All systems may not meet USB power requirements and full performance may not be achieved. In this case, connect to the USB 2.0 Y type cable (not supplied). The M-DISC uses a patent rock-like recording surface instead of organic dye to etch your data onto a disc By removing the complexities of the disc tray weve simplified the drive to operate in tight spaces and run silently without needing to open or close
