Hi, I am newbie to this forum, and I’ll tell you my problem:
I am regularly copying Verbatim DVD+RW 4x to Verbatim DVD+R 16x with Recordnow on-the-fly, and although everything runs fine, it takes about 30 min to write a 4.7 GB disc. It begins at 16x but after having 100 MB writen, it falls down to about 2x and ends, let’s say below 4x. However, if I copy the DVD to HDD and then to the H10N, it varies between 16x, 10x, 12x.
So, I began to think that the problem is on the IDE bus. I have only one, with the LG H10N as master, a Liteon XJ-HD166 dvd reader as slave, the rest are WD 160 GB disks on SATA, two of them on RAID1. The processor is a Dell Dimension 8400, P4 3.2 Ghz, 3 GB ram. WinXP Home SP2 to the last update.
And Nero CD/DVD Speed gave me some reason as the reader and the writer, each one alone, took more than 50% of cpu utilization at its higher speeds.
I use 80-wire cable, but the Device Manager shows UDMA2 for both devices, that could be the reason for high utilization and low speed. Specifications for the Liteon reader says it is only UDMA2 capable, but I have seen in this forum that I should force H10N to UDMA4 by flashing some firmware from TDB.
There. at TDB site, I have seen three possible firmwares: JL11 and JJ11 for H10N, and UJ12 for H12N, that could be valid too. But I have also read about people that had problems with those fw and were not able to go back. By the way, my firmwares are the latest from Liteon (DD06) and LG (JL12).
I have also thought that riplock in the dvd reader could be part of the problem, but I don’t know if its possible to avoid it.
So, questions are: 1) Any other possible reasons for this performance? riplock? 2) Should I risk my writer box by trying those TDB firmwares? 3) Which of them, if it doesn’t matter too much 16x or 18x?, and 4) Any solution if I would decide to come back to the JL12 LG firmware?
Thanks in advance
