should have option to verify disc content without burning

[mlg7]

Binary package hint: k3b

2 use cases:

1.
k3b failed on laptop when burning DVD.
It ejected the DVD and could not get it back.
Burning has completed, but verification failed.

2.
I could just forget to check the verify box.

In both cases, I want to verify the disk without writing data.

Sometimes I forget to check verify written data before burning. K3B could need a function to verify a burned disk afterwards.

[Jospoortvliet (jospoortvliet)]

this whould be really nice. I vote for it.

I also like this idea

While we're at proposing improvements for verifying I suggest speeding it up somehow. Here k3b takes ~25 mins to verify a disk while diffing the files takes ~3.5 mins...

[Jospoortvliet (jospoortvliet)]

k3b computes a md5sum for both files, then compares them. md5sum is quite slow, indeed diffing might be faster...

Just to clarify, you want a redo of the md5 sums later on, as opposed to some quick way on inserting a cd and checking if this is the cd that was burned from this project (This is different, because the file content might have changed in the meantime and no md5 can be calculated)

[Helge Hielscher (hhielscher)]

Ideally it would display the different files as requested in
Bug 77310: verification: mark different files in the project view

[Christoph Burger-Scheidlin (andersin)]

If that is the ideal solution, is it ok to close this one as a duplicate of bug 77310?

[Helge Hielscher (hhielscher)]

no this bug is about verifying after burning, bug 77310 is about how to display the result of verification in general
