I bought a 48246K LiteOn a few months ago and I'm very happy with its performance when writing CDRs - very consistent results - and its great range of features.
Problem is it seems very inconsistent when writing CDRW's.
Due to LiteOns annoying choice of making 24x CDRW burning full CAV instead of the much quicker P-CAV enjoyed by nearly all of its competitors, I burn CDRW at 16x CLV as it's faster 90% of the time.
Some days it'll give results of 30 C1 errors, others it'll touch on 1000 and yet others it will produce C2's.
Now after experimenting I just can't come to ANY conclusions. I've written to the same disk repeatedly, used different disks and still can't get any consistent results. Just when I think I've nailed a theory, another result jpops up to throw it to hell!
For instance, when I first got these verbatim 24x CDRW I carried out these tests , very repeatable ON THE DAY.
Now the same disks (and brand new ones) went and gave C1 results in the 1000's. Then after a computer reset they dropped to C1's in the 400's, later back to 30's then upto 200 again ARRRGH!!!!!!!
After doing multiple tests it seems that for some reason the Liteon drive isnâ€™t calibrating the laser and write strategy correctly (or at least differently on certain burns) and producing strange results. The media will be consistent one moment, then be all over the place the next, then go back to normal again.
Now these disks are still readable but I'm trying to understand why the CDRW tests vary so much as I'm getting C2/slowdowns from time to time when verifying data. It doesn't matter if the disks are used, new or extreamly battered, the drive decides to cause high or low c1's/c2's on a given boot!
When I used to write CLV 4x CDRW's on my trusty mitsumi, the results were extremely consistent and repeatable, not like this CLV 16x RW business!
BTW I'm already using the latest firmware.
