comment Half-formatted HDD, what should I do?
Ah, yeah, I misread. smartctl doesn't work with (I assume) USB external drives; SMART commands aren't passed over properly. If your drive is as new as it is, it's quite possibly still under warranty. That'd be the best route to take, if possible -- failing that, you'll have to fire up mkfs with the -check option again and just wait. You definitely could have gigs worth of sectors blocked off at the fs level, if you really wanted to wait that long & were certain more won't pop up. Either way, consider this drive temporary storage at best; future silent corruption sounds very likely.

comment Finding out if a FLAC or WAVPACK audio file is NOT originally encoded from a lossy source
1+ re: frequency rolloff. As a quick test, loading any suspect file into any media player with a spectrogram visualization plugin (foobar comes to mind) will likely show a complete absence of any higher frequency components to the file in question, as well as a flat-topped cut-off appearance to primarily high frequency things like cymbal hits.

comment Battery on or off while running the laptop on electricity?
It can be, if you're working on an unsaved file and the power goes out. Generally, your biggest risk is losing unsaved data. Damage to your hardware is unlikely. If you want the laptop battery to last as long as possible, I would suggest you consider purchasing an Uninterruptable Power Supply (UPS), which uses big, heavy lead-acid batteries that last forever to provide AC power. If that's not an option, you certainly can leave your laptop battery in all the time, but it could shorten the useful life of it quite a bit.

comment Freezing a dead(ish) laptop battery
The battery calibration cycle will, or should do that, then. If your BIOS doesn't have an explicit option to do so, running the battery down from "100%" (wherever it stops charging) to "0%" (wherever you can't power the laptop on anymore). This may or may not work, though; I assume it's happened naturally a few times already. The battery may just need out-and-out replacement.

comment Freezing a dead(ish) laptop battery
I suppose my answer wasn't quite clear enough, sorry about that; freezing your battery will do absolutely nothing for it's capacity issues. It has irreversibly lost some of it's capacity due to regular degradation which is to be expected in all lithium-ion batteries. At worst, freezing it might cause it to short out due to condensation, which could lead to fire or explosion or other nasty things. So, to answer how long you should freeze it: Approximately 0 minutes and 0 seconds.
