johnm160 Posted February 10, 2014 Share Posted February 10, 2014 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 SMART_unRAID_Server.txt Link to comment
garycase Posted February 10, 2014 Share Posted February 10, 2014 (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.

johnm160 Posted February 10, 2014 Author Share Posted February 10, 2014 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.

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. Link to comment
