I have a 2GB Sandisk microSD card in my 8800 which can be read and written to with the BB Desktop Manager.
Once I enable "Mass Storage Mode" on my BB it will ask for a password after plugging in the USB cable. I enter the password and both of my PCs (Desktop and Notebook) crash with immediate reboot or freeze. Even no blue screen of death.
Anyone has similar experiences and or a solution?

im using my 8800 on vista with no problems in mass storage mode...

as soon as i plug it in, my bb asks for my password and then it pops up as a drive...not sure what would be causing it to happen for you. sorry.
