Hi Rob,

That's because pd v1.05 uses CHS mode to access the drive, and
drives over 8GB report only 8GB as their CHS capacity. To access
the whole drive it needs to be done in LBA mode.

Apply the attached patch to /usr/src/linux/drivers/block/paride/pd.c
to enable LBA mode on large drives. Be careful, it hasn't been
widely tested! Try only with drives that don't contain important
data. If it works for you please drop me a line.
