Dear Paul,

the subj still has its place (with the same descriptions) at 3
different NEC 5800 computers at my office (all are with large 250Gb
HDDs formatted as one ext2 partition) - and one with just freshly
reformatted, reinstalled and fsck'ed system. I believe that the subj
is NOT about the OS or FS. And other programs (exclude df) are
detected the space correctly. Anyway, I've just reporting you the bug,
and you decide what to do abt it, bcause I've no idea what to do - df
was an easiest way to me to check the free HDD space available, and
now it's been failing. :\

See below (the large disk is /dev/hdc everywhere below):
