If Windows was on the drive before then 7 won't see it on some occasions depending on the drive state. Something to do with MBR/Partition tables.

Just wipe the drive clean using a Windows XP CD to boot with but don't run through XP setup - the drive should show up in 7 setup afterwards allowing you to create a new partition.

yes there was windows vista installed before and this drive was used in raid 0 before so , cleaning it with xp might work ill do that in a bit,

im using asus crosshair 4 formula and HDD is raptor x 150gb , mob has sata 3
