This is for backup use with power-on only once or twice a month, so usage time is short. There is also some slight yellowing. I got frustrated because the HDD replacement didn't go well without initialization, but I was able to initialize it with the original HDD. I only use it for backups, and it's difficult. Others seem easy, so I'll buy from another company. Are the small screws for a 2.5 HDD? I will contact you with the temporary account and password in a message after purchase. I don't smoke, and I don't have any pets. It will be shipped in a cardboard box that just fits the product box.
