Thank you all for your responses.

Yes, I have tried formatting the card. It comes pre-formatted with extFAT. The camera recognizes it fine. After a few shots then it will give the "memory card error" and would shuts down.

I have tried formatting it to NTFS, which of course is not supported by the camera, and it says "the card is not formatted" or "the card needs to be formatted". I then used the camera to format it, and then it is recognized. However, same problem persisted.

I have tried full format using my PC, even force format it to FAT32. The camera will only accept extFAT for the SD-XC card. Which I checked on the net, for SD-XC cards it defaults to extFAT and not recommended to be force formatted into FAT32 as FAT32 does not work properly for storage size > 32GB.

I think the SD-XC card itself is okay. I have tried copying some files using my PC back and forth, no problem at all.

At the moment I'm trying to connect my camera via usb to my PC and re-format (full) the card, extFAT of course, and see what happens.

Could it be firmware issues? I've tried pentax/ricoh global support, but not very fast response

Hi,

I have an Option WG-3 GPS model, just bought it 3 weeks ago. I've checked the specs and it says it supports SD-XC cards. So I bought a Kingston SD-XC 64GB Class 10 card.

Unfortunately, it only allows me to shoot like 5-6 still pictures before giving me "memory card error" and would automatically shuts off the camera. I cannot even record any video longer than 10-20 seconds only on 1920/30 HD setting.

Anybody have any experience with Option WG-3 GPS and 64GB SD-XC card? I have an 8GB SD-HC card and it works perferctly.

Any inputs are most welcomed.

Thanks
Eddy
