Hi,

Welcome to LQ!

The 'md5sum' or 'hash' is very important to learn to use and too regularly get in the habit of utilizing it. You can get a sum checker for M$ Windows if need be; 'md5sum.exe'.

For GNU/Linux the 'man md5sum' will get you all the information to perform the check. You can get the 'man md5sum' from the 'cli' at anytime.

If you downloaded the CD/DVD ISO then be sure to check the md5sum for the original ISO. From the cli;

Code:
~#cd /downloadisolocation      #cdromiso.iso cdromiso.md5
~#md5sum -c cdromiso.md5       #substitute the correct name to check
If the ISO md5 is OK then you should check the image burnt with 'CdromMd5sumsAfterBurning''.

This way you will know if the burn was OK!

This will check the download ISO with the known md5sum that you also get with the ISO. You should do the check for any download that you might perform, even a LiveCD. Plus burn the image. Then be sure to check the burnt image you created. Sometimes you may need to lower the burn rate to get a valid burn.

i checked my md5sum and the iso. They were both fine. So next i tried to the disk on a different computer. it worked! but not on my computer.. i have a new sony vaio and the computers that it worked were an old dell latitude and another sony vaio. Im just stumped to why it loads fine on other computers and on mine it comes up with errors. Any advice would be grand.

Hi,

Why not try 'ADRIANE-KNOPPIX_V6.2.1CD-2010-01-31-EN.iso' to see if it is a hardware issue with recognition.

Don't forget the 'ADRIANE-KNOPPIX_V6.2.1CD-2010-01-31-EN.iso.md5' and be sure to perform the checks for the download along with checking the burnt image. You may need to slow your burn speed to insure a valid burn.
