to a different external disk, but switching this off makes no difference. Ditto BackUp Maker has been switched off.
I've tried different USB ports for the backup drive but no change.
I tried a Windows backup to a new 3Tb drive but had problems with sector size (4k?) but I understand my 2Tb drive shouldn't have this problem.
Can anyone help please?
