Verbatim Ultra Speed CD-RW write quality question
Posted: Sun Apr 06, 2003 4:37 am
I have a TDK VeloCD 52/24/48 CD-RW drive--I know this is a rebadged LiteOn LTR-52246S with the TDK bezel and read speed reduced to 48X. Also, the drive uses TDK firmware (no doubt written by LiteOn). I am using firmware version 67U4. I have CD Doctor version 1.0.4. My burn quality with Verbatim DataLifePlus 16X-24X 74 min Ultra Speed CD-RW discs seems to be inconsistent with that of the other LiteOn drives posted in this forum. For example, I can't get the burn quality listed at the topic at the URL:

I'm in a hurry, so I don't want to post images here. I have gotten a few burns to this media that have quality that seems to be unusually poor (compared to the above URL and other similar postings) for this media. For example, one burn I did was to a disc that was never written to, but was full erased once. The error info for that disc is:
C1: Min: 0 Max: 183 Ave: 28.747
C2: Min: 0 Max: 0 Ave: 0.000
This was written @24X, and read at max speed in CD Doctor. The issue here *appears* to be the TDK firmware and the difference between the LiteOn LTR-48246S and the LTR-52246S(my TDK). My understanding is that there shouldn't be any real difference in write quality between the LiteOn LTR-48246S and the LTR-52246S since they both use the same series 6 chipset. So, I perceive my problem to be with the TDK firmware. Will I get my C1 average down to something close to the 2.723 with Max of 14 that MediumRare posted if I switch to the latest LiteOn firmware? What is causing such high error rates? These discs are *not* the Memorex Ultra Speed discs! My CD-R write quality is great, so that is not the issue--I am able to get a 0.1 C1 average on TY media.
