Spoke a bit too soon there...

This is what the using-specialnames bit of the docs reckons (I think)...
$ ./ddrescue.exe -n -v --input-position 121506468b --input-position
121506468b
if=\device\harddisk1 of=Z:\dee.img Z:\log_file.log
ddrescue: cannot open input file: No such file or directory


This is the same but with unix path separators...
$ ./ddrescue.exe -n -v --input-position 121506468b --input-position
121506468b
if=/device/harddisk1 of=Z:\dee.img Z:\log_file.log
ddrescue: cannot open input file: No such file or directory


This is the syntax that worked for dd...
 $ ./ddrescue.exe -r0 -v --input-position 121506468b --input-position
121506468b
 if=\\?\Device\Harddisk1 of=Z:\dee.img Z:\log_file.log
cygwin warning:
  MS-DOS style path detected: if=\?DeviceHarddisk1
  Preferred POSIX equivalent is: if=/?DeviceHarddisk1
  CYGWIN environment variable option "nodosfilewarning" turns off this
warning.
  Consult the user's guide for more details about POSIX paths:
    http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
ddrescue: cannot open input file: No such file or directory
 

This is what the above error suggests...
$ ./ddrescue.exe -r0 -v --input-position 121506468b --input-position
121506468b
 if=/?DeviceHarddisk1 of=Z:\dee.img Z:\log_file.log
ddrescue: cannot open input file: No such file or directory
 

Also if=/dev/hdb didn't work.

I haven't tried windows drive letters as I have the drive unmounted so
it hasn't got a drive letter, likewise df and cat /proc/partitions are
no help.

Any ideas?

Thanks,

Roger.
