Device Buffer Problem - BD-RE

[facls]

Hi,

 

I've been using IMGBurn to burn BD-REs for some time, writing the BDMV and CERTIFICATE folders.

 

FOr the past few weeks, burning them has become very, very slow, though it still burns successfully. The Device Buffer keeps dropping from 100% to 40% or lower, then slowly goes higher, then drops again. Burning the discs, which usually took some 15 minutes, more or less, now takes three times as long.

 

I don't know what it could be, since I made no changes in the way I burn them, from where I burn them, or made any changes to hardware or firmware.

 

On the log, there is a warning: SPTD can have a detrimental effect on drive performance. Is this related? If so, how can I solve this? I'm using IMGBurn 2.5.0.0.

 

Thanks in advance.

 

Fabio

It's weird that the log doesn't show any errors (like "Waiting for buffers to recover") but it does take an awful long time to burn. Maybe it's the media. I notice you're using the LG BD-RE disc. I got the same disc with my LG drive and couldn't even format it. I've since read that they're terrible discs. Maybe the disc, even though it worked before, has had it. Can you try another disc?

You've formatted that with spare areas enabled so the drive will be verifying ever sector it burns as it goes along.

 

You shouldn't expect to see anything more than about 1x when that happens.

 

Of course 1x is what you get on a decent disc! If the drive has to write and rewrite (and possibly relocate) sectors, it could take loads longer.

 

So I'd say to give better discs (Verbatim) a go.

 

I'd be interested to see the IBG ('Graph Data File' in the log) from that burn too.

Thank you all for your help, tonight I'll try with a new BD-RE (I have an unopened from Sony). This LG disc, which came with my drive, is also new, I've had it for 6 months. The burns are slow but they still work on my Blu-ray player.

 

Can I format with spare areas disabled? I mean, 2h30 to burn when it took me 15 minutes is just ridiculous.

 

I've attached the IBG.

The default options in ImgBurn (i.e. after a clean install) and a full format will format the disc without spare areas.

 

The IBG is too much of a mess to get anything useful from it. Oh well, worth a try!

[facls]

just tried the full format option, after 1h21m, error at the very end:

After that, tried the quick format option, it was successful. I'll now try to burn the project again to see if it has changed.

It's working! Apparently formatting it did the job. I burned it quickly and successfully. Then I tried quick format, burned another BD-RE and it worked again!

 

Thank you all for your help!
