[comp.sys.mac.misc] Grievous SCSI Problems

rroberts@magnus.acs.ohio-state.edu (Ross Allan Roberts) (05/11/91)

I have a friend with grievous set of problems concerning her mac and the
various SCSI perherials she owns. She has a Mac SE/30 w/40HD, an ADS 105
(both Quantum PS OEM's), an Chinon CD-ROM, and an HP DeskScan (?)... the 
flatbed scanner. THe problem is she can't hook them all together at once
without some serious bizarre things happening. They are hooked together like
this...

Mac (internal 40)<=====> ADS 105 <=====> Chinon <=====> HP Scanner
7          0               4               ?                2       -- SCSI ID#

The problem is twofold... first, the line will not recognize both the scanner
and the CD-ROM at the same time... either one or the other. I smell a SCSI ID
conflict, but can't be sure as the CD-ROM was temp. on loan to someone else
and wasn't there. Second, when anything is extended from the ADS, the INternal
40 is 'lost,' and can only be force-mounted using the SCSI Probe CDEV. Areal
pain in the ass when the Internal40 is the System disk. Everything is set right
, the startup CDEV is set... all I wonder about is Termination on the HP, but
she says it's terminated. If anyone has any suggestions, email is preferable, but not required. Thanks for your help.

I've also encountered SCSI questions when hooking up a Chinon CD-Rom but it was
easily solved by changing the order of the devices. Try the CD-ROM last (or
first.) This solved my problem.

Hope this helps!
