Subject: update on help! Bdos error on B: R/O

Thanks to all who've responded so far.  I wasn't very clear in stating
the original problem.  I get the above error message *when I haven't  
changed the disk in drive B*.  Sometimes I've just completed a PIP and
I know there is lots of space left on the disk.  My suspicion is that 
the write protect switch is acting up because if I stick my finger in the 
drive slot and jiggle the switch, the problem *sometimes* goes away.
And sometimes it doesn't.  An alternative that occasionally works is
to push the disk in and out of the drive a few times.

I've had this happen earlier today, and had to shut the system down
because I couldn't write to drive B, even after ^C'ing many times
and rebooting (and cursing and yelling....).  

Is this a hardware problem or something in the bdos/bios (I think I've
got the sources).

Thanks again,
dan davison
