Something very funny has happened to my hard drive of late - a part of the hard drive seems to have been damaged and I'm not sure how it happened or how to fix it. There are bad clusters everywhere, most of which Scandisk has claimed to have fixed yet I can't install Windows or ANYTHING on the HD. I've done a hard format and a full 7-pass wipe TWICE and still the problem continues. After a fresh wipe I've made partitions and most of them sit there for an hour with the message 'finding allocation cluster' or something along that line. In a surface scan I spot a bunch of bad cluster markings but full formats just won't cure the problem. Can anyone here help out with this problem? I'm completely stuck with it and don't know the way out of this one. Thanks in advance.
