When I boot up Windows, and open My Computer, it only shows D:
(and A: and other normal stuff), not C:. But, I can type C:
into the "Address" bar, and then I can access it fine. If I
go into the Device Manager, and open up Disk Drives, I see my
drive, and if I select Properties/Settings it shows "Current
Drive Letter Assigment: 'C:,D:'.
So everything seems fine, except that C: doesn't show up in
My Computer... It shows up in the Scandisk menu just fine
and scans with no errors.
I've carefully checked and it's not just that the icon has
another icon on top - I've set auto layout, detail view, etc
and it's just not there. The My Computer folder has "View
Hidden Files" set so I haven't somehow hidden it. I'm
mystified. I've also run Norton Windoctor and it didn't come
up with anything.
