Re: Samsung Spinpoint F1 Errors ?
If this attribute raw value 159 doesn't increase anymore, then cable replacing did help and you have nothing to worry about. Other attributes look normal.

Seems to me that partition table, MBR (master boot record) or at least file system is corrupted. It could be just some missing or corrupted driver, but drivers do not become corrupted without reason - usually bad RAM or bad sectors on HDD are underlying problem. I would attach such HDD to another (w...

My personal take is that reliability issues aren't really brand-specific, they're model specific. I agree 101%.

With a LED backlight, current control is easier to implement for dimming. Yes, but unfortunately LED emission spectra depends on current and thereby PWM is used.

Not less, not more. So airflow is restricted by the bottleneck, the direction with the lowest number of fans....

Based on the lack of voltage drop at the brick under load, it is implied that the brick is somewhat stable, correct? Not exactly - without oscilloscope you cannot see short fluctuations.

Brick output (at cable connector) stays nicely within limits (5%, from 11.4V to 12.6V). Your DYI parts an Pico add just about 0.25V drop at full load, what shifts output voltage off the limits. Seems that motherboard and other components are designed without any reserve too. Thin connector leads sho...

@crankyhobo IMHO temperature coefficient indicates how "threshold" voltage (eg 5.6V) depends on temperature.

If I understand correctly (wiring is brick-connection-pico-mobo), then the largest voltage drop (about 0.4-0.5V) occurs in long cable from brick to your connection? If you increase power up to 180W (1.5x), then drop would be about 0.6-0.8V (corresponds to your other mesurements nicely). Can you take...

No-load voltage measurements are no indication. Voltage drops under heavy load (=big current), not while idling. 0.4 ohm is way too much (and must be wrong OR I can't exactly imagine your circuitry or both :)). When your system consumes say 120W, then DC current is 10 amps, on 0.4 ohm resistance vol...
