Im not sure if Windows 95 supports FAT32? I know Windows 98 should make it one big partion without any problems. Not sure for Win95 but you can with Win98. With win95 I think you can but will have to use a floppy that comes with the Drive and it will let you partion the drive. Some BIOS only let you go up to 8 GIG I believe it is. So you might need to flash the BIOS, but I wouldnt mess with it unless you know how to flash your BIOS. Most drive come with a floppy to help make bigger partions. I might be way off here, its just been so long since I have to setup and H/D is a older system.
Good Luck!
