Query: Not Reliable AT ALL !!!

Bought a 2GB Transcend CF card from [...] when I bought my Canon 40D SLR. After one round of use, non of my PC at home can recognize this CF card anymore. I lost all the pictures I took from that memory. I called Transcend company and they send me a replacement. This time is a different story. The upload time to my PC is so SLOW (SCANDISK took only 1/4 of the time to upload all my pictures).Worst is some of the pictures uploaded to my PC were damage!!!I WILL NOT touch this memory card for the rest of my life.Go with SANDISK, at least the pictures you took are save...
