SDHC Card failure - physical

On Friday I had to download some images so I extracted the 32 GB SDHC card from my camera and flicked the lock/unlock tab into the 'locked' position as I always do before pushing it into the computer slot. As I did so the small plastic tab broke off and vanished into the distance and the plastic next to where it had been sheared and stuck out at an angle. So, whilst I could download the images I was left with a useless card because the camera thinks it is locked.

 

Fortunately I'd bought it locally and was supplied with a replacement yesterday (moral: support your local dealer). But its worth bearing in mind that card failure may not be purely electronic.......

I was talking to someone the other day who never wipes their memory cards, they use them like film and just get a new one when it's used up! Expensive way to store your images.

 

It is very doable with older camera's I used to do that with my M8/M8.2 with Sandisk 8GB Extreme (45MB/s) cards, they were cheap and fit more then 900 pictures (DNG) from the M8. If I remember correctly.

 

With the current M it's not doable or with the M9 neither... not for my budget at least...

These low-cost flimsy pieces of plastic and plating are more vulnerable than we tend to think. I have always handled them with great care, knowing just how many irreplaceable pictures they can contain.

 

Unless I have a compelling case to do so, I avoid using that little mechanical sliding lock for the reason you have described. It happened to me once, on an old low-capacity card, so it was little loss to 'bin' it. But a modern high capacity card is a different matter.

Same here.

 

I split a card one time, but have no idea how. That is one reason I like the USB on the camera. The more you mess with the card, the more likely there will be a problem.

I broke a plastic tab in places unknown. Tab missing, card split up one side. It was a cheapo from Frys and no important images were lost.

 

And that is why I prefer the USB port for download. Can`t bend a pin, can`t shear a tab. If a port breaks, I can still pull a card. The port can be replaced at next service call. If I shorten the battery life, I will buy a new battery. No service required.

Well the price of the cards are dramatically going down in price at the moment, as new UHS2 speed cards are coming out now.

All this means is that they have been given a new minimum requirement of read and write speeds.

 

i managed to find a 64gb class 10 uhs1 for £30, Few years ago i paid that for 1Gb!!
