I ran a smart history this morning and I am not sure which numbers are serious problems. Can someone please take a look and let me know what should be replaced?

 

I think I have read that the Raw_Read_Error_Rate  is normal to have a high value or points to a cable issue rather than drive itself.

 

Thanks for the help

(a)  Are you having problems with the array?  i.e. any read errors shown on UnRAID's Web GUI and/or disabled disks?

 

(b)  Are the drives showing the errors all Seagate drives?

 

If the answers are No and Yes, then everything's fine.  Seagate reports the raw errors; WD does not.  I don't see anything to worry about.

 

I believe they are all seagate. Two show up as Hitachi but I have never bought a Hitachi drive. If memory serves they are Seagate.

 

I am not having any problems was just looking and trying to avoid them.

 

So errors like this are nothing to worry about?

 

Disk 4: *ERROR* - Reallocated_Sector_Ct it is now 33 (error threshold is 30)

 

 

Disk 4: *ERROR* - Reallocated_Event_Count it is now 55 (error threshold is 30)

 

Disk 4: WARNING - Power_On_Hours it is now 20427 (warning threshold is 20000)

 

Thanks again, just trying to avoid data loss.

I would be worried, but only if the reallocated sectors is ramping up. If that drive has had those 33 sectors for many months with no increase, then I'd feel a little better. If the 33 just showed up in the last month or so, I'd replace the drive. The raw numbers aren't as meaningful without a rate of increase included.
