I don't think the stardrive device actually Forbid()'s all that much. It just busy waits. Since the default priority for the handler/device is 5, the two are easy to confuse. Following Matt Dillon's suggestion, I added the line "Priority = 0" to the mountlist entries for my stardrive partitions, and the perceived performance of the system improved a whole lot. Of course, now the hard drive can get locked out by anything running at priority 1 (which I tend to do a lot), but so far that's been a minor annoyance at worst. MicroBotics really ought to fix their software, but they seem to have a pretty dismal record in the software department. Their hardware is ok, but... -Dan Riley (riley@tcgould.tn.cornell.edu, cornell!batcomputer!riley) -Wilson Lab, Cornell U.
