Hopefully somebody can answer this query for me.
I had a couple of 1TB Seagate discs take their time writing data so I replaced them with a couple of WD drives. One of them is used as a common drive between Windows 7 and linux. The other is the linux system disc. But as they were both installed at the same time, why does one show a power-on hours figure of 76 and the other show a figure of 87 hours?
Is it simply because the common disc is used for both operating systems? If that's true, then this isn't a true reading for power-on hours as although the linux disc isn't being used, it's still powered on.
Oh, and I'm getting the reading for power-on hours from smartctl.

It probably isn't powered on though, when windows starts up it probably takes a look at the partition table and then goes "nope" and puts the disk into standby so it isn't really doing anything. If it wanted to speak to the disk it would tell the controller and it would get woken up again.

Ah. Hadn't thought that Windows would be that clever ;-)
