All brands of hard drives are standarized and very generic.  CAVS DVD Karaoke players are compatible to most, if not all,of the brands.

However the USB external cases that encloses the hard drives are not standarized in any sense.  There are many different manufacturers and it is hit-and-miss dealing with them for the compatibility to CAVS DVD Karaoke players.

We are currently using the following hard drives:

• All hard drives enclosed in iMicro USB External cases
• Seagate Free Agent
• Iomega Silver Series

We recommend avoiding the hard drives of following specifications:

• Over 1 TB (we have successfully tested only up to 1 TB)
• Additional functions (such as 1-touch Backup, Power saver)
• No self power supply (for 60GB or more)

Note: Compatible USB external hard drives (250GB, 500GB, 750GB, 1TB) can also be purchased at CAVS USA Inc.  Please contact sales@cavsusa.net.
