How to burn the iso - an interesting note

While translating packager.pot (part of YaST) I saw this recommendation:

+++···················
If you burn the media yourself, use the pad option in your recording
software. It avoids read errors at the end of the media during the check.

i wonder if that instruction has been there for years…and, maybe is no
longer valid

or

if it was recently added and is VERY valid, important to know and
imperative to use…

plus, i wonder if it applies to all of “your recording software”?
K3b, Nero and cdrecord???

for example:

man cdrecord | grep pad

finally, if new and very important i’d think it ought to be written into
http://en.opensuse.org/SDB:Download_help#Burn_the_ISO_image.28s.29, as
well as to How-To forum, and probably somewhere in
http://doc.opensuse.org/documentation/

Good point. The translation software only presents to me new messages or
messages that have been modified. In this case, it was a modification, I
have seen the message in the 2009 version.

I think it makes sense, because it is a known error when comparing images
to the CD reading beyond the last byte of the image. In fact, I have a burn
script that does a compare of the image like this:


cmp --bytes=$(wc -c <$1) /dev/dvd $1

where $1 is the image: it only compares the exact number of bytes of the
image, because the DVD is rounded up to a sector, and comparison fails.

I think so.

for example:

man cdrecord | grep pad

Probably…

In any case, if you tell k3b to compare the image to the media, it will
work correctly, because it does something similar to what I do.
