During the last few days this site has had problems with a disk deciding to slowly die. Sorry for any inconvenience this has caused. Over this weekend (30th Nov...) it will be necessary to shutdown the server to install a second hard disk so that these problems do not occur again, this should only take about an hour.
Thanks, John
Update (3/12/07)
Its all done now and we have raid drives on the webserver so (fingers crossed) this problem should not happen again.
