Can't mount my SATA drive

[Duncan Lithgow]

Hi all,

Running Breezy - up to date. Freshly installed (yet again!). I have an
ATA HDD with most of my stuff on, recently I installed a SATA drive, and
after a bit of fiddling in BIOS ubuntu saw it and all was good. But now
after reinstalling Ubuntu - it's gone! gparted can't see it either.

Device manager can see it:

> 82801EB (ICH5) Serial ATA 150 Storage Controller
	SCSI Host Adapter
	SCSI Host Adapter

I've added a few things into fstab, hoping it would help - it hasn't.
# SATA drive(s) (sda)
/dev/sda1	/media/sda1	ext3	defaults	0	0
/dev/sda2	/media/sda2	ext3	defaults	0	0
/dev/sda3	/media/sda2	ext3	defaults	0	0
/dev/sda4	/media/sda3	ext3	defaults	0	0
/dev/sdb1	/media/sdb1	ext3	defaults	0	0
/dev/sdb2	/media/sdb2	ext3	defaults	0	0
/dev/sdb3	/media/sdb3	ext3	defaults	0	0
/dev/sdb4	/media/sdb4	ext3	defaults	0	0

When I run mount all I get
$ sudo mount -a
mount: special device /dev/sda1 does not exist
mount: special device /dev/sda2 does not exist
mount: special device /dev/sda3 does not exist
mount: special device /dev/sda4 does not exist
mount: special device /dev/sdb1 does not exist
mount: special device /dev/sdb2 does not exist
mount: special device /dev/sdb3 does not exist
mount: special device /dev/sdb4 does not exist

So, what am I getting wrong - it was working the other day.
