It’s a hybrid sleep/hibernate system that causes more problems than it should.
Not all hardware works with it, it causes problems with updates and some software does not play nicely with it.
I know of a number of business IT departments that disable it company wide as it is a considerable source of problems.

It’s likely been set up as a Windows software raid array which I believe you have to do some janky work arounds to get them recognized.
Linux is seeing it as an unformated JBOD.
Your best bet would be to use Windows to move everything off the drives then wipe & re-set it up under Linux.
