I've had an external HD for many years now, and it has been partitioned with a windows compatible drive and a mac only compatible drive where all the backups are stored. Whenever I need to eject the drives, the Windows drive disappears immediately, whereas the Mac on takes ages and can never be ejected unless I click on the Force Eject button. This has been quite recent - over the past month or two where the only way to eject the Mac drive is to do a force eject. No idea how this problem came about or what I could do to solve it. My concern is that it maybe corrupting some of the data that is on the drive by force ejecting it, but otherwise I haven't any other choice.
