so, i think i've managed to save everything important. that's the most important thing.
on second thought, though, i am going to move to a new drive, and relegate this one to emergency backup. i probably should have done that some time ago, i guess i just needed the smart test to fail to get me to do it.
i mean, that's what this is there for - to tell you it's dying, and backup and replace. i have a backup that i was intending to move to soon anyways...
