I want to move my slave IDE drive to a PCI card like Sonnett Tempo, but I can't reformat the drive. Can I do this? The drive is currently a slave. Can I boot from the PCI connected drive then? OS9 AND OSX?

It probably won't change anything on the drive, but you'd better back it up fully before you try it.

The "drive" is the Mac partition on the hard disk, and as long as the hard disk mechanism/controller is recognized by the expansion card, it should work fine.

You'll probably have to change the jumper on the drive though, to master, but that probably won't change any of the parameters of the "drive."

I say this having swapped IDE drives in and out of Performas and Power Macs AND windows machines without losing data -- but there's always a first time. Back in the old days of RLL drives in XT-class machines, and with AT machines too, you had to have the same controller (or a cousin) to keep from having to reformat. The IDE standard is pervasive enough, though, that you don't have to worry about problems most of the time.
