I too cannot get generic drives to show in the drive tree
in My Computer. I noticed this when I tried to download
vacation pix off my Sony Cybershot DSC-70 digital still
camera. Always worked before. Now when I plug in the
camera to download, the icon to safely remove the device
appears in the tray, everything is happy in hardware
profiles (this device is working, no conflicts, no red x's
or any of that stuff), Sony DSC shows in the USB list, no
conflicts, everything AOK. Just no F: (generic,
removable) drive in the tree with the other drives as
before. No error messages, just nothing happens in the
tree.
I have found by right clicking on My Computer and
selecting "Manage" and then selecting "Drive Manager" from
that tree, I can get my removable, generic (Sony camera)
volume to appear and allow itself to be opened. A few
more keystrokes, but seems to work just fine. Still,
baffled by the sudden change.
The only thing I can think of is SP2 downloaded another
driver for the Sony camera when I upgraded last week. Or a
switch was set during installation? I did notice I had to
re-enter some stuff in Outlook to send e-mail again after
the SP2 upgrade. Could this be something like that?
The switch thing occurred to me because of others who
haven't upgraded to SP2 have the same problem periodically.
I noticed before SP2 that the order in which I connected
the camera to the USB port, powering it up, and opening
Windows Explorer, made a difference in if the volume would
appear in the drive tree.
