4k Discs keep getting scratched during burn

[xenith]

I recently bought these three drives because they are the recommended ones to get
LG WH16NS60, UHD Official Internal 5.25
LG WH14NS40, UHD Friendly Internal 5.25
Archgon MD-8107S-U3-UHD, UHD Official, External Slim 9.5mm

These are all using the recommended firmware for these drives to have it run libredrive. Unfortunately I've had terrible luck with them all scratching the 4k blu-rays only inner circle area. Has anyone else experienced this?

scratches in the center like that dont matter.
all the drives should have a rubber pad on the center there you will be able to see it on the BU40N the rest are harder to see.
mine all have a rubber pattern imprint on them

Hi Billy,

Thanks so much for replying. I was worried this was a faulty drive, if this is the normal then so be it!
