if you’ve been having continued trouble mounting your motorola droid to your windows xp or vista machine, then check out this quick tutorial. it seems to be helping quite a few people…
For me, I have to leave USB debugging turned on all the time. I have to plug in my
Droid (Motorola), bring down the notification bar, tap on the USB connection, click
mount, then see things not work. At this point, I go into Device Manager, uninstall
three things: 1) ADB Debugging device, Motorola A855 device, and the only connected
USB Mass Storage Device. Next I disconnect my Droid, reconnect it, then bring down
the notification bar, tap on the USB connection, click mount, and it works.
I have to go through the connect, uninstall devices (x3), reconnect, mount process
each time and this works without fail. Simply turning on/off USB debugging does
nothing for me.
Keep in mind, my computer sees the phone’s SD card, it simply refuses to mount the
SD card without the uninstall/reconnect option I’v described above. When I
say “Sees the phone’s SD card” I mean that the SD card shows as a drive (i.e. F:
drive) but refuses to let me open it even after clicking Mount under the
notification bar. Only after the uninstall/reconnection option I’ve described above
can I click Mount under the notification bar and see the drive (i.e. F: drive) and
see the drive become active (not grayed out) and see it’s size and contents.
let me know if you have any questions!
