Another tip for avoiding the use of disks is to install a hard disk image. You can do this through the hatari configuration menu.

1) Download a blank hd image: http://hatari.berlios.de/download.html
2) Extract the hard drive image to a location on your PDA. (warning - its 80mb)
3) Press the Menu button to bring up the configuration page.
4) Under the disk menu, point the HD image to the image you extracted.
5) If you were successful, you know have a c: on your desktop.
6) You can now copy any disk you insert onto the hard drive! No more disk management.

I have also attached a blank HD image to this post. Have fun!
