I have a desktop pc whose OS is windows 7 and a laptop whose OS is win exp prof. i bought a HP 4 gig flash drive. It works fine on my desktop, but when I plug it into my8 laptop, and try to view it in My computer, although it sees the drive as F, but when I click on it, it says to insert the disk. I have checked in the Device Manager, and there are no errors. Hope someone could give me some tips on how to troubleshoot and fix this problem. Thank u.
