I wanna turn off a write protection mode on an SDXC card

The 64 GB cards are not SD cards. They are SDXC cards and need a different interface. The card lloks the same, but the electronics is different. Your camera or any device you are using should be SDXC compatible.
On this page, scroll down half a page and look how the compatibility works for SD, SDHC and SDXC.

speed class choices.
about compatibility with host devices before choosing your card, it is important that you understand how to use your memory card to it greatest ability. sdxc memory cards and devices (digital cameras, video cameras, laptops, etc.) are now available. learn how to use your new sdxc memory card to optimize its performance.
confirm compatibility before inserting your sdxc memory card, confirm the device is compatible with the sdxc standard by locating an sdxc logo on the device or referring to the device's user manual or manufacturer information.

understanding backwards compatibility

• sdxc memory cards must only be used with sdxc devices.
• sdxc devices can use sd memory cards, sdhc memory cards and sdxc memory cards.
• sdhc memory cards can be used with sdhc devices and sdxc devices.
• sdhc devices can use both sd memory cards and sdhc memory cards.
• sd devices can only use sd memory cards.

the link above has several chart on sd cards.

If the card is a Secure Digital (SD), SDHC or SDXC there is a write protect switch on the card which can be slid up and down. Up means it can be written too, down means the card cannot be written too. If the card is in the position where you can write to it but the camera is saying the card is still protected it maybe a faulty card or the camera may have a fault.

Turning on or off the flash in IA mode is described on page 35 of the manual.

The XP10 works with SD cards, 2GB or smaller, and SDHC cards, 4GB to 32GB. It will not work with 64GB SDXC cards.

Wheb you have a SD, SDHC or SDXC memory card and you put the switch to the lock position, the card is protected, That means nothing can change the files that are stored on the card. Not by wiring, not by deleting and not by formatting. Keep the lock with up, towards the golden connection points.

Hi Nancy,

I have a couple of generic suggestions. First, make sure the SD card lock tab is in the "unlock" position. When in the lock (or sometimes called "write protect") position, it will not accept data to be saved.

Secondly, check to make sure that the card is a type that is compatible with your camera. If you camera specs an SD card, install and SD card. If it requests and SDHC card, provide and SDHC, and so on. There have been several versions of cards that all LOOK the same: SDSC, SDHC & SDXC. The "SDSC" (Secure Digital Stand Capacity - at introduction was called simply "SD" as it was the only capacity) type has a capacity of 4GB or less. The first devices could not access areas memory in the 4GB + range. Next came the "SDHC" (High Capacity) card. These cards were originally set for 4GB capacity and greater. As the older SD devices faded away, the low end capacity of SDHC cards dropped from 4GB to 1GB or smaller. The SDXC card (eXtended Capacity) and SDIO (Input/Ouput) will supersede the SDHC types as time advances.

Lastly, do not use card types (or those with greater capacities) that do not appear in a compatibility chart for the camera (or any device for that matter). When trouble arises, use only recommended hardware (memory cards) as shown in manuals or online info.

Good luck!

No. The S2980 works with SD cards (up to 2GB) and SDHC cards (up to 32GB). It does not work with SDXC cards.

To retrieve deleted photos from memory card you need a good recovery tool and it must suit your needs .I would like to recommend this because it gives good results in SDXC cards .You can download it here

Is it compatable, some devices dont like high speed SD cards, if it says SDHC or SDXC that may be your problem,
What is the maximum supported size you can use?
It may only be 2 or 4 GB
Has the write protect tab be knocked into the protect position?
If this is no help, please write back and i will look futher for you
