W7 can't find hard drive

Hello,
I recently added a new SSD to my MacBook Pro. I am running Lion and Parallels 6 (Build 6.0.12094) and have installed Windows 7. Things sync up fine with the new SSD (which is installed in my old optical drive slot). But, from Windows Explorer, I can not find the old hard drive (HD).

Under "Computer," three drives are listed as follows:
Local Disk (C -- this appears to be the partition on which W7 is installed
Home on 'psf' (Y -- this appears to be the new SSD
Home on 'psf' (Z -- this also appears to be the new SSD

I can drop a shortcut onto the SSD desktop that points to files on the old HD and Windows will get me there, listing as a filepath:

Network > psf > Host > Volumes > (name of my old Hard Drive)

Under "Network," the following is listed:
>psh
>
> Host
> (then a bunch of folders, none of which are the "Volumes" folder that comes up in my shortcut described above.

This all matters because I need my programs that I run in W7 to be able to utilize my file storage on the old HD. Right now, outside of the shortcut method, there seems to be no way to save or retrieve files between W7 and my old HD.

Any ideas on resolving this?

Thanks,
Austin
