You should change the drive and start over.
If you must try to salvage the drive then your first step would be to have all files you can't lose on your backups.
The second step is to boot up something like GPARTED (see google) to delete all partitions on said drive then install again. This will give it a clean start.
Hi. I am having trouble getting the computer to fix the errors I have on a hard drive. I formatted it on a Win7 machine a few months ago, backed up some information, and would like to use it now. The problem is that I have an XP computer. Somehow, it can't recognize the disk, so my assumption is that a computer can only read disks if they are formatted with their OS or later (i.e. a Win8 computer could read the HDD I Think). My solution is using VMware workstation with Win7. With this I am able to correct the errors after plug-in as it prompts me to check for errors, as the disk is "dirty". I ran that, and it finished, but then I forgot to dismount the disk and I pulled it out. I have then tried again to fix errors, but it fails. Here's a link to a picture of what I got in CMD after running CHKDSK F:\ /R
