Curious if anyone else has this problem, when I try to move big files off of a USB drive to MyDocs with h-e-n I will get between 30 to 100 Mb moved and the drive will come unmounted, sometimes the N900 will even shut down. I am guessing it is an electrical power supply issue from getting the flash drive to send data so fast as well as writing to the internal flash. Is there a way to limit data throughput rates when running a drive mounted with h-e-n to avoid these issues?
