I purchased a used Tyros about a year ago, but I have hesistated using the USB connection because of the problems that I read about it.
I added a hard drive shortly after I bought it and the Hd has worked great. But I am now at a point were I would really like to use the USB but I am concerned that I may lose what I have saved on my HD. Is it possible that I may lose all my info or is it that it just won't transfer info back and forth.....?
I am really ignorant when it comes to issues like this so any guidance would be appreciated.

Regards,

Ed
