And there's bad 1.02.05 news here after a few days on my new Lexar 633x 128GB cards. :-(
My new cards arrived on Monday June 15th and I formatted them in the X2. I examined the content of both cards after my first drive on Monday and everything seemed to be OK.
Last night during my pre-bedtime glance-into-the-garage-to-make-sure-everything-is-OK check, I noticed a glow coming from the X2 which was the infamous "frozen logo". I cursed and unplugged the X2's power cord and went to bed, leaving the investigation for this morning.
My wife had the X2 car all day yesterday. I asked her if she recalled the X2 display being on abnormally, and she had no recollection, but it's possible she might not have paid any attention to that since it is pretty much exclusively my gadget.
I examined the contents of both cards this morning. The front card has all of the expected content, up until the point when my wife returned to the car yesterday after 4.5 hours of parking. The last chronological video file (in any directory) on the card was a parking mode file of my wife getting into the car. She had possession of the car for another 8 hours but no other front card content was recorded after that last transition from parking mode to drive mode.
The rear card has big gaps in the record for both parking and drive modes. All of the expected content was there for the first day. Only partial drive content is present after that, and only a single drive file from yesterday on what was more than a 2-minute drive. There is zero parking content from yesterday during the same 4.5 hour timeframe captured by the front card.
Also, this morning I notice a file on the rear card root directory named _disk_id.pod with a timestamp from Monday night probably when I pulled the power plug prior to removing both cards to check the results of the first day. I don't recall seeing that file on Monday night. It would be odd for me to have missed that, since I was verifying proper operation of new cards.
So there are at least two issues here -- transition from parking to drive, and front vs. rear.
Both cards are still sitting on my desk and are available for further troubleshooting. Using Windows 7, I was able to successfully write a small .txt file to the root directory of each card just to verify that they hadn't flipped to read-only.
