Question: External hard drive isn't showing up on my Mac
I was listening to music in iTunes when iTunes decided to crash after I had clicked on a song to play. I waited a few minutes hoping that iTunes would return back to normal but it did not, so I then decided to go to activity monitor and force quit iTunes (which was unresponsive) and re-open it. When I clicked on the iTunes icon in my dock it just bounced up and down and never opened up. I went to activity monitor again and saw that it said iTunes was unresponsive. Next, I just decided that I would just restart my Mac, hoping that it would fix this issue. I then proceeded to open iTunes and see if it worked but this time a iTunes pop-up appeared stating that my library could not be found. All my music is stored on a Seagate Backup Plus Portable Drive which I have connected when I am listening to music so I went to check if the drive was showing on my desktop and it was not there nor was it in disk utility or finder; however it was making its normal fan noise and its light was on.
Since I could not see the drive, I wasn't able to eject it so I just decided to unplug it. When I unplugged the drive, the cautionary pop-up that states that you should eject your drive instead of unplugging it appeared which was weird since I couldn't find the drive anywhere else. I decided to plug it back in hoping perhaps it would show up and after a while it showed under storage and on the side panel in Finder. While my drive was plugged in I experienced that Finder was prone to crashing and it would take a long time to load applications (constant beach ball on screen) or they wouldn't open at all such as disk utility or to look at about this mac however if I unplugged the drive these would open up immediately.
I tried the drive on my sisters Mac and it took a few minutes but it appeared on her desktop. I was able to access the content within however it was really slow to open. All my files and folders seemed to be in place and I was able to access them but once again it was extremely slow to navigate and open them and the beach ball would frequently appear. I decided to move around about 6-7 pictures and it took around 20-25 minutes to transfer these. If I were to move larger files such as music and movies it would take a ridiculously long time. I'm not sure why I'm not able to access the files on my Mac.
I'm not sure where to go from here. I haven't plugged in my drive into a device in around 2 days because I've heard that can further damage and worsen the condition of the drive. So my questions are:
- Why is the external so slow and why is Finder the only application that crashes?
- Why can I see the external and its contents on my sisters Mac and not mine?
- What are some ways that I can transfer/backup the important files from the external?
I have a MacBook Pro 2017.
