I have a 2015 Macbook Air running High Sierra 10.13.6. Yesterday I successfully backed up through Time Machine to my “My Passport”. But when I closed my laptop, the light on the drive was still blinking, and I thoughtlessly pulled the USB out.
Today, it still flashes, but it won’t back up at all. There was incomplete backup document in the drive folder, so I tried deleting it. But that didn’t help; maybe made things worse actually
I don’t know how to fix this. I see others having problems with High Sierra and this brand of external drive, but mine was working yesterday.
Any suggestions
