|I recently installed Win 7 on a new drive along with XP Pro SP3 which is on another drive. I've had XP installed for a long time without USB issues. After I install Win 7, most of my USB drives say they need to be formatted (both in XP and Win 7). The USB devices work in any other PC and they worked in XP before I installed Win 7.|
The XP and Win 7 installations both work fine aside from the USB issue. And Win 7 was installed after XP to note.
