If this is the case, the card is probably too new for the game camera too, as we just bought it but it was first sold 8 or 9 years ago. Is my problem that this card is an Ultra, or is too fast, and my 4-year-old (unbranded) adapter can't read it? I am asking you because my google search of this issue turned up many offers of a third-party solution, and it seemed unlikely that I should go that way. The computer does not see that there is anything in the drive. I tried removing and reinserting the card in the adapter, and doing the same with the adapter in the reader. When I insert the card into the adapter a red light comes on. I don't remember if I have ever used a Microcard before, but the adapter has no problem with regular SD cards, and the ones I have been using in it for the past few years are regular-size 32 GB class 10 (for my 11 year old video camera). There is a groove in it just at the edge of the holder, right where my fingernail goes to take it out, so I'm pretty sure I got it in right, and the holder inserted just fine into the multicard adapter on the computer. I inserted the Micro card into the adapter with the label up (showing the same side as the label on the adapter).
A multicard reader was added when I had the computer set up for me in the shop. My computer is an HPZ800 that was given a new role with me 4 years ago as a desktop. Instead of Class 10 it says the speed is "up to 98MB/s". I got a Sandisk Ultra with a standard-size SD card adapter. It specifies a class 10 card and recommends 32mb. I need to format a MicroSD card for a trail camera.
