The "scu" utility, which is available for both NT and linux
environments can change the blocksize - and scads of other parameters
on most SCSI disks. It's powerful enough that you can brick a drive
if you're not careful ;)
I used to buy NOS Tandem SCSI HDD dirt cheap because they had a weird
blocksize that would make Windows/Linux systems barf. I would then
use "scu" to change the blocksize parameter of the drive to 512 - and do
a low level format. Then I'd have a "standard" SCSI HDD for a fraction
of the price of a "standard" drive.
Of course you could change the blocksize of a drive to 576 - or
anything you wanted - and then do a low level format for that blocksize.
You can pickup scu for NT and linux (including help and summary pdfs)
by anonymous ftp to my website via certain browsers or:
ftp bickleywest.com

cd scu

You'll need to put something together that can talk to the raw
scsi interface and issue your own read commands. Are they common
command set drives?
Should be. I don't believe CompuServe did anything too silly.

576 or 2304.

Can it read 'em at any blocksize too? Read is far more essential than write.
