closing command prompt in the middle of an operation

On the last drive now. I guess I'll be careful and not close the command window if something is running. Still not sure if I "broke" anything.

Running sfc now following the tutorial:
SFC /SCANNOW Command - System File Checker

Found no integrity violations (ran 3 times).

There is a way to know what is running in the background.

Press+Hold both Ctrl + Alt and press Del.

Select "Start Task Manager"

I know that. I was wondering what happens to the command that is running if you accidentally close the command window. I checked task manager after closing the window and cmd.exe was not running but the light on the HDD dock was still flashing like it was doing something.

There is no need to worry about these programs still running or not.
Not only on Windows window, it still check on DOS mode in Windows.

As to my knowledge, if the HDD light is flashing, this means that the system is reading the HDD, not writing.
When the HDD light is on/stable, this means the the system is writing to a particular HDD.
This problem will arise if you have more than 1 HDD.

But all this is not to worry on whether it will damage your HDD.
As to what i means, if there is 2 or more internal HDD, as to which HDD is still running active programs.

For External HDD, you can see light on the External HDD, flashing or not (option).

When you click "Shutdown", the system to check for any programs still running in the background.
If it there is a program is open, the system will find a way to end the programs SAFELY, a few seconds more to turn off.
It may not corrupted any HDD(s) and the system will only shutdown after terminating the active program.

I am use to do straight power off, without the shutdown command, as i know what is the programs i want to terminate.

Note:
If the system did not do a proper shutdown command.
Upon next boot up, the Windows would request you to choice on Safe mode, or normal mode.
Usually i choose normal mode to boot into Windows OS.
After the Windows OS boot up without any problem, i will do a shutdown; then boot up again.
In this way, the system know that it had done a proper shutdown, and no prompt on boot up again.

The activity light for the external HDD dock is what I'm referring to, not the HDD light for the computer.

Same as internal HDD.
Flashing is reading. Will not damage the HDD if sudden power off.
(My previous company IT Administrator just unplug the Ext HDD /devices, as he told me it is not a problem.)
Stable is writing, as best let it finished.
