fstab entries show non-linear partition numbers

Code:

/dev/hdb6 / ext3 defaults 1 1
/dev/hdb1 /boot ext3 defaults 1 2
none /dev/pts devpts mode=0620 0 0
/dev/hdb10 /home ext3 defaults 1 2
//mage/STUFF /mnt/STUFF smbfs user,suid,username=% 0 0
/dev/scd0 /mnt/cdrom iso9660 user,ro,exec 0 0
/dev/scd1 /mnt/cdrom2 iso9660 user,ro,exec 0 0
/dev/fd0 /mnt/floppy user,suid defaults
/dev/hda1 /mnt/win_c vfat iocharset=iso8859-15,codepage=850,umask=0 0 0
/dev/hda5 /mnt/win_d vfat iocharset=iso8859-15,codepage=850,umask=0 0 0
/dev/hda6 /mnt/win_e vfat iocharset=iso8859-15,codepage=850,umask=0 0 0
none /proc proc defaults 0 0
/dev/hdb9 /tmp ext3 defaults 1 2
/dev/hdb7 /usr ext3 defaults 1 2
/dev/hdb8 /var ext3 defaults 1 2
/dev/hdb5 swap swap defaults 0 0

Is there an obvious reason that hda2-4 and hdb2-4 are missing ?
All partitions are in use - there's no free space.

Yes there is. Primary partitions are numbered 1 through 4. Logical partitions are numbered 5 upwards.

Basically, your disks have one primary partition (i.e. hda1), and a bunch of logical ones.

No worries. It is normal and just the way the partitions were created.
In a nutshell
Primary partitions are 1-4
logical partitions are any partitions >=5
An extended partition is a container for logical partitions. This is the method to create more then 4 partitions.

To see how the drive is partitions log in as root and type in the command.
/sbin/fdisk -l /dev/hdb

I would guess that your extended partition is hdb2 which is not mounted and not shown in the fstab file.
