SD memory card problem with K-5II

I bought a Lexar professional SDHC 32GB 400x speed memory card earlier on this year and generally it has been fine.

BUT ever since I bought it I have had the occasional picture that is corrupted...










Has anyone else had this problem? Is this a problem with my camera writing to the card or the card itself? Any thoughts would be welcome.

Is it the only card so affected? If all other cards are fine then I would ditch this one.
Best regards, John

Yes John, I have not had this issue with any other card. And I have checked that I am on the latest firmware with the K-5II (1.07).

Thanks.

It's not worth using the card then. Many of them have limited 5 or even 10 year guarantees, so I would check the manufacturer's website for procedure and return the card for replacement.

I Only ever buy Sandisk cards, & then I only buy the fastest cards I can lay my hands on...usually 95Mb/sec variety. I have had no failures or issues with these.
They are cheaper now from MyMemory than they were. 25 for a 64 or 32mb card...
I have heard (on this forum) that there have also been issues with Sony & Samsung SD cards too.
I sure you will get some more recommendations shortly...

Hi, Whatever you buy (and there is some advice from Ricoh around link if it fails then stop using it as it won't get any more reliable. You've perhaps just been unlucky as most cards last well.

I always format rather than delete. I understand this reduces the number of writes before failure as all flash memory does eventually. Accidental removal while camera powered or while transferring files in a reader can contribute to corruptions.

I'd also be careful where you store cards when not in camera. I'm concious that I often have other gadgets in my bag when travelling.

Wow - thanks for the link Bill. It appears that this Lexar card has not been tested for use with Pentax K-5II. Looks like, as has been suggested, that sticking to Sandisk might be a good idea.

I bought this from My memory because I also bought a Lexar memory card reader for my computer so I didn't need to use the cable from the camera. But I now see that looking at their website, they will only take returns for 6 months from date of purchase for faulty goods. That doesn't sound so good.

Looks like I will need to contact Lexar. Thanks everyone for your input.

I've only ever had two cards fail on me, both 16 GB PNYs bought from Currys. I only use Sandisk now, always 16GB. Its not that I don't trust the larger capacity cards its just too much of a risk having so many eggs in one basket when shooting loads of pictures. .
Even with the 24meg sensor K3 I get around 300 shots per card and the K3 has two cards so that gives me up to 600 shots without reloading.
Card failures can be due to a number of reasons, perhaps the most common being the one mentioned above, inserting or removing cards with the camera switched on.
I don't think I ever had a Lexar memory card.

Well just to close this off.

I contacted "My Memory" where I bought the card and asked what I should do bearing in mind it was 11 and a half months since I bought it. They told me that it should be fine with my camera K-5II and asked me to send it back for full refund - which has now happened.

So I am a happy customer.

Thanks for everyone's comments. I probably won't be buying Lexar memory cards again.
