We recently had some failed the md5sum media checks on brand new media
from a vendor, upon cleaning the media and smacking the drive, they then
passed the md5sum media checks and we were able to install.

Of course we first tried it in multiple drives, and same issue, so I
guess something on the media's surface was the problem.
