I have removed a 500 GB Barracuda internal hard disk drive from my old laptop
This is an actual spinning magnetic hard disk and not an SSD
I have a USB converter cable for it that lets me connect this drive to the PC through USB, like a USB drive
If I eject this drive through the "Remove Safely" button on the Windows taskbar, I get the notification that it is safe to remove this device and the drive icons disappear from my computer, but I can still hear some rotating sound from inside the hard disk. I still need to get close to the disk and listen carefully to hear it though. Is this normal sound for this kind of hard disk? If I unplug the USB cable I cannot hear anything and since I am sure it doesn't have any kind of fan inside I think it is probably the sound of the disk still spinning. Is it safe to unplug the USB even though I can hear this spinning sound? Is there any way to comppletely turn the power off to this drive before unplugging it, after performing the windows safe to remove function?
The connector cable looks something like this:
