Logical Disks

[Jeremy]

I have a logical disk that appears in Storage\Logical
Drives but not in Storage\Disk Management. Why is that?

You need to distinguish between "disk" and "drive".

A "disk" is the physical thing, something you buy,
something you can touch. You can see it in Disk Management.

A "drive" is an area on a disk. A disk can be partitioned into
just one big area, or into many. These partitions are then
called drives. Hence your physical disk can have drive C:,
drive D: and drive E:. Some of them may be called "logical
drives", depending on the exact configuration. Here is
the configuration of my own PC:

drive c: - a partition on the first disk
drive d: - a further partition on the first disk
drive e: - CD
drive f: - a partition on the second disk

Here is my configuration (from Disk Management)

Disk 0: C:, F:, E: - these are partitions on a Hardware RAID 5 array consisting of 3 physical disks
Disk 1: F: - this is a single disk

When I open Explorer or look under Logical Disks in Disk Management, I see this M: drive

This is an Exchange server.

The obvious thing to do would be to right-click it in Explorer, then to
click "Properties".

The M drive is created by Exchange. It is normal and not of concern.
