Lost partition table, can i trust the HDD again? (discuss.tchncs.de)

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?

Install smartmontools package for your distro, if it's not already installed. Then

Check your disk's name with sudo lsblk. After that, replace your_disk with your disk's name (sda, nvme0n1 etc.) in the command below.

sudo smartctl -x /dev/your_disk

If the results say PASSED, you're probably good. You can also pass the output to an LLM by the way. At least they are good at these kind of things.
