Good morning
Thank You.
Can this help:
https://apple.stackexchange.com/questions/39504/best-way-to-copy-all-files-ignoring-errors,,hotmail
I do not know.
...
I put in a DVD
and try to copy the data to HD
mc is saying:
Cannot copy.
Do You want to ignore the DVD?
I do not know mc, but what you describe is definitely not a full
description of an error. Probably because mc is designed to hide those.
In that case, you'd have to look at lower levels to actually see what is
going on.
I think there was a bug during burning.
One important step in solving problems is identifying the problem.
That latest statement of yours indicates that you have not yet done so.
You need to get beyond the stage of assuming, believing or thinking
something might have happened -- you need to know.
Is "dd" the best idea?
Quite surely not.
Better find out what actually is on your DVD first. I have not worked
with DVD writing for at least 10 years, and I do not intend to in the
future, but I'm sure there are tools that can tell you about sessions
and whatever you can have on the different flavours of writable DVDs.
Once you know that level is good, you'll start to look at file systems.
After that, eventually, files and copying *may* become relevant.
I would propose you just stop spending time on those topics all those
details may not be interesting to you. On the other hand, if the data is
really important, it's time to start learning about how DVD writing
actually works. A mailing list is not going to be very efficient here,
better start differently, for example here:
http://fy.chalmers.se/~appro/linux/DVD+RW/ and follow the links and make
sure ypu actually understand those information. You probably will need a
few packs of writable DVDs because experimenting and failing can be
invaluable elements of learning.
It can actually be fun.
Cheers,
Arno
