Re: Failing Hard Drive, or False Alarms?

And that is my inclination. I've already bought a new drive.
But it really bugs me that running smartctl from the command line conflicts with the automated messages. Which I never got before upgrading to trixie.

A couple of weeks ago I upgraded to trixie.  Since then I've gotten a number
of messages like
Device: /dev/sda [SAT], 8 Currently unreadable (pending) sectors and Device:

day or so of a reboot, but it hasn't been long enough to know if that's a
red herring.

I would take this as a serious warning. Time to get the disk replaced in a
nice, calm, unrushed manner. The disk is *likely* to hard fail within a year.
Do NOT think "I can leave it 9 months", that 1 year is not an accurate
prediction.

Questions:

• how much is your data worth ?

• what will it cost your time to have to suddenly rebuild the machine (prolly
at the most awkward time) ?

Compare these costs to the price of a new disk.


I ran "smartctl -t offline /dev/sda", and the eventual result of "smartctl
-a /dev/sda" shows

which seems to indicate no problems.

I admit I'm not a smartctl wizard, but to me it seems that smartctl is
contradicting itself.

Can anyone help me out?
