25GB Blank Bluray Question [SOLVED]

[dwsiddall]

Using BurnAware software I filled up a 25GB disk with files (see Photo #1).

After burning AND verifying, I look at the disk and to my experience with disk burning (25+ years)....it looks like it only actually filled half the disk (see Photo #2).

So my first thought was, Ok...this must be a 50GB blank Disk. But I know I didn't buy 50GB disks because they were so much more expensive. So then I thought, well maybe they sent me 50GB disks by mistake, But when I set the disk size in the software to 50GB, it errors out.

Any thoughts appreciated.

Inserted a blank disk and used different software to verify....it is, indeed, a 25GB blank disk. I've burned it twice and got the same result (looks half-full).

Verified this further by looking at some disks from the same batch that I burned some months ago and they look correct (dark/burned area covered entire disk).

The color may depend on the burning speed. If the speed was set to auto it can use different burning speed for different areas.

1-2gb approx each. They are movies.

Did your burning software's logs report any errors? Can you play all of the files that you intended to burn from these BD-Rs without any issues?

I know this back in the day called coasters, Do a file integrity check, if all files are there why does it matters how it looks?

Read post 3 for the answer.

Even post 3 answer is nebulous because we don't know the burning speed that the original poster used.

[johns0]

It isn't nebulous,the op wanted to know what caused the difference in burn pattern and was told it was difference in burn speeds and he was happy with the explanation.

Exactly correct. Thank you for stating what needed to be stated.

Surely you don't really think the issue was just being unhappy with "how it looked", right? The question was seeking info on why it APPEARED to only be half-written. The answer, as it turns out, was that INDEED it only LOOKED half-written. It was fully written across the entire span of the disk, it just had a lighter color due to the software using different write speeds on different parts of the disk.
