Red Hat Bugzilla – Bug 869817
brasero silently ignores I/O errors reading .iso file
Last modified: 2017-09-14 08:05:34 EDT
Description of problem:
Brasero ignores read errors when burning a DVD from a .iso file.
The user thinks a fine DVD has been burnt, but that is not the case.
Version-Release number of selected component (if applicable):
You need to have a .iso file with a bad hard drive sector (sadly, I do).
I've been able to reproduce it several times (inadvertently -- quite a waste of DVDs and time).
Steps to Reproduce:
1.You need to have a .iso file with a bad hard drive sector (sadly, I do).
2.Try to burn that file with brasero.
3.If nothing else goes wrong, brasero will say: "Image successfully burnt to CD" (even though it is a DVD).
brasero says that it succeeded.
dmesg says that there were hard disk drive errors. smartctl and dd too.
brasero says: I/O error in .iso file; burning aborted.
Knowing about I/O failures is critical. Hiding them from the user is a big mistake.
The .iso with a problem was Fedora-17-x86_64-DVD.iso. I detected the problem when installation failed (but the symptom did not clearly point at the problem).
Since getting I/O error for testing purposes is hard, I would consider NOT fixing my hard drive for a modest amount of time to facilitate testing of any proposed brasero fix. Let me know ASAP if this is useful.
