My post scriptum seems to have made it out, but not the original message. I'm trying again. ------- Forwarded Message To: freebsd-hackers@freebsd.org Subject: IOMega ZIP drive experiences Date: Wed, 07 Jun 1995 20:20:40 -0700 From: Mike O'Brien <obrien@leonardo.net> I realize everyone's totally frazzed with getting 2.0.5 out the door by now, but I want to get this out while the experience is fresh. Tuck this one away and read it when the CD-ROM is cut, unless you're hot to trot. My IOMega ZIP drive arrived today, so of course I immediately plugged it in and ran it under DOS to make sure it had survived delivery. Seems to work just fine under IOMega's DOS toolkit. Well, it's a SCSI disk, after all, let's boot 'er up under 2.0R and see what happens. At first I booted up without a disk in the drive. This is what I got: Jun 7 19:42:22 caern kernel: aha0: 1542C/CF detected, unlocking mailbox Jun 7 19:42:22 caern kernel: aha0: reading board settings, dma=6 int=11 (bus speed defaulted) Jun 7 19:42:22 caern kernel: aha0 at 0x334-0x337 irq 11 drq 6 on isa Jun 7 19:42:22 caern kernel: aha0 waiting for scsi devices to settle Jun 7 19:42:22 caern kernel: aha0 targ 0 lun 0: type 0(direct) fixed SCSI2 Jun 7 19:42:23 caern kernel: aha0 targ 0 lun 0: <QUANTUM EMPIRE_1080S 1220> Jun 7 19:42:23 caern kernel: sd0: 1029MB (2109376 total sec), 2874 cyl, 8 head, 91 sec, bytes/sec 512 Jun 7 19:42:23 caern kernel: aha0 targ 1 lun 0: type 5(readonly) removable SCSI2 Jun 7 19:42:23 caern kernel: aha0 targ 1 lun 0: <TOSHIBA CD-ROM XM-3501TA3054> Jun 7 19:42:23 caern kernel: cd0: cd present.[331448 x 2048 byte records] Jun 7 19:42:23 caern kernel: aha0 targ 5 lun 0: type 0(direct) removable SCSI2 Jun 7 19:42:23 caern kernel: aha0 targ 5 lun 0: <IOMEGA ZIP 100 M.29> Jun 7 19:42:23 caern kernel: sd1(aha0:5:0): illegal request Jun 7 19:42:23 caern kernel: sd1 could not mode sense (4).

This time, things got a bit further: Jun 7 19:46:49 caern kernel: aha0: 1542C/CF detected, unlocking mailbox Jun 7 19:46:49 caern kernel: aha0: reading board settings, dma=6 int=11 (bus speed defaulted) Jun 7 19:46:49 caern kernel: aha0 at 0x334-0x337 irq 11 drq 6 on isa Jun 7 19:46:49 caern kernel: aha0 waiting for scsi devices to settle Jun 7 19:46:49 caern kernel: aha0 targ 0 lun 0: type 0(direct) fixed SCSI2 Jun 7 19:46:49 caern kernel: aha0 targ 0 lun 0: <QUANTUM EMPIRE_1080S 1220> Jun 7 19:46:49 caern kernel: sd0: 1029MB (2109376 total sec), 2874 cyl, 8 head, 91 sec, bytes/sec 512 Jun 7 19:46:49 caern kernel: aha0 targ 1 lun 0: type 5(readonly) removable SCSI2 Jun 7 19:46:49 caern kernel: aha0 targ 1 lun 0: <TOSHIBA CD-ROM XM-3501TA3054> Jun 7 19:46:49 caern kernel: cd0: cd present.[331448 x 2048 byte records] Jun 7 19:46:50 caern kernel: aha0 targ 5 lun 0: type 0(direct) removable SCSI2 Jun 7 19:46:50 caern kernel: aha0 targ 5 lun 0: <IOMEGA ZIP 100 M.29> Jun 7 19:46:50 caern kernel: sd1(aha0:5:0): illegal request Jun 7 19:46:50 caern kernel: sd1 could not mode sense (4). Using ficticious geometry Jun 7 19:46:50 caern kernel: sd1: 96MB (196608 total sec), 96 cyl, 64 head, 32 sec, bytes/sec 512 This time, trying the 'dd' just got me: dd: /dev/rsd1c: Device not configured I couldn't read a disklabel either, same error. Of course there isn't one, but it didn't get that far. Another interesting point is that the IOMega toolkit lets you mark a diskette as 'non-removable', presumably so you can just use the whole thing as a sort of oddball hard drive. Whatever 2.0R does in attempting to probe the device obviously convinces the ZIP drive that this has been done, because pressing the little button does not allow the diskette to be ejected as long as UNIX is running. I was hoping that a SCSI disk would be a SCSI disk, or at least close enough to let me back up my system (I'm the guy who's always whining that his Colorado Jumbo 350 doesn't work under UNIX either). Apparently not. So 2.0.5 is going to leave me to back my system up on lots and LOTS of floppies, but what the hey. I'll be willing to work with anyone who thinks they can figure out what to do to the SCSI driver to get the ZIP drive working, either before or after 2.0.5. Oh yeah: the multimedia tour of the drive under Windows is a hoot. Somebody was having too much fun, especially in the sound department. Mike O'Brien ------- End of Forwarded Message
