Re: Sata Hard drive testing

[Thomas Anderson]

Thank you everyone that helped me with this issue.

I learned a great deal.

Namely, for my particular use case, SMR drives are sub-optimal.

It is VERY difficult to even find out if drives are SMR or CMR, because

apparently the manufacturers try to put it all out the door. As mentioned

by Mr. Ritter, the information of writing technology is not disclosed 
easily,


and in some cases, bordering on deceptive.

I will replace this drive since I have little faith in it, as it was 
originally purposed,


important backup. I will just use it as a redundant backup or just a 
short term/temporary


storage drive - and monitor it.

Very Interesting and most informative Dan, and thank you.

Carefully reading between the lines of several hits also explains why I 
stopped having major failures of amanda, the backup software, when I 
replaced a 1Tbyte seagate with a 240 gig series 860 samsung SSD, used as 
a holding disk while amanda is collecting its data to be written to tape 
w/o shoeshining the tape while at the same time cutting the time to do a 
20 gig backup from 3 or 4 hours, to 20 minutes.

This post is also being sent to the amanda-users list to alert the users 
who are currently being affected by this and not finding a definitive 
answer.

Bottom line for amanda users is, do not use todays spinniing rust drives 
as holding disks. They are simply not trustworthy for short term buffer 
storage.

Symptoms are reported to the user as crc errors in the holding disk. That 
particular DiskList Entry is then repeated until a good crc is obtained. 
But that also leaves the bad crc data left on the holding disk 
eventually using up its capacity without manual intervention to clean up 
the mess. A genuine PITA for us, and leaves the drive makers in an 
unfavorable, bad dog, no biscuit light.

Cheers, Gene Heskett.

Wikipedia is quite helpful for such queries.

Searching for 'SMR' brings one to a fairly long disambiguation page, but 
there is only one entry mentioning hard drives ;)

The first two paragraphs of the article is already quite informative on 
why one might want to avoid SMR drives.

You should be able to return this drive without proving that it
is defective; this is one of Seagates' SMR drives that they did
not disclose were SMR.

RAID is meant only for uptime, backup is something else, see: 
http://taobackup.com/.

Mostly agreed with btrfs[1] (though ZFS is probably better, if you are 
fine with out-of-tree kernel modules[2]).

On the other hand mdadm can't detect silent corruption. In case a flaky 
drive (like the one discussed here) returns corrupted data claiming it 
is good mdadm RAID can't detect this, and in case it detects it, it has 
no way to determine which data is good.

Worst case it might even overwrite the good data with the bad one 
(because the bad data appears to be newer).

It's not. You have a Seagate, after all, and those are good only as long
as trash can is considered :)


But anyway, it's not new.

It has bad sectors, a small amount compared to the drive size.

And you had some problems with the drive in the past, which could be a
bad SATA cable, but could be the drive itself:

Assuming you make backups, I'd call this drive servicable. I'd replace
it sooner or later, because it has bad sectors, but it won't be the
first priority.

I have similar Seagate drives (4), and they look like this:

Device ModelST2000DM006-2DM164
9   Power_On_Hours  20124,20125,23527,23511

183 Runtime_Bad_Block   2,3,1,1 yours 5
187 Reported_Uncorrect  0,0,0,0 yours 1334
195 Hardware_ECC_Recovered my HDDs don't have that field, yours 7226480
197 Current_Pending_Sector  0,0,0,0 yours 5
198 Offline_Uncorrectable   0,0,0,0 yours 5

Clearly you have problem with surface errors. 1334 reported bad sectors,
5 current pending sectors and so on. However, last full surface read
test SMART "long" test you performed at 14551 hrs (7 hours before
fetching this SMART data) has passed, meaning drive is still able to
read all sectors. That means it still has spares and/or it doesn't have
any more unknown bad sectors.

Another good news is, that SMART log has logged last error in 10525
power-on hours. You are on 14558 hrs. That's 4033 hrs or 168 days ago if
you run it 24/7. That means, drive is not discovering new bad sectors,
either because you don't read or write to certain surface spots where
undiscovered bad sectors are, or simply because remainder of the drive
is in good condition.

If your drive is still on warranty, you should return it, most likely it
will be accepted based solely on smartctl results. If not, you can do
following:

Change data cable first thing, as also Gene suggested

Watch these five metrics very closely:
183 Runtime_Bad_Block   5
187 Reported_Uncorrect  1334
195 Hardware_ECC_Recovered  7226480
197 Current_Pending_Sector  8
198 Offline_Uncorrectable   8

If any of these raise rapidly over time (maybe except ECC errors, which
are usually kinda normal nowadays), you may consider retiring it.

Also do smart "long" test every 1 month or so. Check SMART results after
each test.

Lastly, you should use it in RAID1 or similar mode, to ensure there is
always backup of data this drive keeps. You can try Btrfs raid1 or mdadm
raid1. Whatever you choose, try not to use this drive without any
backup, as you are not sure yet if damage are not progressing.

Here are the results, of my smartctl test:

I am trying to parse them myself, to see if I can learn anything. But,
immediate glance

and queries did not reveal anything that could help me determine if the
drive is good or not.

"it says"?  Can you clarify what is this "it"?

Drive-level errors of "unreadable data" normally lead to errors that
appear in the kernel log and say scary things and "read sense" and
include hex numbers showing the actual bytes of the SATA command sent.

I don't expect such error messages to say anything about a "trash".
So maybe your errors occur elsewhere.

Is there any kind of test I can execute on this drive to show it needs 
to be replaced??


Thanks!



The canonical testing tool is the one made by the drive manufacturer. 
This is the definitive way to obtain a warranty RMA.  For example, Seagate:


https://www.seagate.com/support/downloads/seatools/


As suggested by other readers, smartctl(8) can be used to obtain 
information from the drive controller, direct the controller to perform 
short and/or long self-tests, etc..  If your drive is out of warranty, 
you want a second opinion, you want to do periodic monitoring/ logging, 
etc., this tool works well.



But before you blame the drive, you also have to eliminate the SATA 
interface (typically on the motherboard), the SATA cable, the power 
supply, and all connections.  This means you need at least two 
interfaces, two cables, and two drives; it is best to have a second 
computer with two interfaces to confirm.  Test all of the permutations, 
work up a truth table of results, and find the bad component(s) by a 
process of elimination.  Beware that you may have more than one bad 
component, and that the failures may be intermittent.

Re: Sata Hard drive testing

Have a look at "smartctl". It will print some info about the drive and
can also "test" your drive known as S.M.A.R.T-test.

First of all i would have a look what "smartctl -a /dev/sdX" will say.

Cool, thanks Reco!

Assuming it's SATA/IDE drive, all you need to do is:

apt install smartmontools
smartctl -t long 
# wait for the test to finish
smartctl -a 

Please post the output of the last command.

Sata Hard drive testing

[Thomas Anderson]

Hello Gurus,

I have been having problems with a drive (non-SSD) for a while now, but 
I would like to "identify" the problem specifically, so that I may 
perhaps be able to get the drive replaced.


Essentially, I have been experienced data loss, where nodes become 
unreadable, when I try to "fix it" with fdisk, it says it moves 
unreadable to the trash, basically deleting data.


I have tried reformatting the drive, writing zeros to it, and then 
temporarily the drive looks fine; but it's not! it's as if the drive is 
some how decaying: where it looks good, but then when you go to use it, 
the data later becomes unreadable.


Is there any kind of test I can execute on this drive to show it needs 
to be replaced??


Thanks!
