device don't show up in df

I have installed Ubuntu 7.10 from CD on a SATA-drive:
Everthing seemed OK until I looked at the drive with GParted which complained about missing mountpoint (see attachment).

fdisk -l gives:

Device Boot Start End Blocks Id System
/dev/sda1 * 1 60424 485355748+ 83 Linux
/dev/sda2 60425 60801 3028252+ 5 Extended
/dev/sda5 60425 60801 3028221 82 Linux swap / Solaris

/etc/fstab gives:

# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda1

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0

but ...

df -h gives:

Filesystem Size Used Avail Use% Mounted on
varrun 505M 240K 505M 1% /var/run
varlock 505M 0 505M 0% /var/lock

devshm 505M 0 505M 0% /dev/shm
lrm 505M 34M 471M 7% /lib/modules/2.6.22-14-generic/volatile


Where is /dev/sda1 in df listing

Someting is very wrong but I can't figure out how to correct it ...
