CF Memory card problem

[Cashie]

:stuck: My problem is I bought a 2GB sandisk ultra II card from Amazon & every time I use it I get corrupted files, at first they are ok when I look at them on camera, then if I take a few more shots & look again it says corrupted, I have tried formating it Too.
Has anyone else had this problem ? and is there anything I can do to put it right.


Cheers

Persoonally I'd send the card back and get it replaced - I would not trust a card that has been giving problems.

I thought this too, but the trouble is I cant find the bloody receipt anywhere (what a pain) :C

If you got it through amazon you should be able to get the details on the order history on their website

Right Cheers Postcard, I will have a look.

For the future purchases - Sandisk up to 1 GB caused no problems for me while Pretec 1 GB had to be exchanged (similar errors) Personally I don't see any use of 2-8 GB cards with even RAW shooting

Well, there are two main reasons why I reckon a large (4GB card is better than 1GB).

A 1GB card can hold around 100 RAW images (even less if one shoots in RAW+JPG, as many do). That means swapping cards on most days out. And a card not in the camera is a lot easier to lose than one in the camera.

A 4GB card is roughly 3.5 times the cost of a 1GB card. So, if one often shoots up to 400 images in a day a 4GB card saves money.

Do you have the latest firmware in your camera, it might be that this is the problem! link below for Canon firware updates

I regularly use 4 and 8 gig cards with no problem at all, only had corrupted files with just one Lexar 1 gig card,

Paul,

something else to worry abut is the flood of fake Sandisk cards on the internet these days: an extremely quick search shows that Amazon might be as as affected as any other retailer:

http://www.amazon.com/Sandisk-Compactflash-SDCFB-2048-A10-Retail-Package/dp/B0000DD7PE

There's at least one "this is a fake" comment in the reviews on this page, a couple of "it doesn't work with my camera", reviews, and so on.

Here's another:

Some useful reading:

Unfortunately, it looks like they've reached this side of the pond too:

After using Sandisk CF and SD cards up to 1 GB without any problems, I decided to purchase a Lexar 133x 2GB CF and SD card, for a recent trip overseas.

Through the course of the week each card presented me with a few two many corrupted files, obviously images lost. With the Sandisk cards I'd only experienced this once or twice in the past 3 years.

So, I'm going to try the Lexars once more to see how they behave again, they've both been warned, last chance.

Ah but one day your card will crash-it happenes to most eventually and you will be cursing not spreading your days (or even weeks)photos between cards.
I back up each card at the end of each day (sometimes during the day if the opportunity arises).

Besides, I've never had a CF card fail. I have, however, lost one. The only way I can lose my 4GB card is if I lose the camera (which I'm likely to notice). I'm much more likely to lose a card when it's not in the camera - especially when I'm in a hurry to swap an empty card for a full one as the shot of a lifetime unfolds in front of me. That's when I'm likely to put the full card somewhere stupid in the excitement and lose/forget it.

And if CF cards do crash, then surely it's four times as likely that one (out of four) will crash than my single card doing so.

Thanks for the links Keith, they are very interesting. the firm the card came from through Amazon was called buyers first. (what a bloody joke) I dont think I'll be using Amazon again !

Cheers mate :C

Thanks Keith, very informative.
At this point I'm starting to tremble :eek!:
Can anybody give more details about the microswitch on Sandisk Extreme III 2/4/8 gig cards? Is it supposed to be on each and every card or only on those sold in the US?
I have two cards, both are working flawlessly, capacity is the same, but one seems to be a bit slower when my camera is writing down data (I feel I have to wait longer before the camera is ready after a burst of shots)
Thank you,
A worried Max
