LTR-52246s, V6S07 firmware shows PCAV!!!

[hrbngr]

I have searched the forum for info on this firmware,but the V6S07 firmware loaded on the LTR-52246 that I just purchased (Cendyne Lightning V) shows type P-CAV when I create a data CD.

according to Nero CD SPeed, the starting and end speed is approx. 24x and the average is 31.49x, total elapsed time is 3:12 for disc creation.

can anyone confirm?

I checked the info on the latest firmware V6S0C and the images in the topic showed CAV...wonder why they would go back to CAV...

any ideas?

i am unsure how to link a pic to this site, so here is the address where the pic can be viewed:

sorry for the hideous site...i will be getting the hang of it shortly!

That's SMART-Burn in action. It monitors the writing process and if it detects that there are problems with the media you're using, it will slow the recording speed down.

Ian, can you be more specific?

as opposed to the CAV writing style here:

it is using P-CAV which is faster, right?

I thought that ppl were looking for a firmware upgrade that used P-CAV on the Lite-On LTR-52246.

People are looking for a 24x P-CAV RW not CD-R. I think what you are talking about is CD-R because you got an average of 31.49x.

ok,

understand about the 24x P-CAV cd-rw from the previous post.

Here is my question. I purchased two identical LTR-52246 drives with V6S07 firmware. (one serial number 201247004452-PCAV and other 201247004347)

I tested them on the same machine w/a minimal win2000 install and nero 5.5.10.0.

when making a data disk with CD speed, one drive uses P-CAV and one drive uses CAV, never changing...I wish I knew why.

I would really like to figure it out before I flash the firmware to V6S0C firmware--as if I go back to V6S07, it might go back to using CAV only...

does it really matter?

Did you use the same disc?

Like I said in my post above, thats Smart-Burn in action. If the drive wouldn't have slowed the writing speed, it would have used CAV.

so if SmartBurn is enable for both Lite-Ons and one does the Data Disk on CD Speed at a slower speed with the same media-TY, does that indicate that there is a problem with the driver that is burning the TY media? the Lite-Ons are the same model and have the same firmware--almost the same serial number.

First, I am going to upgrade the firmware on the unit that burns the TY media slower (P-CAV) to S0C and verify if this makes a difference. also, I will use CD Doctor to view the C1 errors generated while creating the data disks on various media with both firmware versions to see if there is a problem.

Next, I will buy another identical CD-ROM and check to see if it also has problems burning TY media..aren't Lite-Ons supposed to be good w/Taiyo Yuden?

If the 3rd unit burns the TY properly--even with the older firmware, it might be best just to go ahead and return the "defective" unit I guess...

any thoughts?
