gary_anthes Posted July 30, 2005 Share Posted July 30, 2005 I went out this AM with my Canon 20D loaded with a SanDisk Ultra II, 1GB card. The card was about 75% full. After shooting for a while I got a "CF Full" message and, not surprisingly, the camera quit working. I loaded another card and went on. When I got home I was able to download images from the second card OK. But none of the new images on the first card could be read, either by my PC or by the camera. Two new folders of the format "nnnCANON" had been created but seemed to be empty. The photos from previous day's work were there just fine. So I put the card back into the camera, and now it says the card is NOT full and I am able to take pictures and download them normally. But the photos I took this AM are plain gone (or not retreivable). What I'd really like to know of course, is whether the card or the camera is to blame. Any ideas? Also, is there reliability data available for the various brands of CF cards? Many thanks. Link to comment Share on other sites More sharing options...
kbreak Posted July 30, 2005 Share Posted July 30, 2005 Did your SanDisk come with a RescuePro CD like mine did? I used mine once and it worked perfect. Link to comment Share on other sites More sharing options...
gary_anthes Posted July 30, 2005 Author Share Posted July 30, 2005 No, I don't have any of that rescue software, but this seems like a good time to buy one. Link to comment Share on other sites More sharing options...
peter_nelson1 Posted July 30, 2005 Share Posted July 30, 2005 Yikes! I just bought a new SanDisk Ultra II 1G for my 20D yesterday for an important model shoot next week! This IS scary!! Was this the first time the card was used? If not, what was it used for, before? Was if formatted before this use? Had you ever filled the card up this far, before?

gary_anthes Posted July 31, 2005 Author Share Posted July 31, 2005 Peter, it was not the first use, and it was formatted in the camera at the beginning. I have several cards and I can't be sure if this particular one ever filled up before. I'm going to retire it and watch what happens with the others. I will also, when I'm out in the field, periodicaly dial back through several photos to ensure they are being written. Link to comment Share on other sites More sharing options...
EricM Posted July 31, 2005 Share Posted July 31, 2005 Canon has trouble with some larger cards. Lexar just relased an updated version of their pro 80x to deal with this. Maybe ask on the Canon forum? Link to comment Share on other sites More sharing options...
gary_berg Posted July 31, 2005 Share Posted July 31, 2005 Are you sure you turned off the camera and waited for the electronics to turn off? Link to comment Share on other sites More sharing options...
