I think my HDD is fried... Could someone confirm or help me restore it?

I was using Hardware RAID 1 Configuration [2 x 160GB SATA HDD] on a CentOS 4 Installation. All of a sudden I started seeing bad sectors on the second HDD which stopped being mirrored. I have removed the RAID array and have tested with SMART which showed the following error:

187 Unknown_Attribute       0x003a   001   001   051    Old_age   Always   FAILING_NOW 4645

I have no clue what this means, or if I can recover from it. Could someone give me some ideas on how to fix this, or what HDD to get to replace this?

  • How did you see bad sectors if it was being hardware RAIDed?
    – Chopper3

  • When the Drive failed, the HardWare Raid became transparent and I could see /dev/sda/ and /dev/sdb/. Funny thing is it showed /dev/sdb as the active HDD. I then decided to check with a Live Linux Distro, and ran the SMART scan along with e2fsck. I then found that my /dev/sda was healthy but my /dev/sdb had errors, proceeded to format and remove RAID setup from BIOS, and then once again run the SMART tool analysis I posted above.

  • Thank you. I dreaded this answer but I had a feeling this was the case. Looking for a replacement right now.

  • @Hubert Kario A little more explanation why this disk should be considered dead would be helpful. Which column values to compare for instance...

    @ProBackup: for those two SMART values you want to look at RAW_VALUE, if it is non-zero, it means the drive is failing. Any value over 10 means the drive is long dead. Current_Pending_Sector sometimes can be "fixed" by performing read and write on the failing sector (LBA_of_first_error can be helpful in this regard). Dec 29, 2012 at 13:57
