Back your shit up!
Friendly reminder that you should make sure that you have your precious pictures backed up externaly.
Just yesterday after a blue screen for god knows what reason, Bitlocker in Windows, which I've used to "protect" my data, suddenly decided to enter a blue screen cascade that gave me the fuzzy feelings. Luckily, the data decrypted completely in the end, after plenty of spontaneous reboots.
Of course, like any good IT guy, I didn't have a backup.
