[Bug-ddrescue] ddrescue on BSD vs Linux

[luminair]

Hi Antonio, re:
http://en.wikipedia.org/wiki/Dd_(Unix)#Recovery-oriented_variants_of_dd

It says "Linux lacks "raw" disk devices like *BSD has, which makes it
less desirable for low-level data recovery," is this true, or just
FUD?  Should I use FreeBSD when I try to recover my disk?

Also, there is a recommended procedure there, of ddrescue -n and then
ddrescue -r 1 afterwards. Is that your recommendation? Otherwise what
is the good of it. You can't trust wikipedia unless the expert wrote
it.

Thank you gentleman!
