Roku Ultra 4, can't format new microSD card

Fri Aug 09, 2019 8:50 am

When I insert a brand-new 32GB SDHC microSD card (smallest memory size available at my local computer shop) into the slot on my new Roku 4 Ultra, it recognizes the card, prompts me to format, and then times out at 10%. Then it displays the message "Unable to format your microSD card for use with this Roku player." Card works fine on other device. Any troubleshooting suggestions?

Have you tried reformatting the card in another device, then reinserting it into your Roku again and seeing if it is able to successfully reformat the card? If that isn't working, I'd recommend trying a card from a different manufacturer. Many options are available online via Amazon, etc. 

If you're in the US, we also offer them on our accessories page here: https://www.roku.com/products/accessories/player

Roku devices are VERY picky as to which cards work with them. Check old threads here to see which cards work best.

Here's one:

Btw, are you speaking of a Roku 4, or a Roku Ultra? There's no such device called a Roku 4 Ultra.
Yeah, I got some Rokus.

Not just Roku in particular but it's common for devices to reject certain SD cards.  Check your documentation for approved and tested cards, I've had good compatibility results with Sandisk SD cards in general but I haven't tested one specifically with a Roku.
