Comment 15 for bug 1548120

@hakuna_matata -- thanks for the report there, testing here confirms your findings that they are upper case on NTFS and only match with upper case. Properly the fix for this whole mess should be in util-linux in blkid as the individual formats have specific forms and only it knows what is appropriate to do to that UUID such that we do not lose information in the transformation. I am filing a new bug for that isssue so we track it clearly. See Bug #1553107.
