Hey, I've had some issues shooting timelapse sequences lately. After the sequence was ready, either by stopping with the play-button or setting an amount of frames in the intervalometer submenu and let it finish, I shut the camera down. Sometimes (way too often) when I start the camera again it says "could not read card". At first I obviously thought I turned the camera off to early or took the SDcard out while it was still writing (led blinking). But even when I took care that this is not the case the error happens. Some information: -60D, Firmware 1.1.1. -ML 2015Mar29 Nightly, timelapse shot with Intervalometer and aettr always on (no post deflicker) -also tried an older build: 2014Oct08 -SanDisk 64GB Extreme SDcard (should be good enough I guess)
After the sequence was shot I can view all the images, everything is perfectly fine, it just starts after the camera was shut down once. When I mount the SDcard into my macbook it won't read it right away. A dialogue pops up informing me that something is corrupt and I need to click initialise and repair the partition with the OS X Disk Utility tool. After that everything is fine and the camera will work.
If you need me to give you some logs or something else, feel free.
