Its quite possible that smartctl might not be accurate on an old drive like

It is a laptop, or I would have thought of that (I hope), seeing how difficult it is to obtain ATA drives.

Perhaps older models report values from the controller and not the disk itself, but also it is common for there to be some discrepancy in the UNITS used for storage


smartctl reports the age as thousands of hours for my Maxtor/Hitachi/Fujitsu
disk , yet it is only a few days old

On recent disks, Maxtor has started to use Attribute 9 to store the power-on
disk lifetime in minutes rather than hours.
In this case, use the: '-v 9,minutes' option to correctly display hours and

Some models of Fujitsu disks use Attribute 9 to store the power-on disk
lifetime in seconds.
In that case, use the: '-v 9,seconds' option to correctly display hours,
minutes and seconds.

AmonLanc:~ # smartctl -v 9,minutes -A /dev/sda | grep Power_On
9 Power_On_Minutes 0x0012 056 056 000 Old_age Always
- 323h+45m
AmonLanc:~ # smartctl -v 9,seconds -A /dev/sda | grep Power_On
9 Power_On_Seconds 0x0012 056 056 000 Old_age Always

Hum... that could be right, seconds :-?
Five hours sounds correct. But other values are also wrong:

4 Start_Stop_Count 0x0012 094 094 000 Old_age Always
- 10256
12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always

193 Load_Cycle_Count 0x0012 099 099 000 Old_age Always
