Same happened to me today, pictures on Eye-Fi Pro X2 card became corrupt when using third-party card reader. Spoke with customer service who confirmed the known issue, especially with UDMA card readers.
In my case, while shooting on location today with a single-slot-SD camera, RAW+jpg pictures recorded ok on the Eye-Fi card, and .jpgs transferred to iPad wireless during the shoot. (on prior shoots I would record RAW on a separate CF card using dual CF/SD slots, and downloaded RAW files to computer with no issues). When attempting to transfer RAW files from Eye-Fi card to Mac Pro on OSX 10.6.8 via third-party Hama card reader (I didn't have the Eye-Fi usb reader available) the card did not mount and OSX error message "The disk you inserted was not readable by this computer" came up, asking to initialize the card, and the card stayed un-readeable and would not mount. I put the Eye-Fi card back in camera and all images were still there.
I switched to a Lexar Pro UDMA CompactFlash SD usb 2 reader and the drive mounted ok. However, when navigating to the image folder, OSX crashed with "You need to restart your computer" (kernel panic descending black screen of death) message, and was forced to force-restart. Did the same thing a second time with same results.
I tried another Mac Pro in the office using the Lexar, and the card mounted ok, but folders contained zero byte alias files and seemingly corrupted data with weird random file names. No image files were present. I put the card back in camera and this time it said "File does not contain image data," and no images came up for review.
At this point I called an Eye-Fi customer service agent, who was very friendly and worked through the issue. She confirmed the only card reader officially supported by Eye-Fi is the reader supplied with the card, and with any third-party card reader you run risk of corruption issues. She offered to email a list of supported image rescue software links I could follow up with to try and retrieve images off the card. (this email hasn't come as of several hours later).
I used Image Rescue 4 and was thankfully able to retrieve all images from today's shoot.
It leads me to the conclusion that while this is a fantastic product concept, the possibility of file corruption makes it unacceptable for professional usage at this time. Perhaps using Eye-Fi hardware only, other users may have had continued success with transfers and no corruption issues. I havn't seen or found anything thus far on the Eye-Fi site or instructions which specifically warns to not use third-party readers for downloading. This would be helpful.
A quick forum search shows other corruption issues as well, so there seems to be an issue with more then just third-party readers.
Please fix. Thanks!
