Hello WYooy,
Thank you for your reply.
Your Intel® SSD Pro 5400s Series (256GB, 2.5in SATA 6Gb/s, 16nm, TLC) is a Dell* drive and has their firmware and modifications.
For a warranty replacement, we advise you contact Dell* since as you mentioned the SSD came included with your PC.
The behavior of the Intel® Solid State Drive Toolbox (Intel® SSD Toolbox) is expected since as mentioned this is a Dell* SSD that contains a different firmware and could have been modified by the OEM (original equipment manufacturer) to fit their needs.
We will be looking forward to your reply in case you need further assistance.
Best regards,
Josh B.
