Yes you can but it has to be the same as Yamaha uses because not all of them work the same.
There is also a replacement for an flashdisk-drive possible. Cost you 100 US$ + 20 US$ sending by DHL.
I am NOT the vendor but if you are interested send me your mailaddress and I send you a zipfile with all the info from my own experience. It works wonderful!
