Help pls..losing faith on my Ldw811s

Hello

after burning dozens of disc and toying with different FW, software & media,
my 811s is only able to burn good quality (PI<100,PO<10) at 2.4x
and with size up to ard 4GB.

the biggest problem is burning disc with size of 4.2GB or bigger,
almost all turn out not readable or recogniseable on my 811s & Pioneer 106 dvd-rom, esp burning at 4x write speed or faster.

anyone face the same issue ?
or should i just send for service ?

Sounds like a media issue.
What is the Media Code/Manufarturer ID on the discs you are using?

thanks for you fast reponse,

i am using burning mainly DVD+R,
so far, MMC seems to be giving the best result (exc disc bigger than 4.2G) on K-Probe on my system.
MMC disc also happen to be the cheapest here in Singapore(S$2.80 / US$1.60)
All the other brand cost ard 2x to 3x more.

Burned a couple of TY, result wasnt very good, PI-8 peak ard 150/200cnt (exc. spike)

i am suspecting the motor not performing up to standard…possible ??
disc-to-disc write quality varies even using same batch of disc with same write speed.

The 811 drives seem to be very variable as to quality of burns and like that. They batch test the drives then assign burn speeds and firmware depending on how they test out so some probably under perform some and some are just really good.
I have 2 and they aren’t consistent about burn quality at all, even with disk off the same spindle and different disks with the same media codes can vary wildly with them.
Mine seems to like Ritek g04- at 4x and Ricoh 01+ at 6x most of the time. Different firmwares can affect the burns quite a bit so try the 3 newest ones to see which one your drive likes with the media you have. I’ve been using HSOK with plus and I think E works better with minus.
