It's all right there: df says you have about 8G in them there partitions.
This may be a case of running into the 8GB limit, one of many breakwaters
above the 512MB line where the traditional BIOS and IDE controller
addressing fields don't have enough bits in common to directly address all
the blocks. 8GB is usually the size all drives larger than that size report
to the BIOS, but Linux is usually capable of seeing the drive's real size.
So perhaps you're hitting a side effect of the 32GB truncation - 80 modulo
32 isn't quite 8, but then the count isn't in binary KB anyway, so that
could be it.
OTOH, you just might have one of those self-consuming disk drives. taht
would be very bad, and you wouldn't want to have it in the system with any
other drives; after it has consumed all of its own free space, it will start
in on any other drives in the system. Perhaps it would be best if you sent
it to me for investigation and safe disposal, eh? :-)
