Hi.
I have an external USB HDD, which I wanted to use as a temporary
storage for my personal data while I clean up my local hdd. And while
moving files from local hdd to external hdd, it stopped responding. I
tried xfs_repair, but no luck.
Any insight on what has happened and what are my chances to restore
data? Here are my logs.
