I recently bought a Seagate ATA 250 GB HD (internal) set the jumpers to master and installed it in a Comp USA enclosure to be used as a backup. HD uses USB connectivity. When plugged in the LED in the enclosure has a constant red on top and a slow blinking green on the bottom. When I go into the system hardware the new HD shows up under "USB mass storage" but has a yellow flag next to it. When I double click this, up pops a box that says this device can't start, code 10. I've used the Seagate disc to facilitate the installation, no luck. I've uninstalled and reinstalled the HD , same outcome. Not being the brightest bulb in the box leaves me at a disadvantage. All techno help appreciated.
