Do you have some suggestions as to how I should go about dealing with this? Other commands to test the hard drive? Kernel parameters? Anything?

Check if it's a bad sata cable. These errors usually indicates a broken cable, connector or a bad disk. But if there are no bad sectors I wouldn't bet on the disk being broken.

Thanks, Morten

I will check the cable.

I'll give it to you, unless you are bigger than me, of course - I only fight men who are smaller than me and who pose no threat ;) Thanks, Morten

Uncorrectable Errors with specific LBAs are usually a very solid indicator for a defective drive.

If you could share the full `smartctl -x /dev/sda` output, we might be able to establish/identify some further hints on a failing drive instead of a bad cable.

I include it below. It says "Device Error Count: 12". Oddly enough, the command sudo smartctl -t long /dev/sda completes without any errors at all. The problem is also intermittent. It is rather odd.

This indicates the drive is running rather hot, I suppose it is enclosed in a laptop with poor ventilation and there is not much you can do about it? However, if you can, a bit more airflow would be appreciated by the drive. But in case you are going to replace it with an SSD (in contrast to the current SSHD), these tend to create less prolonged heat and should run cooler.

It is a Lenovo M93p ThinkCentre which is indeed not in a very well ventilated place.

Since these errors are not UDMA/CRC errors (which might be caused by a defective cable) and only occured very recently (error timestamp in relation to Power_On_Hours) a faulty cable seems very unlikely if you did not recently poke at it (e.g. reconnected/reseated the drive for whatever reason).

In my opinion this drive is on the brink of failure and should be replaced immediately.

OK, I will heed your advice. Too bad, I just installed Arch a couple of months ago and I have set up a really nice system. Now, I have to go through it all again ;( Thanks for taking the time, Morten
