Hi,
Your post is unclear. Are you having difficulty accessing the drive during
setup? Or have you added a drive to an existing installation and cannot
locate it in Windows Explorer?
If during setup, you may need to add a manufacturer's sata driver via
floppy, CD, or thumb drive at the point where you choose the installation
location prior to creating the system volume.
If to an existing installation, you likely need to run disk manager
(diskmgmt.msc) and create a volume by right clicking the unallocated space,
then format it before you can use it for data storage.
