[Bug-ddrescue] Hey. Here is a much needed improvement request

[Asbjørn Holland Christensen]

Hey

I love you work with this program it has saved my as!# on a few 
orcations. Currently i am trying to restore my friends external disk...
I usaly starts with
ddrescue -n /dev/[source] /dev/[target] rescue.log
then i do
ddrescue -dr1 /dev/[source] /dev/[target] rescue.log
That has allways solved my problems... But in this case.

The problem is that at some point the disk fails so that the system 
cannot see the disk any more so i have to shutdown the computer 
completely to regain access to the disk to continue. The improvment that 
i request is for ddrescue to stop when a disk fails like this insted of 
continuing marking sectors as tryed runing quickly over the rest of the 
disk...

If there is a way to tell ddrescue to stop on total disk failure then i 
havent found it. If not then i don't hope it is to much truble to 
implament...

Keep up the good work.
Yours
