Is it acceptable to have one SCSI device on the bus switched off, and if
so, where in the chain should it be located?

I am having problems when the devices are all switched on when booting
up, which results in the driver for the external hard disk getting
corrupted, and the Mac then refuses to accept input from the keyboard or
mouse, even when booting with extensions off.

Updating the driver on the external hard disk (Silverlining D2 2.1.1)
temporarily solves the problem, but it comes back after a while.


Details:
PowerMac 7600,  System 8.0
External bus
 Epson Scanner*         device 2
 SyQuest drive          device 1
 LaCie external drive*  device 5
 LaCie CD-R*            device 6

*These devices have switchable active termination.

I've tried everything I can think of... checking the device numbers, and
selecting different numbers for different devices; moving devices on the
chain, swapping cables.

Any ideas?
