p.1 #1 · p.1 #1 · CF card errors with USB 3.0, okay with USB 2.0 | |
Hi-
I recently ran into some issues with my compact flash cards, and a couple of USB 3.0 card readers that I have.
I have a few SanDisk 32GB Extreme Pro CF cards (UDMA 7, 160MB/s) that I used to shoot a couple of events. When I used a USB 3.0 card reader to copy the files to my PC, all of the files were damaged in a similar way as shown in the sample image. I thought it was the cheap card that I was using (Transcend TS-RDF8K), so I picked up a 2nd one. I used a Lexar multi card reader LRW025U to try copying the files again to my PC. I ended up with the same results. I tried to copy the files to two different hard drives, as well as the SSD drive that I have my OS on. Same results.
On a whim, I used an older USB 2.0 card reader to see if that would yield different results. I tried it with 10 .cr2 files and all of them copied without errors. I tried another 10, and they copied okay as well. It took a long time, but I was able to copy all of my files to the PC with no errors.
I wanted to see if anyone else had experienced anything like this, and what you did to resolve it. I formatted the CF cards in two different camera bodies, so I'm not sure if that could be part of the problem or not. I have a Canon 5DMKIII and a Canon 1DMKIV both with the latest firmware.
Thanks for reading.
Here is a link to a couple of sample images copied to the PC using the USB 3.0 card reader.
