Wd question

What is Model 1608A

That does not look anything like a WD Model No or P/N

A WD Model number starts with WDB … etc (see here)

If you can’t read the label …
connect the drive to you PC and download and run Data LifeGuard Diagnostics

And it will show you the full Model , Serial Number and Capacity

Thanks for that. It worked. Best wishes, Brian.
