Earlier today a Time Machine backup was running on my MacBook Pro, which was plugged in and unattended. I forgot to activate Amphetamine, like I usually do, and came back to find the Time Machine hard drive disconnected and a Disk Not Ejected Properly message. The external drive reappeared within a few seconds of my Mac waking up. I am surprised that the drive got disconnected, especially so as the Mac was connected to the power adapter. I expect the OS to eject external drives before going to sleep.
I am concerned about the integrity of my Time Machine backup and of any damage the drive might have suffered. I was wondering what I should do to ensure that everything is in working order. I reckon that out of extreme precaution I could reformat the drive and run the fsck commands
sudo fsck_hfs -fS and/or
sudo fsck_hfs -fy -S (my knowledge with this is very limited!) to rule out any damage to the drive and start afresh with a new backup if all is well. Would this be overkill? Would love to hear suggestions from the community.
