Why Hard Drive LED Light Flash Always
When you are using your computer (you are using your hard drive), it is completely normal for the HDD LED light to keep flashing on and off repeatedly from the system tray. This means that your hard drive is working, i. e. there are some reads or writes of data going on on your hard drive.
Sometimes, you would have noticed when you stepped away from your computer and after some time came back and see the hard drive activity light constantly blinking. I would like to tell you, it’s also quite normal and there is nothing to worry about this. All usual Windows systems do this regularly. Yes, of course, there might be a possibility of malware. if you’re worried about it too much, you can run an antimalware scan any time.
When you are not doing anything on your computer, the computer may have some background tasks to do. Upon this issue, your computer is behaving smartly. It waits very politely until the background tasks are finished. So you see the flashes of the hard drive led indicator, in spite of the computer being idle sometimes.
What Is It Doing in Background
I have mentioned above about the background tasks of your computer. So what does your computer do exactly in the background? These tasks basically depend on which software you have on your PC and their configurations.
Some of the common background tasks are described for you the below-
Index Files
All the operating systems of modern times include file-indexing services usually. This has been a common process actually. The process crawls through the total hard drive of your PC and includes the tasks like examining each file, the text inside it, and making a database. You will realize it; you get fast and instant search results of data from the PC database when you use the search feature of your operating system. Forgiving you this service, the indexing service has to visit your files, index them as well as watch them for changes which ultimately cause hard disk activity.
Defrags HDD
In the past time Windows, before defragmenting your hard drive, you had to close other programs on your computer. Modern times Windows has a great improvement in this. The present Windows in the background do the disc-fragmentation automatically while it is necessary. Though it is configured to do this at a particular time when the computer is idle.
Antivirus Scan
Security tools like antivirus programs are often scheduled to do antivirus scans on a regular basis by default on your computer. When your computer is idle, maybe your antivirus tools are working, probably it is sorting through the hard drives and examining the files in it. That also indicates hard disk activity.
Backing Ups
It actually depends on your set-up configuration. If you have those automatic backup setups in your computer, at the idle time, your back-up service might be doing a usual backup.
Auto Updates of Windows
I hope you know that the Windows itself and also many other programs like Google Chrome have the automatic updater. Sometimes, it’s good and sometimes feels odd for many reasons. So if you see some hard drive activity when your PC is idle, maybe somewhere in your PC something is downloading or updating without your knowledge.
In the above, I have described only five things that a computer does in the background. The number can be many depending on the software collection of your computer and their configurations. And so there will be hard drive activity too.
