I've just downloaded the latest Mandrake community release and I'm having trouble burning the ISO images to CD. I use K3B and select "Verify Written Data" and every time I get an Error " data does not match". I've tried lowering the speed to 4x, checked that the CD-R is big enough, cleaned the disks but I've had no luck.

I've burned other data CD's before and never had a problem but I'm at a loss as what to do here.

I've included part of the log just in case it is relevant.

Track 01: 694 of 695 MB written (fifo 100%) [buf 99%] 4.1x.
Track 01: 695 of 695 MB written (fifo 100%) [buf 99%] 4.2x.
Track 01: Total bytes read/written: 729139200/729139200 (356025 sectors).
Writing time: 1193.402s
Average write speed 4.0x.
Min drive buffer fill was 99%

Fixating time: 64.690s
/usr/bin/cdrecord: fifo had 11485 puts and 11485 gets.
/usr/bin/cdrecord: fifo was 0 times empty and 11407 times full, min fill was 92%.
BURN-Free was never needed.

cdrecord comand:
-----------------------
/usr/bin/cdrecord -v gracetime=2 dev=/dev/ide/host0/bus1/target0/lun0/cd speed=4 -dao driveropts=burnfree -eject -data /home/simon/Desktop/Mandrakelinux-10.0.2-community/Mandrakelinux10.0.2-CD1.i586.iso


Any advice anyone?

The command line usually works fine. GUIs just provide limited front ends for these tools.

How about CD copying, ripping and burning? I can't figure it out.
# CD burning copying ripping info
Is it configured and what is the device? Command this to find out:
cdrecord -scanbus

I am having thet exact problem with Mandrake, however other iso's burn and verify correctly (ex...Suse)

I see the list od cdrecord commands to burn an iso, but is there a command to VERIFY that the iso burned correctly? That is the main reason that I am using K3B right now is for the verification.
