I have a 6.4Gb IBM hard disk which I have formatted several times during its 5 year life. I reformatted it again but this time it reported a strange size 6200.48Mb. Now when I try to run FDISK I get the following error message " Error reading fixed disk."

I'm running Windows 98Se and used the versions of FORMAT and FDISK that come with thet version.

When it auto-detects in the BIOS it shows the correct size.

What can I do?
