Greetings, I was performing a partition shring operation during that HDM stopped to responding, I only had chance to Debug or Close, so I chosen close. Now there were file system errors, ie. some directories were corrupt so chkdsk converted their files to FOUND000 folder. I'm afraid to run the operation under Windows again since I don't know if that's a HDM bug or something wrong with my HW, the resized volume was an external HD (USB2). Anyway, if there was anything wrong with the hardware, HDM should abort safely, preserving all original content, so I assume this is a bug.
