Here's how it is probed: (ncr0:6:0): "IOMEGA ZIP 100 L.27" is a type 0 removable SCSI 2 sd1(ncr0:6:0): Direct-Access sd1(ncr0:6:0): ILLEGAL REQUEST asc:24,0Invalid field in CDB sd1 could not mode sense (4). Using ficticious geometry 96MB (196608 512 byte sectors) I erased the disk that came with it on a macintosh (Otherwise you couldn't write to it, even with dos or FreeBSD). It seemed to work fine with the disklabel automatically generated by FreeBSD. I had to address it as /dev/sd1d or something. I could eject the disk, mount and unmount, etc... with no problems. Now that I wrote a disklabel onto the disk, it only lets me mount the thing when I have just booted, but when I unmount it and try to do anything with it again, it says "medium may have changed..." and then gives me "device not configured" messages when I try to access any of the /dev/sd1* devices... (i.e. I can't mount it again until I reboot) Otherwise, it is nice. Has anybody else seen this kind of problem with a removeable disk???? I get ~700 K/sec with my NCR 810 scsi controller with iozone creating and reading a 32 meg file... Any ideas??? Is there a bug in the code that re-reads the disklabel when the medium is changed???
