Hi Chris, John,
The DMA drive has been my primary hope for back up of my G3 PB pismo. I was
+very+ close to getting it running when I had a hard drive failure on my
internal drive. The G4 PB has no bay, right? Therefore, the best idea on the
list was to ftp or rsync to another computer for back up.
The DMA expansion bay drive cannot be the primary drive since you cannot boot
YDL from an external firewire drive. But you can boot OS 9.1 from an external
drive and partition the DMA drive and prepare it.
The next step would be to use "parted" (not fdisk) to divide up the drive as
you wish. Unfortunately, I didn't get a chance to try. Maybe I'll be back on
this when my internal drive is repaired and I get evertything up and running
again..
"Back up is essential"
Good Luck,
perry phillips
