Thank you very much.

It would be useful if you could confirm that using '--reopen-on-error 
--min-read-rate --idirect' improves the read rate (or not).

If these options do not improve the read rate, it may be that the kernel 
is caching information about the ddrescue process and is not forgetting 
its internal settings on the file descriptor corresponding to the input 
file when ddrescue reopens it, making it necessary to restart ddrescue.


Best regards,
Antonio.
