[ubuntu-uk] Fsck for bad blocks?

[LeeGroups]

I'm having an issue with my new Viglen mini PC which I've just set up as 
my latest home server.
I've been copying stuff to it over the lan, but it was failing, so I did 
an fsck -c to check for bad blocks.
The output is below...

lee at mserver:~$ fsck -f -c /dev/sda1
fsck 1.38 (30-Jun-2005)
e2fsck 1.38 (30-Jun-2005)

/dev/sda1: 11/1311552 files (0.0% non-contiguous), 73973/2622603 blocks
lee at mserver:~$

The question is - were there any bad blocks?
The filesystem was modified and the number 603 looks ominous, but it 
doesn't say any bad blocks were found...
