External disk not mounting - after Mac freezing in a disk First aid operation
Dear All,
Here is the story...
I have a seagate disk for my backup. It was full and it seems that the Time Machine / backing up had problem to delete old backup.
I wanted to clean some file through Finder. But it took an eternity... without result.
Wondering if there was an issue on my disk I run disk utility / first aid.
Running for while ... Then my mac freeze. I stopped it (off button)
Then restarting the external disk is not mounting anymore.
Still appearing in disk utility.
I try again First aid but it's running for hours without success.
No result either with Paragon !
I try through the terminal some diskutil/verify
Chriss-MacBook-Pro:~ Chmar$ diskutil verifyDisk disk2

THEN:
Chriss-MacBook-Pro:~ Chmar$ sudo fsck_hfs -f /dev/disk2
** /dev/rdisk2
Msg: computer can nt read disk. I click initialise , First aid open. Unmounted. Try to mount nothing.
And the result is here...
