Also, for W98, if you create the bootdisk from within windows, you will need to go here to download the newest version of FDISK.EXE then copy it to the bootdisk, allowing it to overwrite the older version. This way you will have support for larger harddrives.
FDISK LIMITATION WITH 64GB DRIVES:
Why does FDISK not recognize my disk (or RAID array) which is larger than 64GB?
There is a bug in Microsoft's FDISK under Windows 95B, 98 and 98SE that can be corrected by downloading a newer version. See Knowledge Base Article Q263044 for more information.
When you use Fdisk.exe to partition a hard disk that is larger than 64 GB (64 gigabytes, or 68,719,476,736 bytes) in size, Fdisk does not report the correct size of the hard disk.
The size that Fdisk reports is the full size of the hard disk minus 64 GB. For example, if the physical drive is 70.3 GB (75,484,122,112 bytes) in size, Fdisk reports the drive as being 6.3 GB (6,764,579,840 bytes) in size.
NOTE: This hotfix is not designed for 48-bit logical block addressing (LBA) hard disks, and it is not supported on hard disks larger than 137 GB. However, even if the drive is physically larger than 137 GB, if you create partitions smaller than 137 GB, this FDISK.EXE version will work correctly. (THE FORMAT COMMAND WILL SHOW THE DRIVE AMOUNT IN DOS TO BE OFF THE MARK, BUT WILL BE CORRECT WHEN YOU GET INTO WINDOWS ITSELF)
Direct English Version download:
This package installs the updated Fdisk.exe to the Windows\Command and Windows\Options\Cabs folders, on a computer running Windows 98 or Windows 98 Second Edition. If you are starting a computer from a Windows 98 Startup Disk in order to partition and format the hard disk, you should copy the updated Fdisk.exe from the Windows\Command folder to the Startup Disk, replacing the original Windows 98 or Windows 98 Second Edition version of Fdisk.exe on the Startup Disk.
You can also get around the 64GB limitation of the Windows9x FDISK utility by specifying the desired partition size as a percentage of the total disk size rather than as an absolute size. Alternatively use a freeware FDISK replacement such as FreeDOS FDISK that supports up to 128GB.
One person wrote in a forum: ... as an update on disks greater than 64gb, the FreeDOS FDISK utility does work. First of all, the operating system must be specified in FDISK.INI for it to recognize FAT32. Secondly, reporting of partition size is somewhat peculiar. For a partition between 64 and 90 GB, I have one listed as 39,184GB under Option #4 (Display Partition Info) and -26,402GB under Option #5 (Change Current Drive). I have a 3rd IDE drive connected to IDE1 which is set up as an extended partition. Its letter is changed while in Windows than it is with the FreeDOS FDISK. Finally, the FDISK only works if it is on a bootable floppy. Trying to run it in a DOS window under WIN98 causes the system to freeze. This is a suitable workaround for the 64gb limit, but does take some experimenting. The IBM utility doesn't allow repartitioning from the same physical drive from which the system boots (although not the same partition). A workaround would be to temporarily install a drive on IDE1 or 2 and boot with it, then partition the RAID setup as drive D and beyond...
