Thank you for posting your data, here is my reading of smartctl data:

> 
> === START OF READ SMART DATA SECTION ===
> SMART overall-health self-assessment test result: PASSED
>

this you can ignore, I have held in my hands disks that reported "PASSED"
but were dead, could not read, could not write anything. Also had
disks that worked perfectly but reported "FAILED" here.


Next goes the meat of the data:

> ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE UPDATED  WHEN_FAILED RAW_VALUE
>   4 Start_Stop_Count        0x0032   100   100   000    Old_age Always       -       26

Your disk is brand new, only ever saw 26 power cycles.

>   9 Power_On_Hours          0x0032   051   051   000    Old_age Always       -       19725

Your disk is brand new, 19725 hours is 2.2 years.

> 194 Temperature_Celsius     0x0022   100   100   000    Old_age Always       -       32 (Min/Max 20/37)

You have good cooling, temperature is 32C, as high as 40C is usually okey, above 50C means the cooling fans are dead.

>   5 Reallocated_Sector_Ct   0x0033   100   100   050    Pre-fail Always       -       0
> 196 Reallocated_Event_Count 0x0032   100   100   000    Old_age  Always       -       0
> 198 Offline_Uncorrectable   0x0030   100   100   000    Old_age  Offline      -       0
> 199 UDMA_CRC_Error_Count    0x0032   200   200   000    Old_age  Always       -       0

Your disk does not report any problems reading or writing data to the magnetic media.

Conclusion: healthy as a bull.
