Hi, I'm trying to extend my C drive with partition magic, however, when I try to apply it says the drive has lost clusters and too many errors. I've run chkdsk /r and at first it said the vol was clean, now it says the vol is dirty, and PM still won't let me do it cause of lost clusters. The lost clusters seem to be at the end of the C drive. I'm running diagnostic on the Hd with hirens boot disk-can anyone help please? Thanks
