As alluded to elsewhere, my computer has given up the ghost. While there are many worse things that could have happened the morning after exchanging contracts on the house move, turning my machine on to see the message
Drive Read Error
Press ctrl-alt-del to retry
did not fill me with joy. Since it still complains about drive errors
even with the drives taken out I'm pretty sure this is (a) a motherboard fault and (b) a terminal one. Hopefully it hasn't trashed the actual drives on the way out, especially since my backups are (oops) several months old. None of the data on them is actually valuable, but losing/having to redownload it would be irritating.
Also, of course, moving house involves a lot of communicating with people, and while my spare Raspberry Pi is ferpectly adequate for text emails, it's not the best machine in the world for dealing with people's websites (and doesn't have my comprehensive collection of relevant bookmarks and stored passwords). Again, hardly the end of the world, but adding nuisance factor to something that's already stressful and time-consuming.
And because of the short notice, we're going to be without phone and internet connections for the first week or so after we move. Which might make it easier to get more than just our computers unpacked, now I think about it, so maybe that's not all bad :)
