Red Hat Bugzilla – Bug 455876
sr# 1798266 : kde/K3B Verify data says it differs, but it does not (rounded up to 32KB)
Last modified: 2014-01-12 19:07:35 EST
Description of problem:
When burning a DVD image, k3b claimed the written data
would differ. This is very irritating for users (adding more confusion
to the unreliable CD and DVD burning process).
The written data does not differ, but K3B seems to
write in 32KB blocks; when the ISO image is not
on a 32KB boundary it is filled up with NULLs.
Technicalls the Image is different, but K3B should
take this into account and not complain.
Steps to Reproduce:
Write a dvd image, as one from -
$ ls -sk SUN_Ultra24_Supplemental_1.1_Bios_1.10_tools_and_drivers.iso
k3b complains that md5sum has failed
md5sum is correct, as shown in RHEL5.

suspected fixes -
This appears to be a bug that occurs on x86_64 systems. I couldn't reproduce the
bug on x86 and since I haven't got a DVD burner on my x86_64 box I haven't got
any way of checking to see if the patch has introduced any regressions.
It doesn't seem to have any impact on my x86 system so I'll pass the patch up to

Patch reviewed and works.
