USB 8 GB Flash Drive worked fine for over a year but now disconnects moments after plugged in. Tried to plug in the flash drive both XP and Vista operating systems. The PC will issue the tone indicating that it recognizes that a device has been plugged in to USB port and the light comes on indicating power to drive, but PC will instantly issue the tone indicating that the flash drive has been disconnected. Drive info does not appear in Disk Management window and the My Computer screen will briefly show 'Scanning For Object' but the disconnect tone sounds before icon can appear. I don't have a full backup of all information on drive. Is there any way to force drive up long enough to transfer information or any recovery software that I can try?
