Hello Gene and everybody

With respect to this seemingly useful check procedure:

> Do your own verifying by looking at the filesize of the iso you have
> burnt and dividing that by 2048, the std block size for optical media. > Then use that number in a statement somewhat like this:
> dd if=/media/cdrom(or whatever it is) bs=2048 count=the number you
> got from the division ....

Is it also possible to carry out such a check before finally, really
burning the CD?

With respect to MD5SUM....

> ..use a pipe or whatever to feed it to md5sum.  If the burn is
> good, it will match the md5sum of the source iso file.

Please, explain. Should the number coming out of the division of the
check mentioned above, need to equal the MD5SUM number?

Clear. OK.

Till quite recently the drive seemed to work quite well, also in
combination with K3B. So I first try all possible other options before
thinking about 'binning'.

However it may be, thanks for your advise.
