Thanks again for your reply. I'm going to buy a new box of Verbatims tomorrow (MKM-003 Singapore, 10pcs for €25,-.....). Hopefully that will fix the problem, but to be honest I don't think the Verbatims are the problem. I never had one failed Verbatim over here. This all started out with the Lite-On IHAS 124B.
But it seems those 8.7gb are really needed for some games. So I'm going to test another batch tomorrow. I'll post the results as soon as I'm finished. After that I'm going to reflash my original firmware (thanks for the tip, I made a backup which I forgot ). I still got 4 Verbatim's left at the moment. Is it usefull to try and burn a truncated disc with the original firmware? Just to test if the drive is really no good? Again, thanks for all your time and effort.
Regards,
John
