This is a clone stand from Cyberplugs. I purchased it used. I've used it several times, and it works without any problems. It only has a clone function and no error skip function. Would you be interested if that's okay? It's a dual hard disk drive with USB connection and LED indicators. - Model: Dual Hard Disk Drive - Interface: USB connection - Power adapter: Included - LED indicator: HDD usage status display - Manual: Japanese manual included
