Not cutting off battery power has the potential, but it doesn't do it every time. Disconnect the battery to be sure, and hold the power button down. You need to reconnect to WiFi and reset the time(the battery acts as a capacitor in the Unibody machines) and the time and WiFi is a lot better then a $1,000 motherboard. Internat Time might help, but don't rely on it. Set it yourself, and then sync it with Internet Time, if it doesn't do it for you.

Not cutting off battery power has the potential to do damage, so it may be a good idea to disconnect it as a precaution. Just keep in mind you will lose your WiFi settings and time, but that's better then a bad motherboard.

I've done this with a T8 before. This is a stupid way to do it, but it worked for me at the time. Do not try it. You will probably ruin the screws. I would just disconnect the battery if you don't have the driver you need for it. You need a Tri-Wing Y1.

I've done this with a T8 before in a pinch, but it can damage the screw. You will want to use a Tri-Wing Y1 if you want to remove and replace the battery.

Your drive does sound like it's failing and SMART missed it. Back this up while you can. If this drive is slow, corrupting all the time and has filesystem corruption then I would seriously look into the drive. However, the HFS filesystem sucks at the same time. Sometimes you have to repair the filesystem by rebuilding it or reinstalling. If it still does it enough then I would replace the drive. Filesystem damage happens, but if it's constant it's the drive.

As to the hard drive it sounds like the drive is on the way out. Take a backup while you have a chance and replace it. In some cases it's filesystem damage since the HFS filesystem doesn't seem as robust as it could be so you may be able to get away with a filesystem and permissions fix. Do not count on this, but also do not be afraid to try fixing it with something like DiskWarrior. Worst cases, you have to reinstall OS X. Repeated issues are likely to be a bad hard drive.
They can be destroyed. Doesn't happen every time, but remove the battery to be sure. I would also hold the power button down too. The only downside to this is you lose your memorized WiFi connections. But would you rather not destroy a 900.00 board or keep something you can replace? You may also have to reset the RTC in Mac OSX but Internet time usually fixes it. Just be aware you may need to manually fix it, then let Internet Time do it if the timezone resets.

So yes. It can be damaged. It just isn't as common as you think. Removing the battery is still a good safety precaution.

i did this with my early 2009 17'' unibody for safety reasons,so unplug it

but i installed a 512GB SSD so i finally had the courage to get a SSD and boy,are they fast!

To everyone that helped me out with the harddrive potentially failing,it did start to fail so here is a tip,back it up quickly after it starts to give up!
-
One hint inconstant reading,corruption of files,filesystem corruption,constant reading,slower then usual

and these HDD drives silently fail!
