I got a 1tb external hd resently. Like this one http://www.amazon.com/Passport-Portable-External-Drive-Storage/dp/B006Y5UV4A/ref=sr_1_2?ie=UTF8&qid=1358012436&sr=8-2&keywords=1+tb+western+digital
from time to time if my computer is restarted the drive doesnt show up in my computer until i discconect and reconnect the usb cable. I have another 500 gig passport that works w/ no problems at all.
anyone have any suggestions?
