EOS 500d Camera can't download images form SD card

Sounds like you have corrupted files even though the pictures can be viewed thru the camera, your operating system can't read it.

Can you see the folder and files on your vista or you can't see the media all together?

Have you tried downloading the images from the camera itself?

If the images were not that important to you then you can just reformat the flash card otherwise you will need a photo recovery programs.

If your current Sd card is 4 Gig or larger and your old one in the 400D was a 2 Gig or smaller card it is a problem with your card reader not windows.
4 gig and larger SD or HCSD ( High capacity SD) card can not be read by older SD card readers. Your simply need to get a newwer card reader and all with be fine agian. if it was the same size card you have anouther problem all together.

hi duddy!
Why not try any best or latest version of meory card recovery tool. You must find recovery application to recovery corrupted SD card. If your SD EOS 500D is not supporting downlaoding from SD card then i think there is a problem in card. In this situaion you need card recovery application to recover corrupted, images or lost imges from SD card.

Hi,
I have an EOS 500D - EOS Utility used to read the SD card fine when I was running Windows XP, but now that I have upgraded to Windows 7 I get an error "Cannot write to selected folder, choose another folder". The problem seems to be Windows 7 - I have downloaded updates to EOS Utility, but it makes no difference. I can access the Memory card as an extrernal drive and copy and paste the images, but EOS utility refuses to transfer them. Come on Canon - sort it out!
