I have the same problem as Tanglust.. Do u have the solution for this problem? Thank u. Problem:posted by Tanglust on Jun 30, 2006Report abuse Got this message "internal memory unknown format". Went to Rio's site, 1st suggestion is reformat drive -- not able to because drive is not recognized. 2nd option do a flash. The flash software does not see the rio. I double checked all the drivers, they are all working fine. But description of drive is unknown. I just upgraded to windows xp professional. And it shows as two different storage files. I am soooooooooo confused can you think of anything else I can do ?
Turn it on holding the MENU button, connect the usb cable and update the firmware that u can download from www.rioaudio.com, that will fix it.

I did the above and it still is giving me the error. I am using firmware update 1.33.
i cant put the music on my mp3 player because the internal memory is too small!
