Hardware resets won't damage the drive.

Cycling the power could corrupt your file system though, if you had write caching turned on. But hitting the reset button is safe.

No a hardware reset cant physically damage your hard-drive. If the drive was writing data at the time then it could result in data corruption, but not physical damage. Run "chkdsk c: /f" to check for file system corruption after the event.

thanks

i read in a lot of forum ,that a reset after an intense hd job , could damage mechanic engine & platters

That's simply paranoia. Hard or Soft resets can do nothing to damage a hard drive. Data corruption if it comes will be a result of interupting the operating system before it finishes sending data to the drive (anything in the operating system cache will likely be lost). Any data already sent to the drive will be safe.

This is taken and applies to Apple Macs but may be helpful:

The PMU is very sensitive and touching the circuitry on the logic board can cause the PMU to stop responding. If the PMU stops responding, the battery life goes from about five years to about two days if the PMU is not reset. The PMU chip is located near the battery; refer to article 95035: "Power Mac G4 (AGP Graphics/Gigabit Ethernet): Logic Board Diagram" for the location of the PMU button.

Many system problems can be resolved by resetting the PMU chip. Whenever you have a computer that fails to turn on, follow this procedure before replacing any modules.

Resetting the PMU Chip Procedure

1. Disconnect the power cord and check the battery in the battery holder (BT1). The battery should read 3.3 V to 3.7 V. If the battery is bad, replace the battery, wait ten seconds, and then reset the PMU (refer to the next step). If the battery is good, go to the next step.

2. Press the PMU reset switch (S1) once on the logic board. Do not press the PMU reset switch a second time because it could stop the PMU chip from responding.

3. Wait ten seconds before connecting the power cord and turning the computer on. If the computer turns on, go to the next step. If the computer does not turn on, there is something else wrong with the computer.

:blink: what it is a PMU :blink::blink: ?

Forget about it. Nothing in that post is even remotely relevant to your question.
