I/O error when booting into XFCE LiveCD

[cypherpunks]

I tried the XFCE LiveCD for Fedora 11 and when I try booting into the LiveCD, the screen goes black (text output) and then theres this message:
end_request: I/O error, dev sr0, sector 1383840
Buffer I/O error on device sr0, logical block 172980
It repeats nuerous times before changing to:
end_request: I/O error, dev sr0, sector 1383840
Buffer I/O error on device sr0, logical block 345960
Buffer I/O error on device sr0, logical block 345961
Then this message repeats for a while. I haven't waited longer.

I tried burning my CD at a slower speed but the same errors appear.

Any ideas?

I have the same sort of error using the KDE liveCD too. Same error, different sector. It gets to the screen saying 'automatic boot in n seconds' and then when the count down runs out it just cycles the error message ad infinitum.

end_request: I/O error, dev sr0, sector 1320288
Buffer I/O error on device sr0, sector 165036.

I checked the checksum and it is correct for my ISO but haven't reburnt the CD at a slower speed yet as cypherpunks implied it didn't help.

I can boot Fedora 10 fine and any other version of linux I have tried, OpenSuse, Mandriva, Ubuntu, Mepis, LinuxMint, Wolvix, PClinuxOS etc.

I am getting the same error but different block numbers using the standard Gnome Live CD.

I'm running it on a Dell Latitude D630 and E6500, and in a VMWare virtual guest on an E6500. After about 15 min of that repeated buffer error on the E6500, it finally did boot, but it ran extremely slow (unusable).

It booted just fine on an IBM R51 Thinkpad though, so it appears to be some sort of hardware or BIOS related error.

Are you guys running on Dell machines?

No I have a home built desktop Intel Core 2 Quad 8300 with an ASUS motherboard I believe and Nvidia 9600GT graphics card.

My computer is home built too. It has an Athlon 64 X2 and ECS motherboard.

I downloaded the iso again, and burned it using K3B instead of the Gnome CD Writer and that seemed to make the difference. Either the download was corrupt, or K3B has a more robust iso burning utility.

I decided to burn the ISO with Xfburn instead of Nero Linux and it worked. Thank you so much for the idea!!!

The first time I burnt it I used Gizmo burner on Windows XP so I retried using Nero 7 on the slowest speed it could, 8x. I got a bit further along with the loading bar coming up along the bottom of the screen. It reached the end and the text saying Fedora went from blue to white and then the screen went black and it just sat there forever. I think I will just give this one a skip and try again some other time.
