Quadra 630 PATA: Slave Capable?

[Elfen]

Because the IDE controller on the 68k Macs doesn't implement master/slave.  As has been covered multiple times in this thread.

That's a given. I'm more towards to the question of 'at what board meeting was this decided and why?'

I think CF is a whole other can of worms, but it's related to a bigger problem with the onboard ATA controller.

I'm going to open a separate "CF As A HD" thread on the hack section since it it going to lead away from this discussion of the Q630 PATA. This way we can cover more machines and not just the Q630.

Well alrighty then.

Anybody know of standalone PATA RAID hardware that supports PIO? I know there's internal expansion cards out there, but what about something that operates by itself in a box (save for plugging into an ATA socket for data)?

To add about the blue-and-white G3 and the Power Macintosh G4:

The original B&W G3 does "support" slave drives, but it's often recommended against because it works poorly. The best way to put it is that the second revision of the board "improves" slave drive support and removes an error that could cause corruption if you had a slave drive.

I've never been able to find any reference to any Power Macintosh G4 not supporting slave drive operation, and in fact, my Yikes! G4 board happily ran two IDE devices on each of its onboard IDE channels with no troubles whatsoever.

There are a good number of hardware mirroring options out there. They're all SATA these days, but a SATA to IDE adapter is less than $10 USD. I use several - for smaller machines I have the kind that mirrors two 2.5" SATA drives, and for larger I have the kind that mirrors two 3.5". The mirroring 2.5" are great - they fit in the same space as a single 3.5" hard drive.

They even work great with SCSI-IDE and SCSI-SATA adapters.
