My laptop just went through a BSOD and I've been noticing a noise from the hard disk even before the BSOD. Dump says the process that failed is ntoskernel. That's no help.
SMART test said hard disk state as OK but crystaldiskinfo says the following which confused me even more. Is it supposed to be this way?

As you see, the current is higher than worst? Is it supposed to be that way?
Also what is threshold? Is it the ideal maximum?

Can't help you there, never quite understood the arbitrary values on smart. But, in my experience, clicking or just out of the ordinary sounds do mean the hdd is reaching it's useful life end.
The power cycles and powered on hours are high too, even if windows is not logging crc errors, I'd start thinking about replacing it, you can always use it as an external drive with a cheap adapter.

@filthyranter which attribute gave you that info? I got the 6030 hours but not this.

Damn! I've been doing the hex to decimal conversion everywhere and didn't notice the top.
