I just purchased a WD 1TB drive to replace my Hatachie 320 MB drive. The dive has been formatted with three primary partitions (the small one that Win 7 puts out there) plus the two I did. One will be for Windows 7 and one will be for Windows 8. I can see the drives when I go through Control Panel/Admin Tools/Disk Management. I can even open and move around in those partitions. However, the partition for Win 8 will not show up when I access my computer from Start/Computer when I'm in the Win 7 OS. I'm waiting to reinstall Win 8 until I can get this fixed. I've got a system image of the entire hard drive "just in case" it tanks again. I want to know why I can't see the Win 8 partition from Win 7. There was no problem like this on the Hatachie.
