Carol, before you go, a couple of things to consider.
1. Like many on here, I've ripped all of my delicate floppy disks to files I store on the PC and/or USB drive so not sure you need to bother testing the USB floppy reader for this instance (hope that saves you a trip :-)
2. The new Enspire pianos come with a USB/Wifi device (UD-WL1) for wireless internet/PC access. In working with the good folks in support this can be problematic compared to directly wiring the Enspire to a Switch or better yet directly to a home router (which is what I do and it works flawlessly). The UD-WL1 often dropped out and may have been due to how much electromagnetic energy that is produced around the drive and component boxes stored under the piano (not sure yet).
In summary, the goal is to put all ripped floppy songs, CD songs, - all Pianosoft music on one USB drive which can be easily accessed/searched/organized by the new Enspire controller box and robust app.
Thanks!
