Chances of a mistake in disk management do indeed go up exponentially when/if drives are the same size, 500 GB in this instance...; however, each drive listed (Disk 0,1,2, etc.)can be clicked on , and the 'properties' tab selected, and the specific model number/manufacturer will be listed (Samsung, HGST, ST (Seagate Technologies), etc...)
That would
still leave a chance of a mistake if/when, for example, two WD drives of equal size were used, however...
...as there is no predictable way of knowing which drives are listed in seemingly random order within disk management... (My own HGST 4 TB storage drive is listed as drive 0, an extra laptop drive for tinkering is drive 1, and the Samsung NVME OS/C: drive is drive 2....)
When connecting the drive, do completely power off the rig, to include a shutdown
AND removing power cable from rear of PSU , to ensure nothing goes wrong when connecting the drive's SATA power cable and SATA data cable to an available mainboard port... If you do not have a spare SATA power cable, and need to add one to a modular PSU, make sure you use the ones provided with that PSU, as the pinout at the PSU end is often different, which can quickly fry a drive at power on when/if wrong/incompatible cables are used!
