I have a Vista 64 bit laptop. Got a droid eris 2 weeks ago or so. First time I ever wanted to connect my computer and phone I tried a bunch of things but each time, phone kept saying it was mounting but then would never do it. BUT under settings/SD it knew it was mounted b/c of card size, etc showing up and "Unmount" was selectable. Did lots of things, kept trying, eventually when I tried out the sync feature found out I didn't have HTC sync on my computer, which it said it needed, so I installed that and then tried to mount again and then it worked! I viewed my files, moved some pics around, etc. Now I go to mount again and the same thing is wrong... won't connect at all. Tried mounting, unmounting, power cycling, using device manager on my laptop, even took out the card and put it back in, safely removing hardware, back and forth and on and on. Computer knows it's plugged in because it shows up as drive F but when you click on it once it is "mounted" (though I don't think it actually is mounted) - the computer says "please insert disk into drive f". I have USB 2.0 and I got it to work once, I don't understand what is wrong this time! Suggestions?
