Thx for your ddrescue prog.
You are welcome. :-)
*Can you suggest how I fix error*
"*ddrescue: Bad or missing numerical argument*"
after running command
sudo ddrescue -d -o allow_root SDCARDmountPt SDcrdIMAGE SDcrdLOGMAP
I guess you are using an old version of ddrescue because latest ddrescue
(1.27) prints a more informative message:
ddrescue: 'allow_root': Bad or missing numerical argument in option '-o'.
The problem is '-o allow_root' because '-o' requires a numerical argument:
http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Invoking-ddrescue
-o bytes
--output-position=bytes
Starting position of the image of the rescue domain in outfile, in bytes.
Defaults to --input-position. The bytes below bytes aren't touched if they
exist and truncation is not requested. Else they are set to 0.
Removing '-o allow_root' should work and make a copy of the sd card (but I
can't be sure if this is what you intend to do):
sudo ddrescue -d SDCARDmountPt SDcrdIMAGE SDcrdLOGMAP
Hope this helps,
Antonio.
