Since you're probably running correllinux check under "Control Center"
under "Hardware" under "Drives" under "Hard Disk" what kind of devices
are present. e.g. /dev/hda or /dev/hdc etc.
run "fdisk" use option "p" to print info about the disk. Here you can
analyze the partitioning of the disk. You will probably find something
in /dev/hda1 and /dev/hda5.
Create a test directory under /mnt/local/test
mount /dev/hda5 /mnt/local/test
This should work.
You may want to read the manual pages for "fdisk" and "mount" to check
about the several options and info which is given.
Success.
