Sorry that's not how the mount command works on Linux. It's not always easy to tell the device associated on linux either. Sometimes you need to look at dmesg output. Unfortunately cygwin has nothing similar.

The wodim command from the cdrtools package includes logic (-scanbus option) which is able to identify SCSI devices under Cygwin. It doesn't map them to the /dev namespace, but it shows that something like you need may be possible. Wodim is also able to take a drive letter and directly use that when writing an ISO file to the drive.

Maybe you could start there and craft a tool to do what you need.

That might be the easiest way to creating a tool, since you'd have existing logic to leverage. But to answer your original question, you can certainly use the information from Disk Management to figure out the mapping.

should help in that regard. But essentially, "Disk 0" = /dev/sda, etc.
