I wrote a program which goes from "Blitz" mode to "Amiga" mode and then back
to "Blitz" mode.  When I ran the program, I got a guru.  Now whenever I 
boot-up my Amiga I get the following message:

	DH0
	has a checksum error
	on disk block 21543

So what's wrong with my Amiga now?  Is this a serious problem? And how do I
fix it?

Thanks in advance (A LOT)
