New microSDHC UHS-1 won't work

I installed a new microSDHC UHS-1 card in my Zoom H1 audio recorder and it didn’t do anything. I tried reformatting it from the SanDisk website and was met with the mysterious instruction for my “Sansa” . . . except I have no idea what a “Sansa” is, so I went the ‘format from a pc route’ and got the same result. Did I commit an operator error, or what. All the topics I looked at now claim to have been posted three years ago. I’d rather not wait that long for a reply, if possible.

when it is connected to the computer is the card recognized? can it be formatted?
