mediacheck was removed because it does not work for verifying a LiveDVD.
do you know the underlying reason about that failure ? (seek position > 4 Gb ? )
no, and I couldn't find out why it doesn't work. It is not a problem of the 4GB limit, i.e., it did not work for a 3.5GB liveDVD, seems to only work for up to CD-size. Tried to replace it with checkisomd5, see here, but that didn't work either. A net search reveals that mediacheck is flaky esp. when dealing with DVDs, e.g., here, or here, it could be related to improper padding problem, or a genisoimage bug.
Thanks for info. I read all the links you posted, and ended up to be more confused
So i decided to try the things myself.
The first test was to check mediacheck against pclinuxos-fullmonty-2011.04
(the previous release) and the result was PASS
, i made this test one or two days ago
, later i deleted the 2011-04 iso.
I repeated the test against the remaster of my installation, which I created with mylivecd --gzip as.iso
(approx 3.9 GB), actually the md5sum it's not embedded into the remaster, so I have added the md5sum using the command:implantisomd5 as.iso
and then runned mediacheck as.iso
the result was PASS.
Also, I have burned a DVD
and runned mediacheck against /dev/sr0, result PASS
Finally I made a test using pclinuxos-kde-2011.09.iso
, again implanting the md5sum and then running mediacheck, the result still is PASS
Because of your report in the link you posted...:http://www.pclinuxos.com/forum/index.php/topic,90614.msg759463.html#msg759463
... I have to think that either, I'm crazy, or something is changed in the meantime
(something is changed could be libc.so.6
who has been updated sometime ago, recently).
If you still have a 2011-04 copy of the fullmonty.iso, could you check again ?
Additionally can you try, like I have done, to implant the md5sum into the latest fullmonty and test again using mediacheck ?
