I suspect that you either have 1) an older, not well-supported host adapter 
r
2) faulty cabling and/or termination.  I have had 0 problems setting up SCSI
devices, SCSI-1 mixed in with SCSI-2, on the same chain (with Adaptec host
adapters) that was not directly attributable to bad/poor cables or improper
termination.  The host adapter negotiates with each device individually to
determine what can be supported so mixing new and old devices is a non-issue.
The catch is that use of SCSI-2 also means shorter cable lengths and active
termination that SCSI-1 doesn't require (but will work with perfectly).
Perhaps ANCIENT SCSI-1 devices may cause a problem (the first implentations 
f
SCSI were far from perfect, based on what I've heard) so removing those may
prevent problems.
There's a reason you were having problems and if you wish to revisit them, we
can probably be of assistance with enough data and facts around the specific
hardware and software (drivers)...
