SanDisk Ultra memory card - 256 GB

SDHC cards support capacities from 4GB to 32GB, while SDXC cards support capacities from 32GB up to 2TB. SDXC requires a compatible host device; it is not backward compatible with SDHC or SD slots.

While this card can record Full HD video, its 100 MB/s read speed and UHS-I interface may not be sufficient for high-bitrate 4K video recording, which typically requires faster U3 or V30 rated cards.

Insert the card into your camera or computer. Use the device's built-in formatting tool. On a computer, right-click the drive in File Explorer (Windows) or Finder (macOS) and select 'Format'. Always back up data before formatting as it erases all content.

UHS-I (Ultra High Speed-I) refers to an interface standard for SD cards that allows for faster data transfer speeds compared to older standards. The SanDisk Ultra 256GB card utilizes this interface.

This is an SDXC card. If your camera only supports SD or SDHC, this card will not be compatible. Please check your camera's specifications for supported memory card types.

The card is tested to be waterproof, temperature-proof, shock-resistant, and X-ray-proof, offering enhanced protection for your data against common environmental hazards.

Ensure the card is fully inserted and the device is powered on. Try formatting the card in the device if it's new or has been used in another device. Verify your device supports SDXC cards.

Check if the card is full. If not, try formatting the card (note: this erases all data). Ensure the write-protect switch on the adapter (if used) is not engaged.

Ensure the device's firmware is up to date. Use a compatible card reader for computer transfers. Avoid using the card for continuous high-demand tasks if it's not rated for them.

Stop using the card immediately to prevent further corruption. Back up any recoverable data. Consider using data recovery software. If the card is consistently corrupt, it may need to be replaced.
