The values in /proc/partitions are larger than df values on all three
of my Linux systems, 1 FC7 and 2 FC8, one of which I just installed
to fix the problem box. Here are two additional points:
1. When installing on the problem box, the installation software
informed me that it could not read a track; I don't remember
what it was, but it sounded related. For unrelated reasons,
I redid that installation. On the second try, there was no
such report. I note also that before these installs, I ran
memtest86 and fsck, and found no problem.
2. Remember that the problem box has 125M ram, 20G disk, 400 MHZ.
Furthermore, in some recent operations, I filled the disk to
about 85%. At least in my case, no other hard drive is filled
that full. I wonder if this is part of the problem.
