does i/o error mean "trash this drive"?

[camner]

I have a (somewhat old) 1TB seagate drive that is throwing i/o errors on reading a particular file. Fortunately, I have a backup, so I'm not worried about loss of data.

Once this has happened, can I conclude that the drive is now unreliable and should be discarded? Or is there a process I can go through that might map out the bad sector(s)?

The drive is likely to still be good, but with a few bad sectors. I have a drive that has a few bad sectors all together and I can't read the one file because of it. The drive has been like that for a few years now. I've just hidden the file and moved it to the root of the drive. No problems until I have to format the drive and then I wait for a new bad file to take its place.
