perhaps we should do a hardware mod which enhances/replaces power supply/charging circuit :D
i often have run into this problem. because of that, for me, archos jukebox isn`t "real"
external disk-storage. i just can attach it to the pc and upload/download some files. but
i never would use it as a "working hdd"(which would be very fine)
