How to tell which hard disk the \Device\Harddisk18 refers to?

We have a Win2012R2 with a Spaces Storage of 16 hard dives (RAID0 via Dell Perk 6i). The Spaces Storage is a backup storage. Recently our backup failed on some backups due to corrupted backup files so I got in the event log and found there are some Event 51 warnings:

An error was detected on device  \Device\Harddisk18\DR95 during a paging operation.

Since all the warnings point to the single harddisk18 I tend to believe the harddisk18 is likely with issues. But the problem is, which disk is Harddisk18 ? And there is no disk error message somewhere else. Can you help please?

Thank you for the info. Though the article seems to be pretty old so not very accurate to Win2012R2 environment. I found a post in another forum

https://social.technet.microsoft.com/Forums/azure/en-US/2e3d2e68-a4e7-49b7-9d70-7b70c166a1c9/how-to-find-out-which-hdd-is-deviceharddiskdr-?forum=winservergen 

that mentioned using WinObj.exe to locate the Harddisk# but the problem is, I couldn't find Harddisk18. Does anyone know why?

From the same article did this Powershell command not do the trick?

Does it mean "Storage Space"?  In server manager you can instruct a particular HDD to blink the indicator light:
