I buy a memorycard sandisk 4 gb, i have a photocamera canon ixus digital 750. i insert memory card into my camera and than it show me : "errore memory card, scheda bloccata ". what must i do ? thank you

According to the specs on Canon's web site, the IXUS 700 works with SD cards, not SDHC cards. SD cards are limited to 2GB in size (there are rare 4GB SD cards, but they tend not to work in SD devices).

Of course, it's your call as to how definitive any manufacturer's web site touting their product might be.

How big is its capacity ? Some device can only support memory card at certain maximum capacity, if you inserted card with higher capacity it wouldn't able to read it and it would say "card error".
Try to insert another card with lower capacity. i.e. if you have got "card error" notification for inserting 4 Gb memory card, try to insert 2 Gb card

Hope this help, and if you think its helpful RATE please.

maybe you insert more capacity of support th memory card 16 gb only trye with 16 gb . good luck Anderson From Dominican Republic. Visit us to be uon the sky with our sunny days.

Having gone over a month with no response, I assume it was just a matter of SD versus SDHC cards.

Yes. The IXUS 60 was designed to work with SD cards. Cards larger than 2GB are actually SDHC (the HC stands for High Capacity) and will not work in this camera.

Hi,

A 4 gb memory card is beyond the capacity of your Cannon A540. It is too large. I would stick with a 1 gb card in that camera.

Hi,
I'm sorry to tell that PowerShot SD 630 does not support SDHC cards over 2 gig.
If you want the camera to take a card over 2 gig then you are stuck standard SD cards.
The other camera does support the card because it's a higher model.


Regards.

I assume that you know that there is a tiny tiny on-off switch on the edge of each SD card. If they are locked in the off position....

the a 620 only goes up to 2 gb no higher

Check in the Manual that the camera can accept 2Gb.
If it say it can then return the card for replacement.
