So my week goes something like this:
Sunday night - work on a lab for 4 hours.
Monday morning - hard drive dies, work lost
Wednesday - finally get hard drive replacement, spend the day looking for and trying to use various downloaded versions of windows, with little help. finally get one working and spend the entire night reformatting my computer.

Also, an interesting note. if your hard drive dies of mechanical failure, there is one possible way to reclaim data. By putting it in the freezer, it is possibly that the contractions resultant in the metal parts will cause some broken joints to be reconnected, small parts to be moved back in place, ect. But you only have a good 10 minutes before it warms up and dies again, so make it count.
I liken it to reviving a dead person long enough to ask them one question.
