Failing HD, checkdisk and diagnostic tools

Hello everyone. My 320 GB external hard drive had a problem before where checkdisk would get stuck at a certain percentage in Step 5.

I've since backed up the drive and then reformatted it. I did a quick reformat (should I do a long reformat?) and then ran the hard drive with checkdisk overnight. I have about .02% in bad sectors. Is that a bad thing? Can I still use the drive as an external drive safely or do I use this drive at my own risk? Also, should run any other HDD diagnostic tools?


Here is the summary of the checkdisk findings.

I would run the manufacturer's disk utility and do a diagnoses on the drive. Also with the utility do a low level format which might retrieve some of the disk space since windows marks it a bad sector if it takes to long to read the area.

So I went to the manufacturer site and ran their program and it said that it there were too many bad sectors detected. I guess that means its pretty much done right?

unfortunately no. I'll probably just trash it unless there are other uses for a HD full of bad sectors...

thanks for your replies
