Recently my hard drive on my desktop CPU has been screwing up lately. As of thirty minutes ago, it now tells me that I must run another disk check for the third time in a week because there are corrupt files. But when I run disk check, it says there's problems and I have to use system restore to get to a previous point so it can run it. But then I can't run system restore because my HDD has too many bad sectors and must be fixed before using any restore points. 
I've had it with this thing and I want to just wipe, reformat, and reinstall windows. Tried to use Western Digital's software to wipe it clean but it tells me that I can't wipe my Windows drive.
What can I do??? Thanks.
