Is my disk dying?

Hello everyone,
here is my smartctl output for my main disk, a 500 GB Seagate Momentus 7200.4 mounted on a Dell XPS L702X:

Is, in your opinion, my disk dying? I am concerned by the pretty high Raw_Read_Error_Rate and Seek_Error_Rate.
Also, I'm asking this because I'm experiencing a *LOT* of segfaults, core dumps and all sort of crashes and system hard freezes, apparently without a precise reason. Here is my other (hopeless) forum request about those problems: link.
I would like to understand if my problems may be related to an imminent disk failure and/or a SATA link failure.
Thanks.

Re: Is my disk dying?

It doesn't look like you've even run any tests; that's just information on the disk's SMART capabilities.

Re: Is my disk dying?

He did around 10k hours, but the current hours are nearly double that.  Run a short then long test again.

Re: Is my disk dying?

The disk itself seems to be ok. High raw values for some of the parameters seem to be "normal" for some disks, you should look at the normalized value and threshold. The disk has no logged errors, no pending sectors and no reallocated sectors, if you are seeing problems they might be caused by something else (sata link problem, ram problem, cpu overheating .....).

Re: Is my disk dying?

Thanks for the replies, I'm doing right now a short test, then I'll do the long one. Actually, I did the complete SMART test suite something like a month ago, and it did not report anything wrong with the disk.
I'm going to report test results here, later today (if I can find it in the mess I call home) I'll try another disk to see if I can exclude a disk failure, or this problem is related to SATA link as you are suggesting.
Thanks again.

Re: Is my disk dying?

I had the exact same thinking today. It seemed like my disk had died due to all kinds of errors. I first thought it was due to a btrfs partition, but after rebooting it also happened to another disk. Windows, on the same disk, still booted alright. So I tried the LTS kernel and it booted without problems.
I immediately went here and there your post was at the top of the forums.

A few things that might be related here: I'm using the linux-ck kernel and, like I mentioned earlier, using btrfs for one of the mounts. Root is still ext4 though.

journalctl says I had a lot of errors like the following:

kernel: ata3.00: status: { DRDY }

I actually had some ata errors (like your "DRDY", reported above) in my logs, together with all sort of random segmentation fault errors, but since I need a stable environment for my thesis work at university, I just tried with a clean Arch installation, and ata errors just disappeared from dmesg and other logs. Now, after some weeks, even in this clean new install system freezes, random programs crash and all sort of nasty things reappeared and I just don't know what exactly the problem may be. This is not good for my self-esteem, too.
I'm sorry I can not help you more than this rumbling.

Re: Is my disk dying?

Hmm, not sure our problems are that similar then. If it did indeed happen before, I'd suggest you test the disk thoroughly from the live CD/USB.

I'm not sure neither, I'm quite confused about this problem. I already tested disk with an offline fsck (in a Live CD) and I even tried Seagate proprietary test suite, without any error being reported.
For what matters RAM, I also completed several memtests, without any error being reported as well. Right now, I'm completing another extended SMART test on the disk, and when I manage to, I will try a clean install on another spare disk I have for a few days, trying to exclude disk/SATA link problems.

Selective self-test flags (0x0):
  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

What degree of certainty gives me this? What should I try next in my attempt to exclude SATA link and disk failure problems?
Thanks for the insights.

Re: Is my disk dying?

If you want to make sense of the raw read error rate etc., see here: http://www.users.on.net/~fzabkar/HDD/Se … R_HEC.html

In my opinion the disk looks grand, apart from the free fall bit (but that's just a statistic)

Thank you very much for the material, I just wondered how I should read those metrics.
Have a good day!
