Good work.
Please let me ask silly questions.

(1) About what "target" means
I guess "device" means writing to device files directly
(--filename=/dev/mapper/ioband1)
and "directory" means mounting these device files and writing to some directory
on the filesystem
(--filename=/mnt/ioband1/test.dat, I'm assuming mount /dev/mapper/ioband1 on
/mnt/ioband1),
am I wright?

(2) Conditions  in RDF sheet
Conditions in sheet "RDF" and "RBF" are same but results are slightly different.
Should "Mode" in RDF sheet be "Direct"?


Regards,
Muuhh
