I would not call it "lock". Normally it is done using file system permission. Do you need to modify volume permissions programmatically?

I don't see any practical sense in doing so. It could be done statically by setting different volume permissions for different volumes. In this case, the required operation would be log out and log in as a different user. If the permissions for a volume should be done for more then one user, you could create groups and assign permissions for groups. Any system administrator can do it.

Would you also consider the hardware solution? These days, it is not very expensive to have a desktop, server or industrial-grade computer with hot-swappable hard drives. (Even my own notebook PC has this feature which I consider very important to me.) Each shift could use its own separate hard drive and swap it when a shift is changed. I personally would highly prefer such hardware solution to anything else.
