Windows 11: External USB Drive goes to sleep too fast. How do I change it?

I have a 1TB External hard drive connected via USB.
Formerly, this same drive was connected to a Lenovo W540 running Windows 10 Pro.
I've been using this drive for roughly 8-9 years so it's just a basic 5.25" hard drive mounted in an external case. It does not contain any of the latest bells or whistles of newer external drives.

I almost never experienced any lag or delay in Windows waiting for the drive to wake up.
It was never a problem, so I didn't specifically time it.

However, I recently upgraded to a Lenovo T16 running Windows 11 Pro.
Build: 26100.4946
Experience Pack: 1000.26100.197.0

Ever since I connected this external drive to my new laptop, Windows puts it to sleep after only 3 seconds of inactivity.
This is SUPER annoying and very time consuming as I can't even work on files located on C: without Windows pausing while it wakes up the external drive (D:).

I've searched online for solutions and all of them seem to be tailored to newer external drives as they refer to sections of the Advanced Power Settings my installation of Windows does not provide.

Please help me!

TIA

    Dear Brian Myers,

    The behavior you're describing—where the external USB drive sleeps after just a few seconds of inactivity—is not typical and may be influenced by power management defaults in Windows 11, particularly on systems using Modern Standby. Some legacy drives may not respond well to these newer power models.

    To help mitigate this, we recommend the following steps:

    Device Manager Settings Open Device Manager, expand Universal Serial Bus controllers, right-click on each USB Mass Storage Device, and select Properties. Under the Power Management tab, uncheck “Allow the computer to turn off this device to save power.”

    Power Plan Adjustments Navigate to Control Panel > Power Options, select your active plan, and click Change advanced power settings. If available, expand Hard disk > Turn off hard disk after and set the value to 0 (Never). On some systems, this option may be hidden due to Modern Standby.

    Third-Party Tools If built-in settings are limited, tools like NoSleepHD or KeepAliveHD can help keep the drive active by periodically writing small files to prevent sleep.

    I hope this helps. Just kindly tick Accept Answer that others in the community facing similar issues can easily find the solution. Your contribution is highly appreciated.

    Best regards,
