For a number of weeks now I've been getting this notification (only when in Fedora 11 & running GNOME) that "one or more disks are failing".
What do you get for "smartctl --all /dev/sda"? Perhaps a non-zero and
growing number of reallocated sectors?

Uhhh....

To avoid munging by mailer, this would have been a nice attach. Just a thought.


Actually, I got (106 lines of) all this:

$ sudo smartctl --all /dev/sda

That's reasonable, if it isn't growing. But any bad spots are reallocated by testing before you get the drive, so the original count has been zero on my Seagate and WD drives. Don't have anything else spinning to check over the long holiday.

Looks like about twice a day, not uncommon. I don't totally trust POH (#9) as it is sometimes lower than my uptime. I suspect Seagate is reporting in days, yours looks right if the drive is eight months old.

That is really a lot, typically my three year old drives are showing single digits, often zero.

I confess I would not use that drive for anything critical, too much ECC for my taste. Google wrote a paper on matching SMART to failures, and concluded that it wasn't helpful in general. Errors somewhat predicted bad performance, but many drive fail hard without warning.

In looking at my own numbers I just scheduled a drive for redeploy, I have a favorable money to time ratio at the moment. ;-)
