Q&A 1 – Card not recognized by computer
The issue could be the card is not recognized on a card reader.
1. Memory card locked or write protected? If you see “SD card locked” on your digital
camera or “The disk is write-protected?” on your computer, you should turn off the
write-protect lock.
2. Insert the card into a UHS-II card reader, and connect the reader to your computer.
We suggest using a Lexar Card reader for confirmed compatibility. If the connection
works fine, open the Disk Management on your computer and check if the capacity
and the formatting with SD Formatter tool is successful.
3. If you cannot format the card and there is no appearance damage, suggest
contacting Lexar Technical Support for RMA process.
Q&A 2 - Card not recognized by camera
1. It’s important to choose the right card for your camera. Please refer to the Lexar
Compatibility Guide on Lexar.com or your device’s user manuals to choose the right
card for your camera and applications. If you choose an unsuitable card, it will cause
the continuous high-bit video recording to record slowly and cause dropped frames
or loss of data.
2. Make sure the card's file system is compatible with your camera. The file system of
RAW will not be recognized by a camera.
3. Check whether the card is caused by poor contact: whether the card is fully inserted
into the card slot, or the card PIN is dirty.
4. Connect the card to the computer with a UHS-II card reader. If the card is
recognized by computer, check if the SD Formatter tool works normal. If you can
format successfully, insert the card into the camera to check if the card works. If you
cannot format the card, suggest contacting Lexar Technical Support for RMA
process.
