thanks for your report.
The raw value of Power_On_Hours attribute (5957) does not
correspond with the information of the self-test log
(97 hours) however.
Is the last self-test a recent one, i.e. did you submit a "smartctl -a"
just before you sent your report? Or is your drive indeed almost
6000 hours "old" and the last self-test has happened a long time ago?
As far as I know, older Fujitsu disks report attribute 9 in seconds,
newer ones in hours, so I need your input.
