How not to make a mistake when disconnecting a hard drive?

Question

RAID

The system unit has two identical solid-state SSD hard drives. They worked in RAID1.
Right now one of them is drive C, the other one is D, Winows XP OS.
Task: hot (without restarting the system) disconnect disk D.
Question: How to determine which of the disks in the system is disk D.
The SSDs themselves have indicators that are constantly lit when the power is connected.

Answer 1

In my opinion, in various disk managers under Windows there were auxiliary inscriptions, for example, this disk is connected to a blah blah cable and entered into a blah blah RAID array ... Perhaps this will help you ...
If not, then through the BIOS.
