After running long or short test, which section should I look and see to tell me if my drive is healthy or becoming bad?

 

What other test should I do?

 

This is what my parity look like:

SMART Attributes Data Structure revision number: 10

Syslog attached:

 

Found some interesting answers from google and this forum - I would like to share some info that comfort me a bit.

 

1)Raw_Read_Error_Rate with RAW_VALUE is HIGH is normal for Seagate drives.

2)WeeboTech writes:

If you start to see Reallocated_Sector_Ct increasing  and/or you see numbers holding or growing in Current_Pending_Sector, Offline_Uncorrectable

then the drive will begin to show issues.

 

I hope this info would help some newbies - comments and other info are welcome.

 

Cheers,

This was Cut & paste from other forum from guy name: bigrigdriver

 

The RAW_VALUE numbers have little to do with actual errors that have occured. It is a six-bit number (with more info) that the VALUE (normalized number). The numbers to worry about are VALUE and THRESH. When VALUE gets close to THRESH, the drive is about to fail. I found this, which might ease your mind:

 

Each Attribute has a six-byte raw value (RAW_VALUE) and a one-byte normalized value (VALUE). In this case, the raw value stores three temperatures: the disk's temperature in Celsius (29), plus its lifetime minimum (23) and maximum (33) values. The format of the raw data is vendor-specific and not specified by any standard. To track disk reliability, the disk's firmware converts the raw value to a normalized value ranging from 1 to 253. If this normalized value is less than or equal to the threshold (THRESH), the Attribute is said to have failed, as indicated in the WHEN_FAILED column. The column is empty because none of these Attributes has failed. The lowest (WORST) normalized value also is shown; it is the smallest value attained since SMART was enabled on the disk. The TYPE of the Attribute indicates if Attribute failure means the device has reached the end of its design life (Old_age) or it's an impending disk failure (Pre-fail). For example, disk spin-up time (ID #3) is a prefailure Attribute. If this (or any other prefail Attribute) fails, disk failure is predicted in less than 24 hours.

 

The names/meanings of Attributes and the interpretation of their raw values is not specified by any standard. Different manufacturers sometimes use the same Attribute ID for different purposes. For this reason, the interpretation of specific Attributes can be modified using the -v option to smartctl; please see the man page for details. For example, some disks use Attribute 9 to store the power-on time of the disk in minutes; the -v 9,minutes option to smartctl correctly modifies the Attribute's interpretation. If your disk model is in the smartmontools database, these -v options are set automatically.

 

Ignore the part about temperatures. The author was using cpu temp as an example of what smartctrl was reporting. You can see from this that the raw value is not reporting actual number of errors.

Would it be possible to automate a regular query of SMART data and, based on a database (config file) of known HD failure indicators, add a health status indicator to the main unraid page???  I'm just wondering. 

That's a good idea... Maybe Joe L./weebotech and/or other linux guru can give us light if this is doable or not. JoeL. this might be a good addition on your unmenu-awk if possible.
