In this post, we will see how you can prevent your primary, secondary, or an external hard disk drive or USB from going to sleep on a Windows 11/10/8/7 computer. You do not want your external hard disk going to sleep, and yet you find that at times it goes into Sleep mode. Sleep is a power-saving state that lets you quickly resume full-power operation when you want to start working again.
Does the hard drive stop in sleep mode?
Yes, it does, and it applies to SSDs and mechanical hard drives. By design, the power plan ensures that when the PC goes into sleep mode, the storage also stops working unless triggered by a wake-up call. Some PC also offers. That said, Windows offers Modern Standby or Connected Standby power model that offers low power idle mode, similar to the smartphone experience. It allows some of the background processes to keep working, e.g., ensuring you get emails.
Prevent Hard Disk from going to Sleep
To stop or prevent the Hard Disk from going to sleep, click on the Battery / Power icon in the taskbar, and select More Power options. In the Control Panel windows which opens, select Change Plan settings for your current Power Plan. In the next window, select Change advanced power settings.
In the Power Options box that opens, click the + sign next to the Hard Disk option. Here you will see the required settings under Turn off hard disk after heading. Change the value to 0.
On recent Windows 11, you may see the following setting and you need to set it to Never.
Click on Apply > OK and exit.
This setting will prevent your hard disk from entering the Sleep mode.

Can you leave an external HDD plugged in all the time?
Yes, keeping an external HDD connected all the time is absolutely ok. The only thing you need to ensure is if the disk is in use i.e., Backup, File transfer, then it should not be disconnected from the PC or Laptop. If you do that, file corruption or drive issues are likely.
