Question about Canon Cameras

1 Answer

I have a Canon 7 D Camera. When I put the SanDisk Compact Flash card in my card reader into the computer, it will not open the photos. I have 3 camera cards and only 1 brings up the photos. These cards are less than 2 months old, have been formatted. We shoot raw. Up until now, they worked fine. Photos can be viewed in the camera and attaching the camera to the computer yields the same negative result. One odd thing is that I have two card readers and one (but not the others) was able to be opened using the 2nd card reader. As a test, I took them to CVS Pharmacy kiosk and same results there...what opened at home opened there and what I couldn't open wouldn't open there either. We used a new camera card today, took some photos and they opened fine on the computer. What I see on the computer when I try to open the files is 4 yellow folders. Three of them are "CRW" files 847 Canon, 848 Canon, 849 Canon. The 4th one says Canon MSC and there 3 CTG files in it. When I right click, the error message is "This file does not have a program associated with it for performing this action. Create an association in the Folders Options Control Panel" Another Fixya rep suggested using System Restore, but "no-go" as it stated there were no changes. We are nature photographers and have an order to fill for a gallery opening...Help please! Elaine

Hello elaine... just like larger discs, these SD discs sometimes go bad. A computer shop may be able to save the contents of the disc for you and transfer it to another. Joe

Thanks for choosing Fixya!

Is there some sort of adapter for a sandisk Ultra CompactFlash 4gb, that i can use to put picutres on my computer?


The device:
Belkiin Universal Media Card Reader
Can be connected to your computers USB port and will then allow you to move pictures from the compact flash card to your computer.
After you connect the device and insert the card you will see a short delay and near the bottom right corner of the screen a message will appear letting you know that windows is setting up the new device. Moments after this completes you will see a new window popup asking what you would like to do with the media card. From the list select move pictures to my computer with the Scanner And Camera Wizard. During the move it will remove the pictures from the card and give you more free space for pictures if you click the checkbox labeled Delete Original Pictures.

How to delete images off a sandisk extreme 3 2.0gb compact flash%3F


Pop your memory card into your card reader, wait about 15 secs and it will appear on your computer as a drive. Double click on this drive and you will see either a lot of icons corresponding to the photos on the card or a lot of thumbnail pictures of the photos. Again right click on the drive and click on select all on the popup box. When all the icons or thumbnails are highlighted left click on them and the click on delete on the next popup box. Whatever you do DON'T try to format the card with your computer. If you want to format a memory card for a camera always use the camera's format function to do so.

By the way, the photos can also be removed by using the delete function in your camera's menu display.

Make sure the record inhibit tab on the memory crd isn't activated. If it is you won't be able to delete anything.

My card won't work on my computer, what is wrong?


When you format the card, be sure to do it in the camera, as the camera firmware writes hidden files to the card.
When you insert the card into the card reader, be sure to set write-protect, so the contents cannot be corrupted.
I suspect what may have happened is that at some point there has been a conflict between files written to the card by the camera and the computer.

I have a Canon EOS 350D, Compact Flash card freezes my computer


Instead of connecting via the camera, just use a USB card reader and put the CF card in that.

Cannot retrieve photos from SanDisk Ultra 11 4GB


Card probably became corrupted. Try running a Memory Card Recovery Program. If that doesn't work take it to a place that'll do that type of thing professionally, a lot of electronics and computer stores do this for a small charge.

Internal memory??


Highly recommend that you consider using a card reader to download you pictures. You insert the camera's memory card into the reader, and then insert the reader into a USB port on your computer. The card then shows up as a hard drive so that you can simply copy/paste or drag your picture files onto your computer. Card readers are much more faster in downloading pics, do not require the use of your camera's batteries, and provide much more reliable downloading of the pictures (fewer errors). They're also VERY inexpensive these days. Here are some examples of CF card readers from Amazon:

http://www.amazon.com/s/qid=1223745821/ref=sr_st?keywords=cf+compact+flash+card+reader&rs=172282&page=1&rh=n%3A172282%2Ck%3Acf+compact+flash+card+reader&sort=price

Also, if the card has somehow become corrupted, take no more pics until you've recovered the photos. Take the card out of the camera. Here's some freeware photo recovery software that should be what you're looking for:
http://camerarepair.blogspot.com/2007/12/recovering-those-accidentally-lost.html

You will also need to use a card reader with this software. Finally AFTER you've recovered your photos, recommend formatting the card IN YOUR CAMERA to prevent this from happening again. Note that formatting will totally erase your card. Turn on the camera, press the menu button, select the tools menu. Go down to the selection that states your CF card's memory capacity and select it. Then follow the formatting prompts.

Help...it want my pictures!!


I have a SanDisk 8G SD card that worked in my camera, but my card reader would not read, so I could not put the on my computer. I put the SD card back in the camera and could still view all of my photos, so I ran a cable from my camera to the computer (one end of the cable was USB and the other end was something smaller that would fit into the port on my camera, I don't know what it is called). The computer was able to read all of my photos through my camera, so I downloaded everything through the camera to the computer.

Sony dsc s500 and a sandisk 4gb ultra II memory card problem


There is no way to do that since the internal memory is designed to only output to cards, not the other way around. Fortunately, this should not be a problem.

In general, the best way to transfer photos to your computer is to use a card reader - it provides a standard interface that the computer will recognize, it saves wear and tear on the camera, and it saves batteries.

I use Meritline.com for things like this because they are cheap and reliable, but please don't think there aren't hundreds of other places to get one from.

To help you, here is a link to the page at Meritline that lists card readers. Note that many have free shipping:

http://meritline.com/readers.html

This is a relatively cheap one with free shipping that will handle just about any card form factor except compact flash:

Good luck.
