Hi horsecharles, Thanks for the info, but my problem is a little bit different from theirs. Every time a plug the hdd, it works fine, Windows Explorer maps the drive (I:). If I keep the hdd plugged and (reboot) or (turn off and turn on) the computer, Windows explorer doesn´t map automatically the drive. I have to unplug and then plug the hdd in order to access the hdd. Thanks anyway sgbrito
