So far, pre7 runs at 85kb/s while pre6 ran at 65kb/s. Might just be due to the structure, but yeah, faster so far. > I do not maintain ddrescueview, but surely Martin is reading this. ;-) Yup, that was what I was counting on. If he doesn't show up, maybe I'll write him separately later. It is a pretty sweet tool, but there are a few simple (and I think non-controversial) changes that I think could improve it. cheers, David On Sat, Feb 1, 2014 at 1:21 AM, Antonio Diaz Diaz <[email protected]> wrote: > David Deutsch wrote: >>> >>> It could also be useful to have the final logfile to see where are the >>> unrecoverable errors. >> >> >> Alright, I will try to keep that in mind.
