I've got some errors on a hard drive.
The server is running CentOS 4.5 with SATA drives.
These are the errors in /var/log/messages:

Dec  1 10:41:02 twins smartd[2580]: Device: /dev/sda, 11 Currently unreadable (pending) sectors
Dec  1 10:41:02 twins smartd[2580]: Device: /dev/sda, 11 Offline uncorrectable sectors
Dec  1 11:11:02 twins smartd[2580]: Device: /dev/sda, 11 Currently unreadable (pending) sectors
Dec  1 11:11:02 twins smartd[2580]: Device: /dev/sda, 11 Offline uncorrectable sectors

The server seems to be running fine right now.
I don't want to lose any data.
Is there anything that can be run to attempt to fix this problem, or is replacing the drive the only solution?

Thanks

The drive is toast. Get all your data of it and replace it yesterday.

smart errors cannot be fixed, they are a "log" of the disk operations, and are updated continouosly.
I have a couple of disks with smart errors, that keep running fine for months, and a disk test shows no platter problems.
That said - i would not keep them for secure operations, but as temporary backup , or spare parts ...
It is a shame you cannot even reset the smart options, for testing

I concur with Nobus  on this head as I have kept drives with bad sectors and smart errors for use as extra backups. I would not use one in a boot drive or in a server array so I still say replace the server drive with new but nobus is right, the drive can still serve at home as a spare.

I couldn't even get the server to reboot so the drive was replaced immediately.
