Mac hard drive missing from "My Computer"

Hello. I used to have a "External hard drive (X" (Or something like that) that would allow me to access my Mac hard drive & files so I could import them over on to the PC side. Since upgrading to Parallels 9.0.2, it has gone missing. Even my external Western Digital HD is no longer available or can be found on the Parallels side... Any ideas why it has all of a sudden vanished? Thank you!

 

Reinstall Parallels Tools.
