I bought a new 2GB CompactFlash II card so I could take lots of National Day Parade photos using my dad's Nikon D70 SLR camera. I thought it would be good to get a high-speed card so that large files could be saved quickly, which would make it ideal for taking fast-moving objects and fireworks.
In summary, NDP 2007 rocked, and I took over 500 photographs :) However, when it came to downloading them into my computer, I lost several photos as they seemed to be corrupted.
The thing is, the photos looked fine when previewed on the camera itself. But my old SanDisk 6-in-1 card reader failed to recognise the CompactFlash II card when connected to my Mac. Another card reader which I purchased last year, just prior to SXSW in March, also couldn't read the CompactFlash II card.
My last hope was a relatively new PC we purchased last year, which has a built-in card reader. This time, the photos in the CompactFlash II card could be viewed. Well, most of them. I lost the first few shots and the very last shot. Even their file names looked truncated. What I did next was transfer the photos from this CompactFlash II card, into a 2GB SD card. Using this second card, I transferred all the photos into my Mac.
During this second transfer, I lost another 2 photos. One photo looked like its top half got cut and pasted to the bottom. Another photo simply couldn't be viewed at all.
It was getting worrying, like soldiers moving from location to location in a battle and a few getting killed at each point. And these are relatively new memory cards! Both were high-speed. Do any of you know if high-speed cards cause more problems? Cos if so, I'm switching back to normal speed cards.
