I have a Lite-On 52246D with latest firmware.
I cannot seem to reliably write @ 48x or 52x. Kprobe reports a lot of C2 errors. I am using Verbatim 48x media which are Taiyo Yuden manufactured. These supposedly premium media.
The thing is my system is old. An Intel P3 700 on an Abit BX6 Rev 2 motherboard.
I’ve got two Seagate 80GB ST380021A ATA133 hard disks attached to an Aralion ATA100 UltraRAID 100 controller card. The CD writer is on the Abit motherboard which is ATA66 because the Aralion would not recognise the Lite-On no matter how I set the jumpers.
Now when I run Nero and do a speed test instead of an actual write it reports the max read speed as 36x
If I do an actual write @ say 48x it writes the disc fine but when it comes to reading back the media it gives C2 errors which are bad. Nero CD Speed’s scandisc also reports unreadable sectors on the media.
So the question is. What is causing the errors? The speed of data transfer from the motherboard to the writer? The speed of transfer from hard disks on the RAID controller? Or a combination of these? Why can I get a successful write but not a successful read of the media? Surely if Nero is cacheing and transferring the data fast enough to the media for a succesful write it should read back fine?
I can write at 32x and successfully read back the media which seems to correlate with it being under the 36x max read from the hard disks.
It’s annoying that I cannot even write to 48x the rated speed of this media. I have tried other media with similar results. I cannot just be poor quality media anymore.
