Not directly, but you /can/ set block/fragment sizes in the disklabel
editor, which newfs honours if within bounds: enable [X]pert mode
and modify/re-creat
I don't know about installing on USB, but the copy to/from FAT ( -t

I hope it's just a typo in your email, since rsd1c is the whole disk and
will erase any partitioning table you previously created.

One likely culprit is your system's BIOS, that likely reports only USB

dmesg? results of testing with dd?
What speed to do you get if you use FFS?
I get around 9 MB/s to a slow USB hard disk with FFS, which would be around 2.5
hours for 72 GB, and I routinely backup many GBs to it. So I'm guessing either
its ext2 or your hardware.

What does "slow" mean?
It means that compared to other OS's.
Which OS's?
Yes, it hurts: the penguin.
