[NTLUG:Discuss] K3b question

[Fred James]

I have never seen this one before and I would appreciate any clues ...
Downloaded some iso files (some CD and some DVD) ... all of them check 
out OK for sums (both md5 and sha1)
But one file (619.0 MB) always fails the write verification ... the 
others pass.
I even downloaded the suspect file a second time ... it too passed the 
sums, but failed the write verification

One of the files that passes verification is 692.0 MB, so it can't be 
size ... anyway it is a 700 MB CD-R disk
Thank you
Regards
Fred James
