There was also a fix in there to keep the motor from being activated during the probe for people who do not have tape drives. I re-sent this fix to Rod a couple of weeks ago but I'm not sure what he's doing with it. The fix within ft to avoid the messages works, but the correct way to remove them is to get them out of the fd driver in the first place. In my opinion they should only be debug messages, since it's not as if the user can take some corrective action after seeing them. It would be nice if someone did this before 2.1 is burned. Also, a number of people have reported to be having problems with the driver recognizing their tape drives. They sound very much like timing problems. At one time the timing characteristics of the driver worked for almost everyone as long as your CPU and bus speed was not on the extreme in either direction. It seems with PCI and/or pentium systems this may no longer be the case. Has anyone examined the DELAY (microtime?) function to see if it is running noticeably faster on those systems? - Steve steve2@genesis.tiac.net
