Hi,
It appears that ht previous owner used either Unix or NT. This is easy enough to fix. I suggest a program called partition resizer. It has a few more features than fdisk and heck, it's freeware and works from a dos prompt. Also, if you remove the help file from a 98 boot disk, it should fit on it as well. It can be found all over the net called presizer.exe. This program will remove all other parititions and set a new one. Then reformat and you should be in business. Make sure your jumpers are correct for both drives, ie. one must be set to master and one to slave. That's all I can suggest with what you have told us. Best of luck.
As Always,
