Folks,
Can anyone help me please? I have a kn3000 with the optional hard disk from technote and I need to format it as I am going to sell it and I have a lot of "stuff" in there which I have backed up and do not wish to let go with the keyboard. Formatting would be a lot easier than going through each folder and deleting each file one by one. Also, can the kn3000 be infected by computer viruses? Thanks in advance for any help you might be able to afford on this.

It's been a very long time ago, with many keyboards in between, so memory is hazy, but I'm pretty sure the standard hard drive did not have a user format, so you may have to delete.
I converted mine to the Keysoft system with direct communication to the laptop from hard drive, and that did have a format available.
Viruses, no or unlikely in the extreme, since they are written for windows or dos and are meaningless to a kn operating system.

I had that keyboard and was never able to find a way to format the hard drive. Just erase was all.
