Is your SATA HDD a new install? If so, you may need to partition and format it before windows can see it.
If it worked and now it doesn't, try checking out Device Manager to make sure nothing else is conflicting. I've seen problems like this with Virtual Drives sometimes.

1) The drive could be corrupted.

As mentioned, first try Disk manager.

If no go then I would try to put hte drive in another machine,  or an external case with USB.

The drive could be failing so you might want to run vendor diagnostics.

UBCD has most of these diagnostics and is free.

I hope this helps !

Are you booting off this SATA drive?

If Windows is booting from another drive, and the SATA drive you cannot see should be D:, it could be that you do not have SATA drivers installed.
