Can someone tell me how the dd command handles block sizes?  The man 
page and any Linux books I have don't explain it very well.

If I specify
dd if=\dev\mydevice ... bs=1M
What happens if mydevice has a fraction of a block left over?

What is "notrunc" for the output file?  Truncation from what to what?
