Hi and Welcome![QUOTE=mycesteve;2663639]I need a Powerspec hard drive inclosure IDE to USB cable driver for Win 2008 Server. Please advise. [/QUOTE]Usually, drivers for IDE/USB bridges are already part of the operating system. If the device is not recognised, it might be defective or there is some misconfiguration of the OS.
Please try the device with another computer, also you should try another OS (Linux Live CD) on the original system.
Additional possibility: You are not permitted to add storage devices. Then contact the system administrator.
