Re: [Bug-ddrescue] ddrescue trashed partition table (invalid args not trapped)

What an unfortunate mistake. :-(

The command line above is equivalent to:
  ddrescue --force --no-scrape --log-rates=/dev/sda /dev/sdb mapfile
where infile = '/dev/sdb' and outfile = 'mapfile'.

There are no "invalid args not trapped".

To help avoid these mistakes in the future I'm making two changes to 
ddrescue:
1) remove the short option names '-1' and '-2'.
2) never allow the writing of logs (--log-rates, --log-reads) to devices.

Thank you for reporting this.

Best regards,
Antonio.
