Hi Martijn,

the df command only shows the space(s) of those filesystems that are
currently mounted.  For any disks that have been recognised and are
accessible, you could try: #fdisk -l

For example, on my desktop machine it gives:
gsewell@desktop:~$ sudo fdisk -l

Disk /dev/sda: 40.0 GB, 40020664320 bytes
240 heads, 63 sectors/track, 5169 cylinders
Units = cylinders of 15120 * 512 = 7741440 bytes
Disk identifier: 0x000a326b

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1        5169    39077608+  83  Linux

Disk /dev/sdb: 40.0 GB, 40037760000 bytes
255 heads, 63 sectors/track, 4867 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x3f0a3f09

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1        4662    37447483+  83  Linux
/dev/sdb2            4663        4867     1646662+   5  Extended
/dev/sdb5            4663        4867     1646631   82  Linux swap /
Solaris

As you can see, both disks are 40GB.

Grant.
