@Mike_Eade - @JoeySmyth gave the most common way people get their serials (for internal drives it’s a big time saver vs taking the drive out of its case).
Another common thing people do (especially when they don’t have access to a PC with Windows) is to use the digital camera on a smartphone or tablet and “zoom in” on the serial number.
Yep, a good cell phone camera and good lighting above takes a great picture, and as was said, zoom in to take photo and then zoom in on the photo that results. a good tablet works well, too, and picture is larger…
I have iPhone and iPad and had to take a picture of the serial number of a new Chromecast where the faint S/N was along the curved edge. Ridiculous, but cell phone got the job done
