I put the disk in a USB3 box and bought a new one. I know that SSD disks loose memory with time. I wonder how this works and I thought that maybe if I reformat the disk, I will be able to use it again.
I don't recall if you mentioned the model of SSD you have. I wonder if it has SMART capability.
What is the output of
sudo smartctl --all /dev/sdX
where X is the device identifier
I put the disk in a USB3.1 box. It says: smartctl 7.0 2019-03-31 r4903 [x86_64-linux-5.2.13-200.fc30.x86_64] (local build) Copyright (C) 2002-18, Bruce Allen, Christian Franke, www.smartmontools.org /dev/sda: USB to NVMe bridge [please try '-d sntjmicron' and report result to: smartmontools-support@listi.jpberlin.de] Please specify device type with the -d option. Use smartctl -h to get a usage summary
The other new one gives much more information. I should probably try when plugged directly to the mother card.
