For everyone out there that has lots of CDs stored on their Yamaha MucisCAST MCX-1000 or MCX-2000 - MAKE A BACKUP!
Many of these systems have hard drives that are getting old. When the drive fails, you'll be installing your CDs again. Or, clone the hard drive. I use my Aleratec HDD PortaCruiser to clone hard drives from proprietary OS systems like TiVo and Yamaha MCX-2000 as well as Mac and Windows platforms. They all work perfectly - the hard drives are identical and interchangable. These cloning machines don't care what is on the hard drive, they just copy each bit of data from one drive to another making an exact copy. The partition remains the same regardless of hard drive size. There are tools to fiddle with repairing data and changing partitions, but I never mess with them. This tool, and ones like it, make a clone of the MusicCAST hard drive overnight.
Never, never access your MusicCAST hard drive with any OS as it will render it useless!
