Paraphrasing Ben Fennema thoughts of 2004-05-24:
Somebody please make a disc, write a file of more than
2 GiB on to it without holes, confirm that the phgfsck
likes it, and then confirm or deny that Linux udf.ko
represents its length correctly.
We really should find we can do all of this in Linux,
done, but if need be we hear the dd of Mac OS X and the
pldd of Windows can do it. Key is acquiring a dd that
copes with lengths above the signed 32-bit limit of
x7FFF:FFFF B = 2 GiB - 1.
Higher priority because Ben's interested, gave us much
or most of udf.ko, and is now maintaining udf.ko.
Lower priority because as yet we have not reproduced
