Was this User Error, Camera Error or Card Error? The story. Went to shoot a lovely assignment on a violin maker today, the last in South Africa.Great ligthing. Natural. D2H, Sandisk Extreme 2GB card, formatted. Took 130 shots, looked great on the screen. Back at the office, pull 256K Canon card out of Mac CF card reader, forgetting to do the proper card eject procedure. Put in D2H Sandisk Extreme. Still see Canon icon on desktop. Thinks "Damn, forgot eject procedure" Pull out D2H Sandisk, reinsert.. Great, icon appears on desktop.. Open file...says zero items, no nothing (but it's used 1GB of space) Put card in D2h, says No images in Folder.... Flat panic, near suicidal, near tears. Rush home in the car, find Rescue software and run it. Whew, most of the pictures are saved, but about 10 have multitechnicolor stripes through them, corrupted, in no particular order. But I've got most of them. So what was the problem ? I've pulled out cards before without a problem, forgetting to eject properly. I definitely switch the D2H off before removing the card. My error ? Should I be worried about the card's reliability. Or the camera? Please advise if this has happened to you or if you have a likely explanation. Much appreciated in advance.
