Not on an IDE drive it wouldn't.

It appears that the EZ135 is reporting bogus geometry information.  I just
spent $1500 on car repairs, or I would have bought one (a SCSI one though)
some time back.  I believe that both types incorrectly report their size.

I think it's a historic f*ckup in the EZ135 firmware that was carried over
from the SQ3270.
