True. But if you want to do that, run a long SMART selftest
instead. The problem with the long format is that you will not see
problems the drive could correct. Basically the format-test will not
tell you anything, unless the drive has really serious problems. The
SMART self-test will, as it will also change the SMART attributes. The
drive itself will tell you how long it is expected to take for the
long self-test. Unfortunately you will have to remove the drive from
its enclosure and connect it directly via (S)ATA, since SMART
does not work over USB (the SMART stuff is not part of the USB
storage command set....).
