BD-RE & 45.1GB

[Rusty_Shackleford]

Hi All,

 

First of all, if this has been mentioned previously, I apologize, mods feel free to close thread.

 

I'm quite new to burning blu-ray iso's onto BD-RE's, although I know enough on how to burn them, my question is what the Topic suggests. After burning a ISO to the BD-RE disc and I complete an erase (whether it be a imgburn quick or full erase, even both) I found that the disc isn't displaying a total of 50GBs. Now, I'm not sure if it said 50GB from the start, but I was under the impression, you purchase a 50GB BD-RE, you get 50GBs. Now if I attempt to burn an ISO that is bigger than 46GB it will not burn because the disc doesn't have enough space. If this helps, the disc is a TDK.

Something similar has happened with the single-layer BD-RE I have. Rather than this displaying 25GB it displays 22.5GB.

I didn't notice if the disc displayed 50GBs of free space before the initial burn.

Is this how related to the whole Binary Base 2 notation of how data is stored on discs?

 

Any help will be greatly appreciated.

Thanks in Advanced!

Yes, it's a from dividing by 1024 instead of 1000.

 

You haven't lost anything.

 

Formatting without spare areas will give you the max available capacity.
