When I format the HD (20G-ntfs) I get about 90% complete when I get a message that the HD may be corrupt. (I did this three times) I have installed the disc on a Win 98 pc and was able to format it and run a thorough scan disc with out any errors. I then put the disc back in the original pc and tried to format it again and got the error again. I tried to format it to a FAT partition and also received the errors. So for grins I decided to format a 10G partition and was able to install XP. I then went to disc manager and created another 10G partition on the remaining drive space. I was able to format and run a scandisk on the second partition without any errors. Any idea why I can?t format the whole drive but if I create two drives I have no problems? Is there any MS articles on this? Thanks in advance for any help with this.
