Probably due to a power outage, I suddenly lost access to a connected USB HDD yesterday. According to parted, I get the message “unknown partition table,” and gdisk says the GPT is corrupted. Using testdisk, I was able to copy the files to another drive and restore the partition table and mount the HDD.
Is it possible that the partition table was damaged by the power outage, or does this point to a different problem? Can I safely store data on such an HDD again, or should I replace it?


I see, they’re solving the issue other way around then by using raid. Didn’t know smartmontools work with a database, so it works kind of like an antivirus in a way. Interesting.
By the way, again it’s just my experience but I want to ask this. Have you noticed faulty disks are more common in NVMe SSDs than HDDs or I happen to noticed that because it’s common in cheaper options and more expensive ones are actually worth the price?
60 40 hard disks. Tho many SSDs just die Vs Hard disks which often die a slow death.
