Hi,
Today I noticed my external Samsung HDD is very slow suddenly.
Itā€™s also impossible to eject it from my Mac (I have to turn off my Mac every time I want to eject it).
So I have run First Aid on it in Disk Utility. Hereā€™s the result:

What does it mean?
Is this disk unfixable? Is recycling it the only option?
Because it actually works, but painfully slow.
May formatting it fix it?
I have most important data from this HDD backed up elsewhere.

I appreciate any help!

Sounds like the HDD is on its last legs. I would try to copy any data that is not backed up and then recycle as electronic waste.

What I'd do:
1. back up the drive
2. reformat the drive
3. run disk utility's "first aid" on the reformatted drive
4. do you get "a good report" now?
5. if so, I'd re-run first aid 5 times in a row
6. if I got a good report every time, I'd continue to use the drive, but keep it backed up!

In case this helps anyone, I had a corrupted thumb drive and the macOS ā€œDisk Utilityā€ was unable either fix or even erase this drive. I wasn't try to recover anything from the drive, but just reformat/repartition it so I could use it again.

I ended up having to reformat it from the Terminal command at described in ā€œSolution 2. Repair the USB Drive With Terminal on Macā€ outlined in https://www.cleverfiles.com/howto/fix-corrupted-usb-flash-drive-on-mac.html

So when worst comes to worst, Terminalā€™s diskutil can help. Be warned, though, as you probably can very easily wipe the wrong drive if you are not extremely careful!!! Use with extreme caution.
