I am still having problems with Yamaha File Utility. The internal HD of the TYROS doesn´t appear on the list. I have even installed the Windows XP and all drivers again, but still the problem appears. This is very annoying. Some people say that the File Utility is useless, because you can use the USB transfer mode (if you have OS 1.20), which is much faster, but I disagree. With USB transfer mode you can not backup your registerations and other stuff directly. That´s why I would need the File Utility, but it doesn´t works. Yamahas software has always been very poor.
