Re: memory card error

The card error may be caused by several problems:
1. some minor electrical problem - turn the camera off, remove battery, wait several minutes, put back battery and turn camera on, see if it works. Proceed to next step to clean card contacts just in case.
2. Card not contacting with camera slot very well - remove card, use a cotton tipped stick with some ethyl alcohol (not alcohol drinks!) or isopropyl alcohol (many cleaning solutions like magnetic head cleaners) to thoroughly clean each contact. Avoid spilling and leaving drops on the card. Dry the card well before inserting it again.
3. Card became defective: try card on another camera and/or card reader (many laptops have a SD card reader built in). If not working, discard card and sorry for your loss. If card works somehow, download everything useful and try to format it to see if it's working OK. Try to fill it up with some files and copy them back too some temp folder just to see if it's writeable and readable.

!!! In case the card seems to work, but your pictures are not there (card is empty or contains garbage) you can try to use TestDisk ( - it's the best picture undelete program and it's free. Of course you should try to recover your data BEFORE testing the card with formatting, writing etc.

!!! Always format your card in the camera after tinkering with it on a computer! Camera format is not the same as format from the PC.

Hope this helps.

Error message: communication error

I use a USB cable and never see a communication error

Camera says "communication error" when trying to transfer images to computer. Why?

Try NOT connecting your camera to your computer.

The best way to transfer pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo management program such as Picasa.

I took pictures on my camera without a memory card can i still download my pictures

I'm glad to provide the steps to transfer images from Internal Memory of the Camera. When the camera does not have a memory card in it, the images are saved by default to the camera's internal memory, which holds different amounts of images based on how many megapixels are built into the internal memory and what image quality and compression are selected in the camera's menu. Once a memory\picture card is inserted in the camera, the camera then saves the photos to the memory\picture card and ignores the internal memory.

There are two ways to transfer the images from the internal memory.

  • To transfer photos to a computer from the internal memory using the USB cable, first remove the memory card from the camera. Then, when the camera is connected, the computer and software will only see what is in the internal memory and transfer those photos or videos. During the transfer process, the computer makes copies of the photos and videos-the original images remain in the internal memory. After the transfer is complete and the camera is safely disconnected from the computer, the contents of the internal memory can be deleted by using the MEMORY FORMAT function in the SETUP menu in the camera's menus.

  • The other way to transfer photos from the internal memory is to transfer them to the memory\picture card using the BACKUP function in the SETUP menu. If there is no memory\picture card in the camera, the BACKUP function is grayed-out. During BACKUP, copies of the images are transferred to the memory\picture card-the original images remain in the internal memory. After the BACKUP is complete, the internal memory can be cleared by removing the memory\picture card and formatting the internal memory using the MEMORY FORMAT function in the SETUP menu in the camera's menus.

Note: When the camera is connected to a computer using the USB cable with a memory\picture card in the memory\picture card slot, the computer will only see the contents of the memory\picture card.

Thanks for understanding. Please let me know if you require any additional help.

I connected my cable to transfer pictures from my canon 100 ixus but it showed connection error. What does it means?

Troubleshooting the camera displaying Communication Error when connected to the computer via USB. If the camera displays "Communication Error," when trying to download images the main cause for this error is that there are more than 1000 images stored on the memory card. It is recommended if there are more than 1000 images on the memory card, that you use a card reader to acquire the images, or to delete images off of the memory so that there are less than 1000 images to download from the memory card.
If this is not the case, there are not 1000 or more images on the memory card, try reconnecting the camera to abnother port on the computer, try another cable or another computer. This error can also display when connecting to a direct print printer. Please check with the printer manufacturer for more information on this error.

Transfer to memory stick

You should be able to go into the menu for the camera, and select memory card for photo storage. You should also be able to preview the images with the memory card in the camera, and have the ability to copy the pictures from internal memory to the memory card.

Computer freezes up while trying to transfer images

Hi, The only reason your apps freezes is if it is having a hard time communicating with the camera and more often than not it is the memory of the camera that causes this. A couple of things you can try: 1. Rather than direct connection camera to PC, use a memory card reader. Remove the camera memory and use the reader to access/transfer the files; 2. It may be time to reformat the memory card itself which can be done by the PC through the card reader or the Format command in your camera; 3. retrieve files from the camera memory using a file recovery program such as "GetDataBack for FAT" and after all pictures/data/files have been recovered, do 2 above; 4. Try a different memory card (not necessarily same capacity) to check whether it is the memory or the camera itself; and/or 5. Reset you camera (powering off and removing the battery). Good luck and kind regards.

Error message: card cover open..yeah right

Hmmm, I'm thinkin' if there's no memory card in camera, there are NO memories, aka formerly known as photos. Unless there is some sort of an internal memory, but me thinks not. As for error message, might be because....card fell out while an image was being captured.

Bug in the Optio S40?

Somewhere I read to be careful using cardreaders, using your memory card in different camera's and managing your card via the computer. Appearantly all of these can corrupt your card. The advice is to hook your camera directly up to your computer to transfer images and perhaps it is wise to erase images through the camera's menu instead of via the transfer program of the computer. Try formatting the card using the camera's menu and see if the problem persists.
