Re: Tools to repair corrupt ProDOS filesystem

[Dennis Jenkins <djenkins@usb.com>]

	I periodically mirror my drive by hooking it up to my SCSI chain on my
Linux box and then I do a "dd if=/dev/sda1
of=/root/backup/appleiigs.img".

	What is neat is that I also run Basillisk II (a mac emulator) on my NT
box at work.  I installed the ProDOS mac os extension.  I can mount my
ProDOS disk image in my virtual mac and move files around using the Mac
Finder. :)

The three most dangerous things are a programmer with a soldering
iron, a manager who codes, and a user who gets ideas.
