Selling due to moving and decluttering. Used for several years, then stored in a dark place. * No setup guide included. * Please check the Buffalo official website for compatible OS. In my amateur opinion, it's in good condition with no scratches, but please refrain from purchasing if you are sensitive to such things. This is a compact external DVD drive. M-DISC compatible, supports Windows and Mac. - Brand: BUFFALO - Model: DVSM-PLV8U2-WHA - Data storage method: DVD - Supported OS: Windows, Mac - M-DISC support: Yes
