• Ensure the drive is recognized:Insert the external optical drive into the computer. After the Windows system recognizes the optical drive, the "DVD RW Drive" icon will be displayed. The Mac OS computer will not display the device icon until the disc is placed in the optical drive and the disc is read successfully. If the computer fails to recognize the optical drive, it may be that the computer's driver is missing or the output current is insufficient.
• About data cable & power cord:1.The USB data cable is built into the bottom of the drive.(Note: The total length of the data cable is only about 10.24 inches / 26 cm.) 2.The charging cord is a separate USB cord that comes with the package. The charging cord cannot be used as a data cable alone, it must be used together with the USB data cable built into the back of the drive. 3.It's better to use the 5V charger/power bank to increase the power if your computer don't have enough power to support the external drive.(Note: For the Apple computers, you need to connect the external CD/DVD drive to the mac/macbook/imac through the USB A/C data cable first, and then connect the 5V charger/power bank to the external CD/DVD drive through the charging cord, otherwise the Apple computer will not recognize the external CD/DVD drive.)
• WINDOWS 11 Requirements:WINDOWS 11 needs a media player (such as VLC ) and a network connection.
• Reading and writing speed: 1.This CD/DVD drive supports USB 3.0 and can provide data transfer speeds of up to 5Gbps. Although it has up to 8x DVD read/write speed and 24x CD read/write speed, the drive reads and writes CD/DVD discs at speeds that increase from the inner circle to the outer circle, and the starting speed is usually lower, reaching the maximum speed when reaching the outermost circle. 2.Recommended speeds (CD: Reading Speed: 24x or lower/Writing Speed: 8x to 16x; DVD: Reading Speed: 8x or lower/Writing Speed: 4x to 8x). For DVDs, slower writing speeds like 4x or 8x are often ideal to ensure data integrity, particularly for high-capacity or dual-layer discs. These speeds allow for more precise data encoding, reducing the risk of read errors in the future.
