SD card compatibility in K20D

DeMadDog · 12-31-2010, 04:56 PM

I recently bought a Dane-elec 16GB class 10 SD card and my K20D gave me a "memory error" message. I sent the card back in exchange for another, same brand, same size, same class. It would not work either. I could not format the cards or anything. Pentax support suggested upgrading to latest firmware, which I did, but I still could not use these cards.

I have used Sandisk 4GB class 4 cards successfully. Have any other K20D owners had problems with large fast SD cards or Dane-elec in particular? I am reluctant to invest in more large fast cards if they won't work.

I use a 16gb class 10 Transcend among others in the K20D and never a problem. No idea why one brand is fine and another not but its not the size or class in this case.

My first stupid question is did you check the lock on the card? Next, can you read the card with your computer? If the computer reads it, try formatting it in the computer then putting it in the camera.

I've used Transend and Sandisk with no problems.

thanks for the replies, I can't wait to try another card. to answer Tom S. no the lock was not on, the card worked OK in my computer and in a Pentax RS1000.

In that case, there should be no reason why it won't work - unless you have a problem with the contacts in the camera or on the card.

What version of Firmware are you at? Several months ago, Pentax released a bunch of firmwares giving cameras better access to some SD cards. I never went beyond a class 6, 8Gb Transend in my K20d's.

Latest K20D Firmware Update : Software Downloads : PENTAX.

Great point Jeff. I had forgotten about the official reason for v1.04.
