Google is your friend! I was going to post the question below, but found this on Google:
http://www.troubleshooters.com/linux/coasterless.htm#rawread Any Comments? Short question: How can I verify or compare an ISO that I created from a known good CD? Long question: I created ISOs for Red Hat 8.0 from CDs I burnt from downloaded ISOs which checked good with the md5sums after downloading. After burning them, the CDs checked good with Red Hats checkmedia, so these are *my originals* that I wanted to make copies of for my son. I no longer have the downloaded ISOs. I did the dd if=/dev/cdrom of=RedHatDiskx.iso thing and created the ISOs. I then burned the CDs and began the checkmedia routine. CDs 1 and 2 passed and I wasn't going to check the rest but did anyway. CDs 3-5 failed checkmedia. I then re-checked the originals and they all passed checkmedia. So I ended up with 3 coasters, which isn't a big deal but pretty annoying. I looked at man dd and man md5sum. I don't see any way to verify with dd or to create md5sums from a data CD. Did I miss something? Is there a way to verify that an ISO created with dd is valid? Or that a CD burned from an ISO is good? BTW, if it makes any difference, the versions are: md5sum (textutils) 2.1 dd (fileutils) 4.1.11 on a SuSE 8.1 system. Dave __________________________________________________ Do you Yahoo!? Yahoo!
