I have a spare AOpen Mobo MX 46-533V. So I decided to put in an older second hand (ebay) 20Gb hard drive and memory. 6 months ago - memory, mobo, cdr etc were all working fine. I built a new super system leaving me with these parts. Anyway, i decided to build a second system and installed the 20Gb hard disk but couldn't load windows, I got loads of error messages resulting in one messages saying hard drive could be damaged. Rubbish seconds I thought. So I bought a brand NEW 40GB Maxtor and this is doing the same. At first it loaded windows up to the point where the blue bar scrolls accross the bottom and then it freezes. I tried to delete the partition and then reformat and re install windows. Now all I get is bad partition message, disc may be damaged etc. This can't happen on 2 discs, can a faulty installation somehow damage the hard disk beyond repair? Any ideas?
