what can i do to get my external hd to show up on my pu? it was working fine 3 days ago from today? this is my second one the first did the same exact thing so i bought another on. i have very important sruff on this hd.
try turning it on then back off. mine was doing that once and i restarted it and it worked. i then copied everything off of it to another hard drive and reformatted it because the problem was persistent. make sure you have your data backed up.
