well CF/SD cards are pretty durable if u r talking abt environmental hazards
corruption of data usually is human error if I am not wrong. some cams have no protection if the CF door suddenly opens or battery runs out when deleting images. that causes file corruption. (might also happen if u forcefully remove the CF card while writing/deleting files from the CF card)
wow u must really work your cards hard .. do u take them in and out of the camera often?
I dun and so far my cards are all doing fine.. *touchwood and i hope they stay fine..
but your experience is putting me off buying cards 2nd hand..
Personally, I never had a CF die on me. I have 2 that are > 3 years. But then again I am not a strong user. Quite surprised at the bad experiences people had with CF. Wonder if there are similar occurences with the SD format... this I am now using quite extensively.
Yes it can happen. In one case lucky not a paid job, while reviewing a CHK error was shown on camera and it hung. Rebooted the camera, guess what 2 files went missing ; the one I was looking at and another 2 or 3 files back from the last one. San Disk Ultra II.
Maybe it time to retire current cards and get in new ones - these are around 2 years old and have been worked hard my guess is that they could have gone around 20,000 frames.
