>Description:
A cdrom given to me by a colleague has it's size reported incorrectly
by 'df -k'.

# pwd
/cdrom
# du -ks .
662549  .
# df -k .
Filesystem  1K-blocks     Used     Avail Capacity  Mounted on
/dev/cd0a      297814   297814         0   100%    /cdrom

I am yet to determine what is "wrong" with the file system for this to
occur.
>How-To-Repeat:
Mount strange cd9660 file system, observe difference between df and du
output.

I will investigate further on other systems and report the results.
>Fix:
Unknown.
