[ale] Weird SCSI Drive Compatibility Issue

[Jeff Hubbs]

I recently picked up an Adaptec AHA-2940UW/B Ultra Wide card and I've
connected a CD-RW drive and a 4,2GB Seagate ST15230WC Fast Wide drive
(specs at http://www.seagate.com/support/disc/specs/scsi/st15230wc.html)
to the card's internal 50-pin connector in preparation for a Gentoo
install, booting from the aforementioned CD-RW drive.  

The CD-RW drive appears to work fine and the drive has worked fine
before connected to the machine's built-in narrow SCSI controller.  I
believe that I have termination all squared away and I have set the
AHA-2940UW/B to a max rate of 20MB/s as per the specs of the ST15230WC
drive.

The problem I'm having is that after the Gentoo CD boots and lands me at
a shell prompt, fdisk /dev/sdb (the ST15230WC) shows me a 32MB drive -
CHS = 31,64,32.  When fdisk starts, it does say "Warning:  Invalid flag
0x0000 of partition table 4 will be corrected by w(rite).

Is this just a drive/controller mismatch that I just shouldn't have
attempted?  I've never had a SCSI drive situation go this weirdly
before.
