To run a HDD through an ATA card you must format the drive through the ATA 
card. I've been doing some reading on this as I'm thinking about getting an 
ATA card for my Beige G3DT 266. HTH

Yes, that's one of the disadvantages of these boards.  The system sees them 
as scsi.  You can't just take a drive off the native ata bus and hang it on 
the ATA card (not most of them anyway.)  You need to reformat it.   A bit 
time consuming and messy.

The ADTX card, made for Apple and intended to provide 1 GB drive capacity in 
its SCSI-based PowerBooks, is the one adapter of which I am aware which does 
NOT require reformatting as a SCSI drive.

IOW, you can take your EIDE/UATA drive which was initialized by Drive Setup, 
plug the ADTX card onto this drive, and the combo will be immediately usable, 
as a SCSI drive, of course, without re-initialization.

There is an 8 GB limit in the ADTX firmware, and even though "ADTX" is a 
valid SCSI device in Drive Setup's tables of supported drives, this support 
is apparently functional only if the attached EIDE/UATA drive is itself 
equipped with Apple firmware. This may be the one case where an Apple logo on 
an EIDE/UATA drive actually means that the drive itself has Apple firmware, 
and was not simply a standard drive made for Apple on contract.

It is my guess that the requirement to reinitialize an EIDE/UATA drive for 
use with the many PCI-based cards, all of which simulate a SCSI card, and, 
thereby, cause the attached drives to be seen as SCSI drives, comes from the 
old 8 GB limit, and from a conscious decision of the original ACARD [ * ] 
development team (FirmTek ?) to go for a non-standard way of attaching drives 
in order to break the (artificial ?) 8 GB limit.

[ * ] The first such card was designed and made by ACARD, but was sold under 
the ProMax TurboMax Ultra/33 name, on an exclusive basis.
