It is recommended that SCSI devices with power off also meet the
bus loading characteristics required of devices which are powered.

However, I know from my own experience that some early drives did
not conform to this. I had problems with some drives of around
50Mb 3.5" size (I forget which manufacturer). If your 163Mb drive
is quite old, then this might be the problem.
