check on the back of your hardrives to make sure you have the jumpers set right
not to say RTFM but read in the manual about your jumper settings
Negatory on that, good buddy. Windows sees the drive. The drive is there. The drive has no partition information. He needs to create that information. :)
Sethro, you have to partition and format the drive for it to be usable.
Right-click the drive in Disk Management, and click "Create Partition." Use the NTFS allocation, default settings. When that is finished (short time), you will have a ~120 gig partition available to format.
To format, again, right-click the drive, click format (will take a good, long.......long, looooooooong while), and you're golden.
