There are very good reasons NOT to use DD mode if you use certain types
of Adaptec SCSI controllers - they simply won't boot from DD.
Aside from that, FreeBSD needs to have *one* recommendation for disks,
anything else creates too much confusion. It is certainly my impression
that the recommendation has been NOT using DD for the IA32 architecture
for quite a while now.
(The other day a coworker of mine wanted to use DD for some IBM DTLA
disks, because he'd heard that the disks performed better that way -
something to do with scatter-gather not working right unless you used
DD. I'm highly skeptical about this since I have my own measurements
from IBM DTLA disks partitioned the normal way, ie. NOT DD, and they
show the disks performing extremely well. Anybody else want to comment
