My 2 cents :
What would constitute an "empty" part ? Sometimes, blocks filled with
00 or FF or any value may be legitimate parts of a file.
To know which blocks are really used for files, ddrescue would have to
analyse the filesystem allocation and, at least to me, that seems to
disrupt the idea of cloning the disk.
You could specify. Usually you can see it quickly enough when you're
recovering the drive; so you could provide a sample block or
byte-sequence for ddrescue to match against, and ddrescue defaulting to
just a full block of 0x00.

Hi Cameron,

Skipping the empty parts of the drive will have to wait until 1.23. I
also will need more feedback about how should ddrescue decide if a
block is empty.
Thank you very much for your donation.
Best regards,
Antonio.
