What is hard drive activity light?
Definition of an HDD LED & How to Figure Out What the Lights Mean
The activity light in a hard drive is a small LED light that illuminates only when data is written or read from the hard drive or built-in storage.
In some way it’s helpful when you know when your hard drive is being accessed by your computer so that you prevent pulling the battery or unplugging the power of the computer at the time when the Operation system is accessing the files from the drive, and if you did any mistake of unplugging power or anything that can lead to corruption of important files. The activity light is sometimes called a hard drive light, HDD LED, or a hard drive activity indicator.

Where the HDD LED Located?
You can see the front side of the computer case where the activity light is usually positioned. But on the laptop, you can see the HDD LED near the power button, or sometimes along with the keyboard or mostly on the edge of the computer. While on the tablet and all other small form factor computers, you will encounter the hard drive light at the bottom or on the edge of the drive.
Flash drives, Network-attached storage(NAS), External hard drives, and all the external outside computer storage devices also have the LED activity light indicator. But the smartphones do not have this activity or HDD LEDs.
The normal colors of the LED light can be gold, white or yellow, or any other color depending upon the type of hard drive, device, or computer you have. But in very fewer cases, these indicators can have a green, red or blue light.
If we talk about the shape mostly it’s a small circle or an illuminated icon of a hard drive. Mostly you will see it shaped like a cylinder or a cylindrical platter (stack) that represents the hard drive that stores data.
Sometimes you may also come up with an activity light labeled as HDD but it’s very rate. Unfortunately, must always differentiate between a power LED and HDD LED, the behavior shows that HDD LED keeps indicating when a hard drive comes underuse.
Understanding the Status of Hard Drive Activity Light
As already told that the hard drive LED activity light indicated only when the device is being used. But don’t take it as diagnosing a computer issue.
If you encounter the activity light perpetually lit, consider that the computer or the device is frozen or locked up.
Mostly you have to restart it manually, which will occur by pulling the power cable or detaching the battery.
If you in some way have any access to your computer, then must restart by the proper way and have a look that the problem goes away when you start it again.
The normal behavior of the activity light is to flash on and off repeatedly, all the way you use a computer. This behavior shows that the drive is being used to read data or write data, which happens only when the set of things are occurring like, Scanning the drive-by antivirus, disk defragments program running, backup software backing up files, the software is being updated, files are getting downloaded and many other things.
You will see sometimes the activity light flashing while you are not doing anything this is because when you are dealing with your tasks the windows OS waits and keeps itself idle and after you have finished it starts its tasks. You don’t need to worry about it, sometimes it can mean the malicious thing is happening without your knowledge, that’s when you need to scan your computer for malware.
