Welcome to the PC Guide Discussion Forums Broadsword
It seems as though you have the cable and jumpers set correctly? If the HD is indeed using NTFS Windows 98 won't recognize it. When you tried fdisk did you use a boot floppy? Can switch to the drive in pure DOS? You will have to delete/remove the partition table on that HD before you can enable FAT32. Unless you want the data on the HD I wouldn't bother with converting from NTFS to FAT32. Be careful when using fdisk...make sure you are where you want to be.
Post back if this is no help so the other folks can offer some better advice
