I have a Ubuntu server I'm loading up with (used, pulled from other systems) hard drives for storing downloaded files. I've been using smartctl to test each drive before I start using it.

One of the drives looks like it may be ok, or may be messed up. It only has 1 reallocated sector, which is probably acceptable for files I can afford to lose, as long as it doesn't increase.

The weird thing is that I get some seemingly random data from the SMART output, particularly for Head_Flying_Hours:

240 Head_Flying_Hours 0x0000 100 253 000 Old_age Offline - 231966888734858

That's 26 billion years. That can't be right! And it's increasing quickly...20 minutes later it read 170,192,374,116,491 hours - 19,428,353,209 years!

The other data from SMART stays stable and at first glance looks reasonable for a somewhat older drive.

Is this a firmware or smartctl bug that I can ignore, or a sign that this disk has some serious issues? If money werent an issue I would just trash it, but if its otherwise ok it would be fine for storing files I can afford to lose.

Other drives in the system all seem to report normal smart data. I havent tried putting it in a windows system to test yet.

    Time to junk that piece of hardware old man.. – Firee Nov 14 '14 at 10:25

Seems that you installed newer firmware CC1H (14-15 series uses it by default) which uses msec24hour32 format for that attribute. Try smartctl -v 240,msec24hour32.

The drive is definitely old but looks fine from the limited information you have presented.... You reallocated sector count is only 1 which doesn't appear to be a dying disk. power up hours is 45195 is what I would use here (which is about 5.2 years).

BTW, 1.5 TB disks are not really all that expensive these days (easily < $100).

Normally, I'd get a new disk and not worry about things.

  • Easily < $100 heck; they are less then $50 in most cases. Considering < $150 are 3TB+ drives – Ramhound Dec 1 '14 at 11:58
