BTW, I have a "TOSHIBA MK8026GAX" drive. And the response to -B#
settings is really strange. There are two modes:

1. 1-191 and 255 (that's strange!). In this mode 5-8 seconds after disc
access there is a click. I think this is heads unload.

2. 192-254. In this mode there is no click after disc access. BUT! After
seeking to the end of disk (where I have /var part-n) there is a quiet
(but annoying) humming until heads seek out of this place.

If anyone has TOSHIBA drive and is bored please confirm above.

WBR,
YP.
