I was copying media file from my Skhynix SC308 SATA 256GB which I used as a storage drive,
The drive was connected via external USB enclosure. It eventually went off when I was copying a media file from the drive to my PC running Debian 10.
I have taken the below steps to see if it would work.
I tried another USB port, it didn't come up,
I plugged it into a Windows OS, it didn't come up,
I used it as my laptop primary drive, it wasn't detected in the BIOS,
I replaced the SSD with a spare HDD, HDD worked fine, this shows that problem is neither from external USB enclosure nor the OS but the SSD.
Does anyone have clue on how to get it working again.
