Yes, the disks are identical, in the sense that it's the same brand, type and size.

Before i dare trying this, i need to be 100% sure about something.
HDD #1 is the primary slave and #2 is the secondary master.
I think that means that #1 is /dev/hdb and #2 is /dev/hdc, correct?
And how about error handling? Can it ignore bad clusters and/or read errors?
Oh, and overwriting HDD #2 is exactly what i want, thanks for the warning though.

I'm really scared to screw this up as you can probably tell, so please forgive me my insecurity and apperhensiveness.
