Is it possible to prevent a block device from being mounted writably?
I can't access secondary hard driveHow do I mount a hibernated NTFS partition?Cannot mount FAT32 system as 777Error openning my hard-driveUnable to Access my Hard DisksHDD mounting issuesUsing `umount` for USB mounted ext4 volume without `sudo`nbd-client Fsync errorUnable to mount external HDD due to unknown filesystemInstall Ubuntu (18.04) with option to add new OS in future - can't define 'device from boot loader installation'
Here is the story, I am using a Linux OS installed to my PC and a window-to-go USB HDD.
In desktop Linux, I sometimes use VirtualBox to launch the Windows installation as a virtual machine, which generally works well. VirtualBox access the window-to-go USB HDD, say /dev/sda as a raw block device.
The problem is, when VirtualBox is accessing the WTG HDD as a raw device, the HDD is still accessible in the hosting Linux OS. I can easily mount /dev/sda1 to some directory and write to it.
This makes the case extremely dangerous because the Windows OS inside VirtualBox and the hosting Linux would concurrently write to HDD.
I tried to set the permission of /dev/sda1 as 000, turned out that KDE dolphin can still mount the partition. I want to know if this is any way which I can reliably prevent any mounting operation on /dev/sda1, until I sudo the some operation to allowing mounting again.
