(Related thread: Loss of Data)
Got this USB2.0 card reader that I've been using for about a year already. Never had any problems. And I've been using the old 1.0GB IBM Microdrive, SanDisk and 512MB Kingston (Orange).
Recently, I got myself another Kingston (Orange) 1024MB and horror of horrors, I lost data! Everything seemed to check out fine. I thought maybe it was because I swapped cards too fast or something (I did no different in the past with the other cards, no probs), but when I stuck the CF card in, at first it wasn't detected. Then I rebooted, and it reported NO DATA!
Then, practically exactly the same thing happened with my new Kingston SD 512MB cards. After I plugged in into the reader, same problems, and the camera also reported no pics.
Took out my cranky old USB1.0 reader as a desperate measure and it read the SD card perfectly! Too bad I formatted my CF cards before I thought about using the old (and verryyy slooowwww) reader.
So, I'm now wondering: Is it my card-reader problem?
Or is Kingston a problemmatic brand (and that's why they are so cheap and often given away as gifts-with-purchase?).
The reason why I bought a new card reader was also because the orange Kingston CFs refused to be read in the old one. Some Canon cameras (specifically the PowerShot S60) refuses to even recognise them, format also cannot.
