I have a desperate friend who has a Windows 7 machine into which she installed a Western Digital 1 TB internal SATA drive. The drive shows up in the Disk Management part of Computer Management Control Panel but refuses entreaties to be partitioned, to be formatted, or otherwise modified from its current 'unallocated' state. She tried removing the drive, letting Windows 7 reboot so it sees only the drives it 'likes', and then shutting down, manually reinstalling the SATA 1TB drive and letting Windows 7 try to find it on reboot. The attached screenshot is the result (just as it was before). Any ideas?
