I have a Dimension XPS 733b with an existing 20 GB HD and I want to add a 80 GB HD as the slave off the same IDE ribbon. The OS is Win98 SE.

After physical installation and bootup, I started up FDISK in a DOS window. I was able to see both HD's, but the new one only had a 10 GB primary partition. Deleting that partion and recreating either a Primary DOS or Extended DOS partition also created only a 10 GB partition. I looked up an article in MSFT's Knowledge Base that indicates Win 98/98 SE's FDISK has a problem with HD's in excess of 64 GB. In particular they will report partition size of only X-64 for disks of size X (X being above 64). Thus with a 74 GB HD, FDISK would report only a disk of size 74-64 = 10 GB. MSFT has an update to FDISK which I have downloaded and will attempt to use tonight. Thing is, this disk is 80 GB, not 74. I'm wondering if the FDISK bug is my only problem. I guess I could always split the HD into two 40 GB drives, but I'd like to avoid that. Anyone seen this problem before?
