View Full Version : SCSI travan disappeared

01-30-2001, 12:09 PM
Hi all, I greatly enjoy this forum and have learned a ton...I've been able to upgrade my G3/266DT to no end with your help.

My problem is this - I just replaced the stock IDE CD with a Panasonic/Matsushita IDE CD-RW (CW-7586). I don't have Toast 4.X yet, so it turns out I can't use it, although it shows up in Apple System Profiler. I tried the new Toast drivers for the Platinum 5.0 beta, but also no go. However, I just noticed that my SCSI Seagate Travan NS20 mounted in the lower drive bay has disappeared since the CD-RW's installation. The Travan powers up fine, but won't show up under SCSI Probe, Retrospect, or Apple System Profiler. In fact, and I don't know if this is weird, the SCSI bus doesn't show up at all under System Profiler.

I disabled the Toast beta extensions & double-checked all the cable connections as well as the Retrospect extension - everything checks out. The Travan is ID 2, properly terminated, and the only device on the internal SCSI bus.

System set up is as follows:
Beige G3/266 DT rev. B running basic 9.1 (no fancy custom system software stuff)
20GB IBM Deskstar (main drive bay, master - 0/0)
60GB Maxtor DiamondMax (upper drive bay, master - 1/0)
Panasonic CD-RW (slave - 1/1)
Seagate Hornet Travan NS20 (SCSI ID 2)
3com cable modem
all PCI bays free (using stock ATI Rage Pro with 6MB VRAM total)

Thanks for all the great advice & help (will be getting an xlr8 G4/400 & Miles 2 soon!),

is the Travan terminated?

Yes - thru pins 13 & 14 on the back.

Carefully check the SCSI ribbon connection at the logic board and at the tape drive.

Thanks - I'll check in on that tonight. Can you tell me which door you recommend taking out of the chassis to facilitate cooling? I read this suggestions on one of the accelerator pages, but I can't seem to figure out which door it is - is it one the "hinged upper body" or in the lower part of the case?

the door is on the steel chassis, to the rear behind the lower drive bay.

Thanks for the advice - especially Louie's suggestion. Close inspection of the connection on the logic board revealed that one SCSI pin had been bent out. I carefully used a small plastic tong to bend it back. It's all checked out now.

Thanks for all the help!
