how to wipe clean a previously used SSD?

The Synology Forum location has changed, are you looking at the old site? The new site is: https://community.synology.com/

Do you have access to a Linux computer that you can attach your USB dock to? You may need to change the boot record partition when reformatting the drive, e.g., Master Boot Record partition. The Synology may have modified this to one that Windows cannot read. Had a similar problem on my Mac with a USB thumb drive.

Seems to me that if the format is the problem (quite likely), then you need to use a method to boot into Linux. I don't know how much Linux knowledge you have (mine is very limited) but I guess I would try creating a Linux thumb drive to boot off of and see if I could then access/reformat the drive. Seems like the AV forums has some useful help available. I wonder whether you could have reformatted the drive while it was still in the NAS and changed the format to something Windows friendly? I am assuming that you don't have access to a Mac computer either, sometimes a Mac will allow you to reformat the drive but you must make sure that you change the boot record partition to something that Windows will read. Good luck and sorry I can't be more help!
