If its a PS2 and you have a modchip you need a boot disk to boot the system to run a backup........

can you give me anymore info about the mod chip.........

If its a PS1 - the external chips are very temperamental.. you need to try some other software to copy a burn to make it work right..... you have to understand what you are writing to disk.. sometimes the cd may correct some errors in the origional game making the backup different, therefore a coaster !...

I use adaptec easy cd creator for PS1 backup and
clonecd for PS2 .....

it sometimes depends on your writer... what type is it?
