Hi Ed, the only way I know of confirming Tyros HD free space available is from your PC, with the Tyros connected via USB cable to the PC and booted up in USB-Storage Mode (HDD) mode (holding down the MusicFinder button while turning on the Tyros keyboard). The Tyros HD is then seen (in Windows "My Computer" as an external device. Double click on: 'My Computer' located on the the PC desktop. highlight (with your mouse) the icon that represents the Tyros HD and both HD capacity & free space available will appear on the left in details box. - Scott
