Tom proposed the following answer:
Well sdb1 is a bit of a mystery to me too.  I've been assuming it's some
kind of special "restore to factory defaults" type partition - well
worth leaving alone in case you ever want to send the machine back to
the shop for repairs or something (although 20Gb seems unusually large
for that).  I think the error message might be something to do with
having to define non-normal linux file-systems when doing the fsck check
but you can see i'm struggling for an excuse there.

What i find truly strange is that linux is on your first main primary
partition on your main drive!  Even more amazing is that Windows is
relegated to a Logical partition inside an extended partition!  I have
to say this is great to see as it suggests that Ubuntu was pre-installed
& Windows added later and the partition for Windows appears to have been
created by a Windows Partitioner rofls :) However, it does still give us
a bit of room for manoeuvre :)

Firstly is to get to grips with how to use fsck so get to a terminal
console and type in

fsck -h

if that gives tooo much info then try adding a " | grep more" to make it
pause when you get to the end of a terminal-full and wait fo you to
press the "Space Bar" on your keyboard before printing more.  So try

fsck -h | more

and lets see how to run a decent check of all your partitions and
perhaps fix errors as it goes along.  Ntfs is also journalised
(similarly to ext3) so it's not likely to be seriously damaged, with any
luck.

Good luck and regards from
Tom :)
