Hey there, nowiknow.
Please check if the drive is recognized in Disk Management and Device Manager and post screenshot of what you see there (you can use imgur.com to upload the image). Here's how to access them:
How to access Disk Management in Windows to manage hard drives &
How to access Device Manager in Windows.
You could also try connecting the drive internally via a standard SATA connection (if it's a SATA drive), to see if it's recognized properly this way.
Hope that helps. Please let me know how it goes.
