What, if anything, do those same few drives have in common?
Do they share a specific drive model, that differs from all other drives in your farm?
Do they share the same controller on your PC?
Also, some drives are hard coded to go to sleep, short of getting written to periodically.
There are no Windows settings that will keep them awake.
I have a few such drives, and I have a keepalive.bat script that cycles every 100 seconds that copies a few bytes of data to each of those drives. Now they never sleep.
To see if the drives are sleeping, have a command ready for you to simply have to press enter to kick off a file copy job. If, when you copy the file, there is an initial delay, then that drive was probably sleeping.
I recommend “robocopy.exe” for such a test, because by default it will show you the progress of the copy job. It makes it easy to see if there is a delay getting started.
robocopy.exe is included in Windows 10. I do not have Windows 11, but it is probably there, too.
from the command prompt for the syntax.
A lot of info will get displayed, due to all of the options. You will not need them. The top of the help output is all you will need for your test.
Note that if you “cd” to a directory on that drive, that action might wake up the drive, which will invalidate your file copy test. So set everything up, and wait 30 minutes or so. Then press enter and see if the file copy happens instantly, or if it hesitates to get started.
I suggest that the source of your file copy test be an SSD drive, to eliminate the source drive from being a possible factor in any delays.
