sbconslt, the HDDGuru FAQ says it can support USB if you use a driver to emulate that the drive is SCSI. It also talks about a boot floppy, but I'm not sure what procedure needs to be followed.
"Can MHDD work with USB drives?
A: Theoretically yes. You have to find a driver which turns your USB device into SCSI (under DOS). Then MHDD can work with your device in SCSI mode. The driver is located here: »hddguru.com/content/en/software/
There is also a very good boot floppy disk available here:
dave, when I run chkdsk it often flashes before I'd have time to save it. There is also NO output file saved when it's run on an external drive as there is on the primary drive. So one trick I read aobut was to use chkntfs to force it do the scan of the external scan on reboot in which case it does save an output file. But no matter what switches i tried, I could not get this to work.
I'm only working off of notebooks so my connection options and access is somewhat limited.
The notebook I'm buying is used hence the reason for wanting to DBan and also test the drive surface to ensure it is reliable for backups.
