OK- gotcha!
There is one pretty easy workaround to getting to the folder, so we can take care of that anyways-- in the Finder's menus you will see one simply titled "Go". That will allow you to jump directly to any folder, with several being pre-defined (including the Applications folder).
Since the Finder prefs for show hard disks is checked, I am going to have to research that one because something posted here recently comes to mind. To check if the invisibility bit has been accidentally set by a Finder glitch, you can tell the System to make sure the icon is visible by entering:
SetFile -a v "/Volumes/
Drive Name Goes Here"
then pressing return/enter in the Terminal application found in the Utilities folder (inserting your specific hard drive name in place of the
Drive Name Goes Here). The quotes are necessary too BTW.
For future reference if you ever want to make an individual drive's icon invisible on the desktop (like simply hiding a Time Machine drive's icon), you can enter the same command, but with a capital V:
SetFile -a V "/Volumes/Drive Name Goes Here"
