PI/PO errors with 851s?

CD, DVD and (Ultra HD) Blu-ray Writers LiteOn / PLDS / Sony Writer
#1

I just got a new 851s. Updated to latest firmware and I burned my first disc at 4x, lite-on smartburn identified it as ricohjpn.

nero cd/dvd speed seemed to read the disc just fine. Then I put the disc in my lite-on LTD-163D dvd drive (GHR8 firmware) to use with kprobe 1.29
here are my results with PI/PO sum :1

everything looks great, but when I was reading the review for the 811s here I noticed the article used PI/PO sum :8, so I tried that

and the PI errors shot up quite a bit. I haven’t had a cahnce to run kprobe with the dvd burner as the reader yet (trying not to reboot that machine for a while) but are these results normal?

Try rescanning your disk in your DVD burner. The DVD ROM drives are know for higher graphs.

#3

What media did u use??

Is your latest firmware “GS0C”??

#4

media is code ricohjpn 4x rated, burned at 4x. The burner had the firmware “GS0C” before burning.

So I finally got around to getting k-probe on my burning machine, and doing a test, the relsults are weird:

I’ll probably burn a few more discs to see if I can get a more normal graph.

edit:
Just did the test at 4x (instead of 8x read) relsults are much better

so if I wanted to copy a burned dvd, should I limit the read speed then?

#5

The 4x scan looks pretty ok… actually better than mine with GS0C…

how can u limit the read speed?? I mean, Neo drive-speed doesn’t work for me!! Just make sure u make an image on the harddisk 1st :wink: They should give u an error if the program cannot read the source.

I haven’t done anything with it yet, but nero 6 has a tool called nero drivespeed, which seems to let you set maximum read speeds

edit:
I realized you probably meant nero not neo in your post…

mehmehmeh, Your scans look pretty much the way mine do with that firmware. They’re “OK”. but I lite-on improves on these write stratagies because this type of burning isn’t very good… .Oh well… I heard GS0F just came out. I’m going to upgrade to that with hopes of better burning. Good luck with your new burner.

#8

Those scans are much better than the 811S that I have… Id be happy if I were you, because it looks like its burning pretty well…

#9

Forgot to mention, you may want to scan @ 2 or 3X because this drive is a bit flacky when scanning at 4X. Go figure?.

#10

His drive seems to scan OK @4X.
My 411@811 scans like crap @4X, that’s why I do scan @Max usually. Of course I do use also 8ECC.
