Firstly, the B&Ws used the IDE interface for the hard drives, not SCSI -
IDE busses can only ever have two drives, a master and a slave. Compared
to SCSI, it is a terribly nonscalable interface that was born in the
overly price-competitive Wintel market to cut costs. I suppose IDE does
a decent enough job these days, but no surprise that SCSI still
dominates in all high-performance markets!
I haven't heard about the problems with a B&W not recognising a second
IDE drive, but just in case you might want to check the 6 gig drive and
make sure it's not in Cable Select mode because this will have it claim
the whole IDE bus. It's a jumper setting, as Reg says you're best going
to the website of the manufacturer to get a listing of jumper settings.
That, or just use the 30 gig drive set as the Master with no 6 gig
drive... it's only 6 gig after all ;)
And the other thing you can try, if you don't have an internal Zip
drive, is to connect the second drive up (in Slave mode) to the
available connector below your CD drive. This was always a great kludge
to get a third drive in your G4, and the CD drive will definitely not be
in CS mode.
Best of luck getting it to work!

If both drives have same number then the computer doesn't know which
one to boot, so it doesn't boot, in my belief. That knowledge is
gained from putting 2x IGB 'Phil McGree' SCSI drives in a 7220 here
recently. Eventually my son's girlfriend's father (a Fujitsu Systems
Engineer) told me to go to the IBM website for instructions on
changing SCSI number jumpers, as they were IBM disks. That I
eventually did and heypresto it started!

Hi Reg:
Our problem is we can't even get the machine to start up with the drive
connected. I guess I will have to do without Simon's old 30 gig hard
drive
:-(.

Have you given it a different number? I know with SCSI drives you
need to set a separate SCSI number or it won't be recognised. I guess
IDE would need that too as all drives need separate numbers. Try
using a program called Mt.Everything on the Mac to see if it can see
it. If you like I can email you a copy.

Hi
I am trying to upgrade Nathalie's B&W G3 with a second slave drive
(Western
Digital 30GB, 5400rpm). She currently has a 6GB master drive
(Maxtor).
Despite all efforts I cannot get the machine to recognise either
drive when
both are hooked into the IDE cable. However when the 30GB hard drive
is
taken off the IDE cable the machine starts without a problem.
The 30GB drive has come out of my PC. I have been to the Western
Digital
web site and it says that these drives should work with Macs (as a
slave
drive) and as a master drive (when installed by Apple at the factory).
The drive currently has a Windows and a Linux partition on it (but I
don't
see why this should matter). I just want to be able to recognise the
drive
and then format it.
I set the drive up as slave and then switched to cable-select. The
same
thing happens.
Is 30GB too much for the B&W G3's. That is about the only thing I
can think
of?
Regards
Simon
