How to find out the exact number of Bytes which fit on the current media (CD/DVD)?

Recommended Posts

Is there a way to find out how many bytes fit exactly on the currently inserted media?

I mean not by investigate it somewhere in Internet/Wikipedia but by clicking a menu in ImgBurn?

It's in the box on the right when you're in Write mode.

 

 

Hmm, that is the official but NOT the real size!

 

Lets say I have a DVD+RW which has an official capacity of 4700372992 bytes.

That is what is displayed in ImgBurn info box.

 

Ok, now I switch to "Build" mode and dragged 10 (big) archive files onto the ImgBurn window.

The total sum of all these 10 files is 4700312452 bytes.

So it should fit on the DVD+RW and I started the burn process.

But then ImgBurn stops and warns me that the media capacity is too small for burning all the stuff.

 

I guess ImgBurn needs some extra amount of bytes to burn the management info data onto the DVD media as well.

But how much is this (e.g. for MODE1/2048 ISO9660 + Joliet)?

 

Can ImgBurn display this REALLY AVAILABLE capacity as well?

 

The warning tells me something about 2.295.104 Sectors. How much ist this in bytes?

It's impossible to say that there's exactly X amount of space (bytes) available for file data.

 

You have to take into account the number of files, the file system selection and various other options.

 

The actual amount of free space on the disc is shown in the box on the right.

 

For DVD+RW / BD-RE, it would be the 'sectors' / 'size' (capacity) of the disc because they're never empty once formatted. For everything else it should be shown as 'free sectors' / 'free space'.

 

Disc Information:

Status: Complete

State of Last Session: Complete

Erasable: Yes

Formatted: Yes

Sessions: 1

Sectors: 2,295,104

Size: 4,700,372,992 bytes

Time: 510:03:29 (MM:SS:FF)

MID: MKM-A03-00

Supported Write Speeds: 6x, 8x

 

Disc Information:

Status: Empty

State of Last Session: Empty

Erasable: No

Free Sectors: 4,267,040

Free Space: 8,738,897,920 bytes

Free Time: 948:15:65 (MM:SS:FF)

Next Writable Address: 0

MID: RICOHJPN-D01-67

Supported Write Speeds: 4x, 6x, 8x

 

The 'Calculate' feature is there to work out *exactly* how much space is required for your project based on the current settings.

The "Free space" value seems to be available only for "write" mode but NOT for "build" mode.

Or did I miss something? I do not see "Free space" at least in the "Device" tab in "build" mode.

You missed something.

 

To quote myself again...
