I have a 360G ext hard drive which I formatted, partitioned and used to backup both my laptop and desktop aabout a week ago. Now when I plug it in to my same laptop or desktop, neither of them seem to see the drive--tho the laptop makes a sound when plugging in the USB connector. Ext drive is humming away and has an indicator light that suggests it's getting power thru the USB port (I've tried 2 or 3 ports on each computer) so I think the ports and the cable are OK. This is driving me crazy! After the backups, I was able to see the files on the ext hard drive and access them on both computers, but not now.
Thanks for any help.
