I cannot understand what's wrong, I've tried other amigas and other printers
but the effect is always the same ....

If I try to read my external drive then I get 'You MUST replace volume BLAH in
drive DF1:' or other such stuff.

If I try to write to df1: then all hell breaks loose and the disk gets so
completely shagged that diskdoctor can't recover it and I need to reformat it.

All this just because the printer is connected but off !  Soon as I unplug it
or switch it on - the problems go away.

PS: I've checked the lead and the +5v isn't connected - just in case you 
wondered.

Whats the problem people ?

Thanx in advance
