Ahah, i'm going to put an extra 2-3K source so i can find an all important 
item like the disklabel, sure thing. :-)

I'd probably chuck all my scanners and Norton disk doctor into a for-next
loop and just watch..:-)

See ? :)

I don't think so, not in C anyway, if you don't catch the harderr 
yourself the dos abort/retry/fail comes up. Not pretty to say the least.
After that, one could extract the doserr info, and see if the operation
was a succes or not, and inform the user, but ideally that should be done
without dos poking in it's ugly face previously.

Ps: Ralph's new interrupt list is out. You can get it at:
