I got the following output from the smartctl -l errors /dev/hda

It could signal something bad is about to happen, but it is still operational. If you value your data, backup regularly, and if you wouldn't like surprises I advise you to RAID 1 your harddrive with another drive.

And although RAIDing is a good idea anyway, can you post your attributes?

Code:

smartctl -A /dev/hda

here are mine:

You should keep an eye on Raw_Read_Error_Rate and Reallocated_Sector_Ct, those tell you about a physical platter problem.
There are attributes specific to vendors and models, but I think that 1-99 is a shared standard.

Code:

I left all the reasons-to-be-worried.
First the the Raw_Read_Error_Rate which is high. Reallocated_Sector_Ct said you have 80 bad sectors which was automatically relocated by the drive.

I'd say replace this drive, or for the very least have another drive in RAID1 with it.
