I have an iMac which I have a 6TB WD External HDD attached to. I've never had a problem in the past with ejecting the HDD, then unplugging it (so that it's not running the disks for hours when I'm not using it). However, the last couple of days when I eject the HDD, when I go to unplug it, my iMac has a kernel panic and restarts (with the grey screen and the restart message in multiple languages). I've not only closed any program that was using the External HDD before ejecting it, but I've also gone so far as to open up Disk Utility, click on the main icon for the drive (even though the Named icon is greyed out, denoting it's been ejected, but is still connected), then clicked the eject button. But, to no avail.... Any ideas why something I've done the exact same way for the past 2 years is now causing a kernel panic / restart? Thanks, J.
