Issues With Blu-ray Drives?

Postby Ian on Sat Jul 29, 2006 12:08 am

I know that Nero 7 supposedly supports Blu-ray drives but when I write to BD-RE media with my Pioneer BDR-101A, the drive writes at about 0.5x. The Roxio software that comes with the drive works fine. Has anyone else run into similar problems?

I run into problems using Nero 7 all the time. It doesn't take BluRay media for Nero 7 to suck :wink:
Punch Cards -> Paper Tape -> Tape Drive -> 8" Floppy Diskette -> 5 1/4" Floppy Diskette -> 3 1/2" "Flippy" Diskette -> CD-R -> DVD±R -> BD-R

Hi Ian,

Have you tested with our latest release of Nero 7 on our website currenlty?

There was an issue with the Pioneer drives that caused 25gig of data to take 2 hours or more to burn, instead of the expected 45min.

After performing several tests it seems the long write time is not dependent on the used Set Stremaing command where the write speed is set, but it depends if the spare area is allocated before writing or not.

For the Pioneer the Set Streaming command is not send as the drive reports only one write speed for the loaded BD (2x). Even to force set the write speed does not change the writing time.

In comparation with other BD drives the Pioneer needs some more time for writing in case the is formatted with a spare area. Maybe it does some read-after-write action in order to check if the written block was ok.

Nero uses per default the allocation of a spare area as this is the default format mode and has the maximum reliability of the written data on BD-R/RE. The alocation of a spare area allows the BD drive to replace bad
blocks on the media with blocks from the spare area.
Not using the spare area may result in unrecoverable write errors and the termination of the write process.

In order to solve this issue I propose following:

(temporary solution) Make an exception for the Pioneer BD drive and do not format BD discs per default with a spare area.

We are working with Pioneer to properly address this issue in future builds.

Regards,

Craig

I think it applies to more than just Pioneer's drive. I haven't tried it with the latest version but I was able to get it to work by disabling the spare area stuff in the registry.
