Has anybody actually used the conv=sync option in the past 20 years?
It doesn't do what you think (that's conv=fsync), instead it pads
short reads with zeroes so the input block size is always the same.
How is that useful?
It's very useful when trying to image dying hard disks, so bad sectors
(that cause short reads or read failure) do not affect the alignment of
the rest of the data in the image file.
