My rig: Duron CPU 1.1 gig/Win 98se/ECS K7S5A/256Pc133/Antec 450 watt P.S./ Primary Master: WD 20 gig 7200 ATA 100/Secondary Slave: none/ Secondary Master: TDK CD Burner/ Secondary Slave: Delta CD Rom. Set Up: C: WD 20 gig (running Windows 98se and programs) D: Maxtor 30 gig 7200 ATA 100 (for storage) attached to ATA 100 Promise controller card. Have a brand new WD600JB HDD (60 gig ATA 100) in unopened antistatic bag. Want to install it as Secondary Master on controller card and also use entirely for storage. Must I use Fdisk and create one big partition first? Why can't I just format it through DOS or Windows? BTW, my system is currently using FAT 32 on my Primary Master. Any help or advice would be very much appreciated. Thanks for such a helpful forum...awesome!!
