UPDATE [SOLVED]: searching for this problem I stumbled into this thread: https://discussions.apple.com/thread/7045334?start=15&tstart.... . as I'm running windows 10 on a mac using bootcamp, it only took me to rename c:/windows/system32/drivers/AppleHFS.sys to something else, reboot and get truecrypt running as before. only side effect until now: I can't see the mac partition contents in windows.
same issue here. truecrypt was running well with windows 10 but then started showing this warning. i looked in the windows events logs but found no clues.
It displays
and the Computer Manager displays the drive with the RAW type.- Even though the filesystem is intact (tested on another Windows 8.1 computer) and
- chkdsk showing NO errors (yes that's right: it even shows the filesystem as being NTFS).
Aside from that my UI/UX experience with Windows 10 is great and I'm really happy. The above thing is a bummer though.
