I don't know where to post my question. I apologize if I post my question in the wrong forum.

I have a hard drive from a laptop with Linux. (I burned its CPU after trying to run multiple servers on the laptop.) With an adapter, I can boot the Linux distro on a desktop and use the OS as usual other than no sound.

I would like to have the drive as an external hard drive so that I can back up my files from other Linux boxes. I, however, can't save a file to the hard drive, nor run the access permission change command "chmod" due to the permission restriction.

Is a way to change the access permission in the hard drive?

if you want the files from it you will need a linux system as windows refuses to acknowledge any filesystems other than it's own. if you just want to wipe it and use it for windows then just do that as you would normally. windows 10 disk management, and create a partition. this will wipe the drive though, just keep that in mind.

I shall clarify that I mean accessing from a Linux box (updated my post). In Windows (10), the external HD is unvisitable in the Windows file explorer although the Windows system detects the HD as a device.

You need to run chmod, mount, and other such commands as root. As a user, you can only control drives that you own. You need to log in as root, or use sudo if your distro supports it.

It is so simple. I was thinking about something else after some headaches on Linux tasks.

Right click on your external hard drive
Choose Properties from the contextual menu
Click on Security go to Edit
A dialogue box will appear as Permissions for a new volume
Click on the Add button add a new user name and OK.
