If you're not using the updated version of FDISK or FORMAT for Windows 98 or Windows 98 Second Edition, you're faced with a cosmetic bug.
When Windows 98 was released in June 1998, hard disks and other media larger than 64 GB in size were not available until the end of 2000. By the time a 75 GB IDE hard drive was introduced that year, it would only show the available capacity as 7,706 MB when initalised using FDISK and formatted. This is because, FDISK and FORMAT used unsigned 16-bit values to calculate capacities in megabytes. Article KB263044 fixes this issue and you can download the fix that Horun pointed out.
However, if you use the updated utilities, FDISK has a design limitation that it will be unable to create hard disks larger than 512 GB (524,287 MB). Also, because FDISK uses 5-digit figures to store the hard disk capacity, capacities over 97.66 GB (99,999 MB) will have the first digit omitted. To get around the 512 GB limit in FDISK, you will need to use a 3rd party hard disk partitioning utility.
