That is correct. I have more than once had my fingers in PC's which could
not read MS-DOS 320K disks, not to speak of 160K.
Assuming the PC in question could read 360K disks, and assuming the
320K/160K disks you were trying to read were undamaged, can you please
explain how this can be a _hardware_ problem. I can understand that the
BIOS might not support single-sided disks or 8 sectors/track, or whatever,
but I can't see how the hardware could have problems with it.
As I understand it, Imagedisk talks to the bare metal of the disk
controller, so is not hindered by BIOS limitations.
