Basically it means your harddrive is shot. Dying/dead, toast, etc. STOP. Turn off the computer and pull the bad drive. Go buy a new drive, reinstall windows. Turn off computer and put the bad drive back in. Try to browse it and see if you can save any data. The less you use it now, the better.
Yeah your drive is a goner broseph. go buy a new one. but remember to back up everything you want to another drive maybe an external or something. if it is in a tower i would recommend getting a 7200 RPM drive or higher. if you want a little better performance and a drive that backs itself up when it writes data get two of the same drive and set them up in a RAID 1 with your MOBO. it rocks. I got two 750Gb drives in RAID 1 in mine and I love it.
Any program that "fixes" bad sectors merely marks them as bad so that data doesn't get wrote to the bad areas on the drive. The problem is you have bad sectors and they will continue to spread. And you will continue to write data to sectors that will die later, and lose more data.
I know money doesn't grow on trees. But you need to find a way to get a new drive. Buy a used one off of craigslist or amazon if you need to.
