Brasero - recognises a 4.7 gb writable dvd as 4.3 gb

[asifanwar98]

Binary package hint: brasero

See attached screen print it shows Brasero not having any option for a 4.7 gb dvd. I presume there is a config file some were which lists standard cd and dvd sizes (not sure where though ?).

Thanks for your report, could you run brasero from the command line as: brasero --debug &> brasero-debug.txt perform the operation to reproduce the bug and attach the resulting file to the report?. Thanks in advance

This is not a bug, it is just that the DVD makers describe their disc capacity using GB = 1000^3, but brasero is reporting the capacity using GB = 1024^3. See http://en.wikipedia.org/wiki/DVD-R#Recordable_DVD_capacity_comparison.

@Mike:
If it used GB as in 1000^3, it would say "4.7 GB". The 4.3 are referring to GiB (4.7 GB ~= 4.3 GiB).

This is definitly a bug, since it uses wrong units.
See
    man 7 units
for more information.

Thus, I dare to reopen.

This is fixed in Ubuntu 10.04 (lucid) with the upload of glib2.0 2.23.5-1ubuntu2, which follows https://wiki.ubuntu.com/UnitsPolicy

Are you sure? According to this, it's still showing a 700 MiB CD as "700 MB":

The attached screenshot shows two numbers: The ISO is 707.1 MB. When you burn the CD, 29.8 MB will be left. I summary, you can put 736.9 MB (~ 700 MiB) on the CD.

[Endolith (endolith)]

You're right. I misunderstood the complaint.

[Benjamin Drung (bdrung)]

With glib2.0 2.23.5-1ubuntu3 we are back at the previous state.

Not sure if its the same bug but seems related:

When I open Brasero with an empty disk inserted already, click on Burn ISO Image, it shows me that there is an blank DVD with 4.3 Gb free inserted (though its 4.7 by manufacturer definition). Yet after choosing an ISO to burn (4.7 Gb), Brasero changes the information shown to "4.0 Gb free space". Somewhere between real free space and calculated free space after selecting ISO it gets lost.
I also cant burn any DVD where this happens. Brasero starts the process and gets stuck in "preparing to write" forever.
