Also today, when I was booting Linux it was not booting. So I have restarted the boot and it worked without problem. This was before this error popped up. No idea if this boot issue has something to do with the smartmontools error. The booting issue was before I had this error warning.

Confusing: In the reoprt there is a line "Error 1 [0] occurred at disk power-on lifetime: 8134 hours (338 days + 22 hours)". But there is no date. My expectation was, that there would be a date at which this error occured, so that I can show what todays date is and can definitely assign the error to the date of today. As I did not found a date in the whole output of the txt file, I was looking for the actual lifetime of my sshd, because it was said, that the error occurred at 8134h. So my expectation was, that I can somewhere find the amount of hours my sshd has run until the current time. But I also did not found this.

Which host's syslog is meant? Maybe this one: /var/log/syslog ?

If yes: Here it is: https://workupload.com/file/NVD2gpdrvHp

But my main question is: Is there a high risk, that my sshd soon will die?

It is said, that the hard disk health status has changed. But where can I now find the current health status?

Thank you.

  • Your topic asks whether you should replace you sshd? The answer to that is probably no, but it's completely unrelated to anything in the actual question. Oct 24, 2022 at 9:17

    @Henriksupportsthecommunity In this context, SSHD would mean a hybrid disk, or in other words, a HDD assisted by an integrated SSD component. That's just how Seagate has chosen to name them.

Offline Uncorrectable Sectors

From the image you have posted, and also in text, there is already 16 unreadable/unwritable sectors.

As a past worker in data recovery, I recommend using ddrescue (man page) to copy the healthy remaining parts of your disk to some external medium ASAP.

Passing SMART is irrelevant as well as POHs at this point.

Now, that you have used ddrescue and can confirm there is an actual problem, completely another question would have been to find out which files are affected, which you cannot find from ddrescue's logfile.

You need to successfuly mount the ddrescue image, as root:

mount -o ro,loop,offset=$(( sector size, usually 512 * an actual offset )) /path/to/ddrescue/image /mnt/point/

Find errors = files affected:

cp -PRv /mnt/point/ /path/to/extracted/files/ 2>>/path/to/extracted/files/ERRORS.txt

These are just examples. Always double check paths and do not copy-paste.

    @Wogehu You can never find files affected until you do a ddrescue image, mount it and copy all files from it elsewhere with errors logged, which would be for another question. Oct 25, 2022 at 4:56

    @Wogehu I did not mean log file, which serves only for ddrescue's purposes. I will edit my answer to make things clearer for you. Oct 25, 2022 at 6:58

The drive itself does not know any date, nor is there a way to set one. It simply counts its own power on hours, and even that counter may be a rough one and not count correctly, if the drive only ever runs a few minutes at a time.

Your current Power On Hours is 11853 so maybe you can deduce the date based on average time this system is running per day. Or maybe you are logging the Power On Hours value somewhere else, so you could deduce a more exact date that way.

Your drive has unreadable (pending, uncorrectable) sectors so it's possible you already lost some data. Do you have any backups to compare with, or checksums you could check?

Personally I would replace it first (use ddrescue to handle read errors) and then test it more thoroughly. Error counters reported by SMART are always minimum values, i.e. problems the drive encountered without deliberately looking for them.

So there could still be many more errors currently not being reported.

In the future, also consider running long self-tests (or selective self-tests) as the short test may not be enough to detect read errors reliably.

  • Can be seen in GSmartContol Output, if the SSD part of the SSHD or the HD part is affected?

    @Wogehu should be the HDD Oct 23, 2022 at 17:09

I would be worried in particular about this:

  7 Seek_Error_Rate         POSR-K   082   060   030    -    4473742513

You have a significant seek error rate (which has been worse in the past).

One uncorrectable error for a block can happen, and is nothing to worry about by itself, and even the 16 pending ones can happen, but based on the seek error rate, I wouldn't trust this drive, and when these drives fail, they usually fail quickly, to a significant degree, and surprisingly.

Run a badblock scan, run a long self-test, and decide what to do based on the outcome. This disk may be fine for system files (or anything else you can recover easily), but I probably wouldn't put important data on it.

Which host's syslog is meant? /var/log/syslog?

Yes. It will likely show the same error that's in the internal log, an uncorrectable READ DMA EXT at LBA 0x00a03a40.

I was looking for the actual lifetime of my sshd

  9 Power_On_Hours          -O--CK   087   087   000    -    11853

SMART values are normalized to 100 (lower is worse), and when they go below the indicated threshold, the drive is considered "failing". That's why your drive still passes: All values are above the threshold.

It is still working, it has a few bad blocks (which can happen), and it's possible that once you reallocate those blocks it will be fine for quite some time. So you can still use it, but as I wrote, when it fails, it will probably fail suddenly, as the high seek error rate already indicates some problem (probably mechanical).

  • I think, I will replace this SSHD as soon as possible. But why is the "SMART overall-health self-assessment test result" nevertheless "PASSED". I always meant, that this means the SSHD health is well. (?)

    The "passed" or "failed" is a decision the firmware makes, you'd have to ask the manufacturer to get exact information how a specific drive decides that (and you're unlikely to get an answer). It might have to do with the fact that the drive probably never executed a self-test, so the self-test status is still good. Oct 24, 2022 at 10:48

Probably, but run a proper test first.

Specifically, you want a long self test of the disk. As root from a terminal smartctl -t long /dev/sda (assuming the drive is /dev/sda, and then come back in roughly an hour and forty minutes and check the output of GSmartControl again.

This will force the disk firmware to run it0s own internal test suite, and should result in some changes in the output of GSmartControl. In particular, you are looking for any of:

  • The ‘SMART overall-health self-assessment test result’ changing to something other than PASSED.
  • An increase in the raw values of any of attributes 5, 196, 197, or 198.
  • One or more additional errors in the ‘SMART Extended Comprehensive Error Log’ section of the output.
  • A new entry in the ‘SMART Extended Self-test Log’ section showing something other than a - in the LBA_of_first_error column.

If you see any of those things after running the extended self test, you should look at replacing the drive immediately.

If you see none of those things after running the extended self test, still consider replacing the drive, but it’s probably not as urgent. Definitely keep monitoring it though.

But what about that logged error?

The drive has spent 11853 hours powered on (raw value of attribute 9, also possible to infer this from the the ‘SMART Extended Self-test Log’), so this error happened long ago and can probably be safely ignored.

As a quick bit of background, this stuff is not listed with dates because there is no way for the system to map these numbers to exact dates. The drive has no internal clock, so it can’t record dates itself, and the system itself has no idea how much time the drive has spent powered off (which would be required to map the time spent powered on to a specific date and time).

What about the Offline Uncorrectable Sectors / Current Pending Sectors?

These metrics actually highlight one of the big issues with SMART. Because you only get a point-in-time snapshot of the current values with no historical data, and there are no timestamps for when the last change in the counter happened, there is no way to differentiate between events that happened in the distant past and those that happened recently, or between sudden changes and steady increases.

These particular metrics are one where this differentiation actually matters. If you get a sudden unexpected jump in either of these numbers (or the count of reallocated sectors), or they are increasing steadily, then those situations are concerning. If you get only one or two over the course of hundreds of hours, and it mostly just stays the same, then it’s not really as much of an issue (still something to watch, but it’s not going to eat your babies).

For your particular case you’re probably fine (you’re nowhere near what typical drives have available as backup sectors for reallocation) unless the number keeps changing or jumps up again suddenly.

Then why do you suggest replacement if everything is probably fine?

However, there are other things that are potentially concerning here. The biggest issue I see is the particularly high seek error rate (attribute 7). This is almost never zero, but it’s unusual for it to be high enough that the normalized attribute value dips below about 90. In most cases, this is indicative of mechanical issues inside the drive itself, which in turn is a pretty reliable indicator of impending failure. You also have a non-zero number of high-fly writes (also generally indicative of mechanical issues).

Given this, I would seriously consider at least starting to plan out replacement of this drive (with an SSD if possible, they solve most of the issues with using traditional hard drives in a laptop, and should both speed things up and give you a slight boost to battery life). You absolutely want to replace it before it fails though, mechanical failures of hard drives are almost always sudden and catastrophic, and it’s often not possible to actually recover any data afterwards.

  • This was very helpful. After the long self test I have now 20 new errors and an entry in the "LBA_of_first_error" column.
