Is there a [reliable] way to use my gazillion SCSI hard disks on my Mac G5
with OS X, say, using a PCI card or a Firewire gizmo? Thanks, PaulN

NFS is fairly reliable once you get past OS 10.3

I have a seven-year-old Intel machine that I bought
for $25 running FreeBSD 4.9 and providing extra disk
space from both SCSI and ATA to the iMac via NFS.

(I did have a Quadra with two small SCSI drives using
AppleTalk over ethernet but I retired it)

I was misunderstood. I no longer have a SCSI machine. I would like to use my
SCSI disks directly on my G5.

BTW, I saw many adaptec SCSI PCI cards. Do they work on a G5?

Thanks, Paul

It depends on the card. Look at Adaptec's website whether there is a driver for
OS-X. In addition, some cards need a Mac specific firmware. Some of these can
be flashed, some not.

I was going to do the same thing, and even bought an Adaptec SCSI
controller card (PCI) when I bought my G5 ... but then decided to bag
the whole thing, since my SCSI drives are so small compared to my 160GB
main drive. Didn't seem worth the trouble (and use of another slot) to
me so I never tried it, so sorry, I can't tell you whether it worked or
not.

Get a card from Atto instead, Adaptec wont support SCSI on OSX in the
future.

"Adaptec is no longer developing SCSI drivers for the Mac OS. Technical
support is available for those products still in their complimentary
support period; however, there will be no new SCSI drivers, firmware, or
patches available."

You may use a SCSI-PCI card from ATTO.

Unless you have quite large and/or fast drives this isn't worth the
effort. The price of a single Mac SCSI controller will buy you at least
160GB of space on one IDE disk that is fast (when compared to
pre10000rpm SCSI drives), quiet and comes at very little power
consumption. I once was a big fan of SCSI on desktop machines but for a
few years now that prices and target market have diverged so drastically
it's just not worth it unless you really need the access time only 15k
rpm drives can provide.
