Hi my first post as i'm new. Can't help but throw in my opinion here. Having had to recover data in the past and play with various external devices both on Linux and windows I've some experience of these issues. Only once a file system corrupted -i put it down to dodgy hardware(a usb drive). When ejecting/unmounting correctly i believe it sets a flag to identify it as ok. Often if just yanked out and plugging into a different OS it will be seen as locked/broken and not allow access. Cant say I've tried this recently as I'm all single OS these days. Hope thats of any use.
