and/or cylinder rotating).
Note. The MTBF rating does not represent any particular drive, but is derived from
a large database of test samples. Actual rates may vary from unit to unit.
The mean time to repair (MTTR) is the average time required by a qualified service
technician to diagnose a defective drive and to install a replacement drive. The
MTTR for DAT products is less than 0.5 hour (30 minutes).

the drive to the factory in its original packaging. Contact your distributor, dealer, your
computer system company or your Seagate sales representative to arrange the
return.
