Subject: [G] Moving hard drive from ATA controller to built-in
controller
System: Beige G3 with SIIG Ultra 133 ATA PCI Card. OS 9.2.2
I had a hard drive bootable from the built-in ATA controller. I
installed a new drive on the SIIG card, intiialized it, then copied
the
system from the built-in drive to the new add-in drive. I removed the
built-in drive. Then I booted from the add-in drive and it worked
great
- quite a bit faster too.
Then I took a shot at updating the SIIG firmware, but it failed. So I
tried hooking the SIIG drive to the built-in controller, but it was
not
recognized. Is this expected? Is there a way around it?
Yes. The formatting scheme for the built-in IDE controller is
different from the scheme for the IDE controller card. You must
re-initialize the drive to move it from one interface to the other. Of
course, re-initializing destroys all data on the drive.

Not true. The definition directly from PC Magazine:
(2) (Integrated Drive Electronics) A type of hardware interface widely
used to connect hard disks, optical disks and tape drives to a PC. IDE
was always the more economical interface, compared to SCSI. Introduced
in the mid 1980s with 20MB of storage, capacities increased a
thousandfold in less than two decades.
With IDE, the controller electronics are built into the drive itself,
requiring a simple circuit in the PC for connection. IDE drives were
attached to earlier PCs using an IDE host adapter card. Subsequently,
two Enhanced IDE (EIDE) sockets were built onto the motherboard, with
each socket connecting two drives via a 40-pin ribbon cable for CD-ROMs
and similar devices and an 80-wire cable for fast hard disks.
Admittedly this is from a PC rag, but they were the first to use widely
use IDE drives. I've moved IDE drives from several different machines
over the course of my computing history with nary a problem. The
interface card is just that, an interface from the motherboard to the
drive, but the controller itself resides on the drive. Perhaps the
on-board controller is bad? HTH
