Linux doesn't show other physical hard disk?

[oscar2043]

You must read about commands like mount in order to understand linux file system.

A short introduction
create a folder anywhere but usually is a folder in /mnt
for ex. /mnt/mywin

then run the command
mount -t vfat /dev/hda1 /mnt/mywin

vfat is fat32
/dev/hda1 is the first partition of first master disk

then double click on /mnt/mywin and you are into c:\

Try linuxconf to configure anything including hd and cdrom.
