How do I activate my ATA hard drives?? I've got a 200Gb computer with Win-XP SP2 & 2Gb RAM . I mainly use it for my graphic design and now I'm starting on editing videos and 3D modelling (using AutoCAD & 3dsMax 8). The problem is that I'm starting to run out of spaces in my hard drive (HD). My computer has connections for ATA drives and I've bought 2 two 200Gb HD. But when I go to: Computer Management > Disk Management I can only find the HD that are connected through IDE there but not the ATA ones. How do I go about doing this?? Please any help would be greatly appreciated.
