I'm running a dual-boot setup with Windows 10 and Linux Mint 20.2 Cinnamon and encountered the problem that when I'm booted into Linux, I can mount and read drives without problem, but I can't write to them. This problem persists even as root and no matter the mount options.

This is a well-known problem, did you search Unix for former solutions? Because if there is, it will be marked as off-topic directed to SuperUser, or duplicate.Vlastimil Burián– Vlastimil Burián2021-09-29 12:06:41 +00:00Commented Sep 29, 2021 at 12:06

Yes, I searched quite a while online, tried a ton of different stuff but nothing worked. I never found this solution online. I got it from my brother who said this could fix it, which it indeed did. I only posted this in case other people who run into the same problem also have a hard time finding a solution.SV-97– SV-972021-09-29 12:12:13 +00:00Commented Sep 29, 2021 at 12:12

This is ultimately a result of Windows using the drives to cache some data so that it can start up faster. It can be fixed by changing some settings in windows.
Start by opening cmd as admin and execute powercfg -H off to turn off the hibernate feature. Next navigate to the power options in the system management and deactivate fast startup as well as the standby mode. When booting into linux, the drives should now behave normally.
Furthermore you might want to consider not using the regular windows shutdown, but rather doing a reboot when switching from windows to linux as @LinuxSecurityFreak explained in the comments.

Even if you turn off Fast startup, reboot from Windows and booting Linux is always best solution.Vlastimil Burián– Vlastimil Burián2021-09-29 12:07:45 +00:00Commented Sep 29, 2021 at 12:07

Further, it is untrue, that Windows is not properly shutting down drives, it's just using the system disk to start up faster next time.Vlastimil Burián– Vlastimil Burián2021-09-29 12:10:24 +00:00Commented Sep 29, 2021 at 12:10

I don't get what you mean by your first comment. You mean not shutting down windows via a regular shutdown but rather a reboot and then just cancelling this windows reboot and booting into linux? Why?SV-97– SV-972021-09-29 12:14:14 +00:00Commented Sep 29, 2021 at 12:14

Reboot skips the fast startup feature and all possibly other prefetching mechanisms.Vlastimil Burián– Vlastimil Burián2021-09-29 12:16:15 +00:00Commented Sep 29, 2021 at 12:16
