Well, I did the entire drive with:
   dd if=/dev/zero of=/dev/sda bs=512 count=10 count=8388314
and that worked fine.

I also tried your
    dd if=/dev/zero of=/dev/sda bs=512k
and that worked too (8192 records in, 8192 records out).

So... dd works, (c)fdisk doesn't. I guess I could just get someone to 
partition a blank hd just the way I want and then send me their 
partition table (dd if=/dev/sdX bs=512 count=1 | gzip -9 | mail ....), 
then I could dd it on this end and I'd be all set, huh?

Well, there's another option. I could plug the drives into a SCSI card 
on a PC... but I've tried that, and I can't get that to work. If someone 
wants to help me with *that*, I'd appreciate that as well, since I 
clearly don't understand all of the intricacies of SCSI, because I 
couldn't get the PC to recognize the drive(s). I *think* it had to do 
with the drives being (apparently) "single-ended"... but I don't know.
