check you’ve got the right volume. IME phones (esp. Android phones) mount two or three drives when you plug them in, one presents as a CD drive and has the carrier or phone manufacturer’s drivers/software on it and is read-only. the other(s) is/are the phone’s actual storage.
Odd. The Droid X doesn’t even bother mounting the system partition. It just maps internal and external storage.
You may also want a program called Android Manager Wifi, which, as the name implies, allows you to use your Wifi connection to transfer files and stuff. I found it much easier than of the other options.
Anyway, I did figure it out. It gets mapped as two drives. At first I did not see that and the drive I was trying to open was read only. The other ‘drive’ has all the system folders and such.
I’ll be getting a droid in a few months. That will give me some more time to mess around with it (my Wife is very busy and I really don’t have access to her phone)
