Afaik, as Android is a derivation of Linux, you might need to unmount
the USB storage properly before physically unplug that. Unlike to
Windows where you will see a progress bar to show the status, writing
data in *nix is that you will see the files appear on the destination in
advance to files written completely.

Just 2c based on *nix, please kindly point out if I am wrong.

2. Emulator could not start - NAND: could not create temp file for system NAND disk image: No such file or directory

VISTA
Android 2.0
Eclipse
I always could not start emulator successfully.
It's hard to understand why the system NAND disk image could not be
created.
Where's the temp file would be created?

Please help!
