REMOVING THE microSD CARD

Carefully remove the microSD card by using a thumbnail or pencil eraser to push the card in so
it will spring out. Handle with care if you are going to use it in a card reader. Gently install the
microSD card the same way it was removed and to push the card in so it will spring back into
place.

Reformatting the microSD Card

Reformat microSD cards using a special SD Card Formatter (https://www.sdcard.org/downloads/
formatter_4/). Then, you need to “Clear User Data” using Sentinel to restore all HP les and
directories to the card.
After formatting, the HP won’t be automatically detected (since it is wiped clean), so you may need
to uncheck “Hide empty drives” in windows “Tools>Folder Options>View before doing the “Clear
User Data” step.
