When your computer Freezes?
my question is, when you computer freezes whats the safest way to shut it down? and whats the safest way to shut your computer down in general?
Hearing a whirring sounds from your hard drive when you try to so something is bad and i think thats caused from turning your computer off improperly correct?
Shutting your computer down improperly only does damage to the software, not the hardware. I think...
Whirring noises can usually be attributed to your fans. Try opening your computer up and cleaning it. Carefully.
In theory, all hardware since......... idk, probably Pentium II or maybe sooner (actually... I think they could do this on 386's, so no worries) should be smart enough not to damage themselves durning an improper shutdown. When you shutdown normaly, the OS calls for the power functions of the BIOS to tell the Hard Disks to shut down, so they will stop spinning and the read/write heads will dock before the computer shuts off.
During an improper shutdown, this is not called, but the HDs should still be smart enough to realize that power is gone, so they better dock. I mean... they even have enough time (99% of the time) to dock when the power is cut.
The biggest risk is shock or surge. So no kicking the computer or leaving it plugged in during an electrical storm (unless you have a huge rated suge protector). Other than that... not a whole lot to worry about as far as damaging your hard drives... other than magnets... forgot about them. No magnets on your case... don't care how pretty or cool they are. Get stickers.
Lastly, the sound you heard was probably the fans (like Tayuya said) or the motors in the hard disks slowing down, then spinning up again. So long as the motor for the actuator arm doesn't fuck up, you should be ok hardware wise.
