Do you guys know why I'm getting such horrid burn results?
I got a BenQ DW1655 drive and I put it into a Vantec Nexstar2 enclosure. The ribbon cable and the power cable were connected but the audio wasn't because there were no pins on the BenQ. (I don't suspect that to be a problem though).
Using USB, I plugged the drive into my emachines-brand Model-M6809 laptop, which has a dead lite-on. The laptop runs on WinXP Home SP2.
The drive is immediately recognised.
I tested reading accuracy by using FC (in dos) to compare two 600MB files read from this DVD reader and a different computer. The reading seems fine because there are no errors reported by FC.
Then I used Nero 6 Express to burn 4.2GB of data onto a TDK-brand DVD+R at 8x speed. The TDKs don't give me errors on my LG drive on another computer. I turned on the Speed Test, Simulate, Write, and Verify options, and I turned off the multisession option. I kept on DVD high compatibility mode with automatic book type.
When I click burn, it says simulation is not possible for this disc, so it continues without the simulation.
After the speed test runs, it says that I can burn at 9x, and it continues to burn the preset 8x speed. At the end for burning, it says "Burn process completed successfully at 8x".
But then, when verification happens, it gives me stuff like:
"[...]Sectors from 15937 to 15953 on disc are different to source
Sectors from 15957 to 853399 on disc are different to source
Sectors from 853404 to 857645 on disc are different to source
Sectors from 857647 to 861784 on disc are different to source[...]"
And so on from the beginning to the end of the disc.
Nero says the burn failed of course.
I checked the burnt disc and it had the right file and directory structure, but when I used FC to compare files, the burnt files are different from source.
I tried burning at 4X with the same poor results.
I don't know how to see if overspeed or solidburn are on, but I don't know if that is important given that the burn doesn't suceed at 4x using TDK DVD+R.
The firmware on the benq drive is version BCDB
I also tried using the firewire connection, but the drive keeps disconnecting from the computer whenever performing heavy transfers. When it is connected, it says it is a Prolific device. At the same time, I have a firewire Harddisk plugged into my laptop, which works perfectly.
This sort of ruins my week because I'm a poor student. I've most tried things I can think of until I'm purple in the face :o
But I haven't tried testing the burner from another computer or removing the drive from the enclosure. Do you think it is worthwhile to test this?
Does anyone have and suggestions about what this may or may not be? I'm so upset I wouldn't even mind paying whoever solves this problem some money by paypal.
