It is apparantly caused by the drive telling the SCSI adapter that I've changed the platter, in the hopes that the adapter will tell the driver and the driver will refresh it's notions about what is spinning there. Of course 386/ix does *not* do this ... it just prints the message. I have no idea why your disk should be sending this SCSI signal, though. If I had to guess, I'd guess that something like a power or logic transient was causing your disk (or maybe the Adaptec card) to power down/up occasionally. ----------------------------------------------------------- loc@tmsoft.UUCP (Leigh Clayton) uunet!mnetor!tmsoft!loc
