This Samsung SSD had 3 attempts to load an operating system that was successful but my older fujitsu laptop does not recognize the drive,The data was transferred as crystal disk info sees the loaded data.Took to a specialist computer shop and says my bios is too old and does not support GPT/UEFI.So as you can see with the crystal disk info data,There are very low hours of run time and the only data should be the 3 attempts of loading a OS to the drive.There Some surface scratches to the case of this drive was from removing a caddy a few times.The drive was tested on a newer system and it recognized it at the computer shop,So the drive is good but you need a newer bios with GPT/UEFI.There is red pematex caulk in the rear screw heads for security so I would know if the computer shop opened this drive.Selling for what I paid for it a few years ago.
