I've searched and tried a lot of stuff but still can't get it to work.
I was able to use my seagate HDD properly last week but now it doesn't mount. I tried plugging it to a PC & another mac, it works fine on both. The reasons could be
- Updating OS to macOS Sierra
- Not ejecting properly
- Installed sims4 with wineskin
Things I have tried.
- From disk utility clicking on mount & first aid.
- From terminal writing:
diskutil mount disk2s1
&diskutil mount readOnly disk2s1
both resulted with thisVolume on disk2s1 failed to mount If the volume is damaged, try the "readOnly" option
- From terminal writing:
diskutil repairDisk disk2s1
&diskutil repairVolume disk2s1
. - Restarted mac in normal mode & safe mode.
/private/var/log/install.log
from here found some logs but don't know what to do with them.- Switch USB ports & retry.
- A couple of other things.
