I recently rebuilt an old machine previously running Windows 98 (now running Windows 2000 SP2). It has an Aladdin GA-5AX motherboard and two hard drvies both attached to a PCI Promise Ultra66 controller card. Now the problem is, I am unable to get Windows 2000 to analyze or defrag the drives, yet formatting, checkdisk, and the like all work fine. Anyone have any ideas why this would be happening?
