Re: [opensuse] Interpretation please
Hello,

On Mon, 01 Sep 2014, Basil Chupin wrote:
I just ran smartctl on my 2 drives, sda and sdb, with the following
results. Could someone please interpret these results and tell me if
there is cause for worry.

As these are Seagates ...

*sda*

1 Raw_Read_Error_Rate 0x000f 117 099 006 Pre-fail
Always - 130073028

This seems to be normal for those drives.

3 Spin_Up_Time 0x0003 100 100 000 Pre-fail
Always - 0

That's bogus. *No* rotating rust drive spins up in 0ms ;) But I got
the same on the 3T newer Seagate ST31500341AS (the only one not external).

4 Start_Stop_Count 0x0032 100 100 020 Old_age
Always - 1006

ok

5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail
Always - 0

very good

7 Seek_Error_Rate 0x000f 076 060 030 Pre-fail
Always - 4341556312

still "typical" for these drives, I think.

9 Power_On_Hours 0x0032 087 087 000 Old_age
Always - 12166

definitely ran a bit ;)

10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail
Always - 0

this is good.

12 Power_Cycle_Count 0x0032 100 100 020 Old_age
Always - 933
183 Runtime_Bad_Block 0x0032 100 100 000 Old_age
Always - 0
184 End-to-End_Error 0x0032 100 100 099 Old_age
Always - 0
187 Reported_Uncorrect 0x0032 100 100 000 Old_age
Always - 0

all good

188 Command_Timeout 0x0032 100 094 000 Old_age
Always - 3228

not very good, but can't compare (my smartd/smartctl on that box is
too old for that disk)

189 High_Fly_Writes 0x003a 100 100 000 Old_age
Always - 0
190 Airflow_Temperature_Cel 0x0022 072 053 045 Old_age
Always - 28 (Min/Max 17/29)
194 Temperature_Celsius 0x0022 028 047 000 Old_age
Always - 28 (0 10 0 0 0)

ok.

195 Hardware_ECC_Recovered 0x001a 042 027 000 Old_age
Always - 130073028

That's normal, I think, for those disks.

197 Current_Pending_Sector 0x0012 100 100 000 Old_age
Always - 0
198 Offline_Uncorrectable 0x0010 100 100 000 Old_age
Offline - 0

very good.

199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age
Always - 1

This would point to a flaky cable/connection, if it were higher.

240 Head_Flying_Hours 0x0000 100 253 000 Old_age
Offline - 5553392728641

Typically bogus / smartctl not recent enough. Nothing to worry about
though.

241 Total_LBAs_Written 0x0000 100 253 000 Old_age
Offline - 2804485771
242 Total_LBAs_Read 0x0000 100 253 000 Old_age
Offline - 33088652

Uh? That much more written that read?

7 Seek_Error_Rate 0x000f 067 060 030 Pre-fail
Always - 17202052028

That's a bit high... Compare to the other disk (and each "Power_on_Hours")

9 Power_On_Hours 0x0032 088 088 000 Old_age
Always - 11380
[..]
Thanks in advance.

BTW, both drives are Seagate Barracuda 1TB SATA 3 and are 2 years old.

sdb might have a mechanical/mounting problem, manifested in those high
seek errors... It might be as easy to fix as to loosen the screws,
realign the disk horizontally/vertically, and retighten the screws ;)
Have an eye on that value, but don't mind yet.

But: I've had one newer 3T Seagate (not of Samsung descent, I think)
those disks recently, with similar SMART-values jump from such as
above to >12k bad sectors (realloced / pending / uncorrectable)
overnight. Several 1.5T disks (same age as yours) developed just a
few sectors (e.g. 6), nothing dramatic, most Windows users will never
notice stuff like that ;) I've had a Laptop to switch out the drive,
and it had >1k realloced sectors and the user never noticed (but
probably some files may be damaged, but migration went fine, so it
hopefully just were some system-files ...
