I have had several number of problems with bad blocks on drives in the past year or two after many, many years of no problems. One of them continued to get worse and one never changed after getting a batch of bad blocks. However, it doesn't means that the drive is completely toast. Once I start getting the bad blocks I used badblocks once a week or so (assuming that the drive is usable at all) to see if it is getting worse. This will also tell you what percentage of the disk is bad, which may help determine if you want to scrap the drive or not. I start by mapping the bad blocks out to prevent future problems. You will lose the data that was stored in the bad block, but you will retain the rest of the disk. You can also use tools like dd_rescue to make an image of the disk with the bad blocks replaced with whatever it supplies on errors, probably zero bytes.

The error is saying it encountered a bad sector and can't read the drive. Of course, there's always a slim chance that it's a bad data cable or connection, but you should assume that the drive is now dead. If you don't have current backups of everything on that drive, good luck.
