I just plugged in a disk I had shelved a while back and it's spitting out the following errors:

Code:
Jun 29 17:46:44 freenas smartd[2673]: Device: /dev/ada6, FAILED SMART self-check. BACK UP DATA NOW!
Jun 29 17:46:44 freenas smartd[2673]: Device: /dev/ada6, 65286 Currently unreadable (pending) sectors
Jun 29 17:46:44 freenas smartd[2673]: Device: /dev/ada6, Failed SMART usage Attribute: 5 Reallocated_Sector_Ct.
Jun 29 18:16:45 freenas smartd[2673]: Device: /dev/ada6, FAILED SMART self-check. BACK UP DATA NOW!

Jun 29 18:16:45 freenas smartd[2673]: Device: /dev/ada6, Failed SMART usage Attribute: 5 Reallocated_Sector_Ct.


There's no data on the disk that I need to preserve. I was planning on forming a new vdev with another disk I have and this one with the bad sector. I was hoping I could save this disk some how. I've attached the output from a smartctl command I ran on the disk.

smartctl_ada6

Hi Berkyjay,

Well... you can use the drive as a door stopper. It could also be useful as part of lab for opening it and learning about the mechanical that is inside the hard. You can have fun trying to break or bend one of the plate. You will understand after that why they are called --hard-- drives :)

But as for holding data, there is not much to do with that drive.

SMART is very optimistic, and will tell you that things are just fine when they're already going rapidly down the tube.
When SMART admits things are broken, things are very, very broken. You can believe it.
