USB HP Pocket media drive PDOOOO not recognized

With the drive plugged in, go to Start/Search and type devmgmt.msc Right click the devmgmt icon in the search results and Run As Administrator. In the Device Manager. If you see any devices with a Yellow mark or under Universal Serial Bus Controllers you see an Unknown Device, right click it and Uninstall it. Now unplug the USB HDD and restart the computer. A USB drive that is not recognized is usually due to inadequate power. If it comes with a Dual USB cable be sure to plug in both ends to the computer. Once the computer boots up, plug it into a different USB port, and not through a Docking Station or Hub as these ports are weaker. You should get a new hardware wizard. You may need an optional power adapter or plug it into a Powered USB Hub.
