Before you rma that drive:
1. Disconnect the working drive,
2. Connect the new drive to exactly the same cable, etc that was used by the working drive.
3. Boot up from you Windows 7 DVD.
4. Odds are that you will have success.
If before you do that you would like to try another disk utility, then I recommend: Hitachi Drive Fitness Testhttp://www.hitachigst.com/hdd/suppor...2_v416_b00.iso
tests SCSI, IDE and SATA drives
without overwriting data
Simply dbl-click on the .iso file you download and the WinDVD burner will prompt you to insert a dvd/cd.
Boot from the cd/dvd you just burned.
