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 ... -dnh --
