Description Forrest 2003-01-09 20:28:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021127

Description of problem:
Using mediacheck to check the validity of discs (DVD) over 4 GB will not work. 
Their md5sums match, but mediacheck says that it FAILs.

Discs at 3.2 and 3.9 GB have been verified using mediacheck, but not over 4 GB.

Version-Release number of selected component (if applicable):
anaconda-8.0-4

How reproducible:
Always

Steps to Reproduce:
1.  Create a disc that is > 4 GB
2.  Use implantisomd5 to implant the md5
3.  Use the mediacheck boot flag to check the image.
    

Actual Results:  Mediacheck will say that the disc fails, even though it is a
good disc, and the real md5sums match.

Fixed in CVS:

It was stupid - a variable that should have been long long wasnt.

Here is the diff if you'd like to compile implantisomd5.c yourself (its all you
need to change):
