coverup Posted December 7, 2006 Report Share Posted December 7, 2006 I am trying to install Mandriva Free 2007 from a DVD which came with one of the magazines (Linux Format IIRC). It gives an error during install and aborts, alt+F4 shows some media errors. How can I check whether the DVD is damaged/defective? There is a file called MD5SUM in i586 directory, but it is empty...

coverup Posted December 8, 2006 Author Report Share Posted December 8, 2006 doesnt the tips here work? ciao! I am lost. The caveat specificly instructs that the command $ md5sum /dev/cdrom should not be used :huh: Instead one should use some info about the iso (the length of a particular ISO image). But I did not burn the DVD (I bought it), how do i know the length of the ISO? Now, even if I did know it, where can I find the correct md5 sum to compare with? Sorry if it all sounds like a bunch of nonsense, I just want to get two numbers and compare them in a simplest possible way... Quote Link to comment Share on other sites More sharing options...
ramfree17 Posted December 8, 2006 Report Share Posted December 8, 2006 if that media is burned from the MDV free version then you can get the sum from any of the mirrors. if that is not the case then you could ask the magazine where they got the source they used for manufacturing those CDs. the caveat just means that if you get a different hash if the installer was burned with padding bytes. if not then the command would return the same hash if the media is good. ciao!

coverup Posted December 10, 2006 Author Report Share Posted December 10, 2006 md5sum /dev/cdrom gives me input/uoutput error. I guess the DVD is dead. Quote Link to comment Share on other sites More sharing options...
ramfree17 Posted December 11, 2006 Report Share Posted December 11, 2006 does it mount at all? if not then i would agree that the media is dead. ciao! Quote Link to comment Share on other sites More sharing options...
emmanuel_uk Posted December 11, 2006 Report Share Posted December 11, 2006 md5sum /dev/cdrom gives me input/uoutput error. I guess the DVD is dead. nop could be /dev/cdrom1 or /dev/dvd if you managed to partly install, then the cd should be partly ok at least sometimes cover disks are warped, or not well balanced, can cause trouble Did you test it on another PC? alt+F4 shows some media errors. exactly what message. From here it sounds like dirty or wrapped cd. Is the error random after 2 or 3 installs? Quote Link to comment Share on other sites More sharing options...
