A couple of days ago, someone brought a computer to me to take a look at. They told me it was slow and they asked if I could fix it. Anyhow, I turned it on. It booted Ubuntu 10.10, got to the desktop and the screen went blank, then the desktop reappeared. Then every time I moved the cursor, it would do the same thing. Since I figured the OS was damaged, I was going to just install Windows 2000 on it. I then shut it down, hit the power button, went to the CMOS screen so it would pause booting and I put the CD in. I noticed in the Basic CMOS menu that the C: drive just said HARDDISK, not the brand or model or anything. I went ahead and booted from the CD and started formating the hard drive. It was EXTREMELY slow for just a 60 GB. 2 hours in, I was at 17%. I could not stay up all night with it so i canceled and shut it down. The next day, I went to retry. It would not format at all. I tried using a Win 98 boot disk with some utils on it, using FORMAT, FDISK, and SCANDISK. FORMAT kept saying that C: was not a valid drive specification and so did SCANDISK. FDISK told me that the hard drive may be damaged. I also distinctly remember something telling me something about head 0 could not be read.
