Win 10 x64. My BIOS detects it like nothing is wrong. It isn't seen in disk management either which seems to be the go-to solution on the internet. I went into the BIOS and it said Hard Disk Drive so I changed it to Solid State Drive and that didn't do anything either. It's an old ass SSD that my friend just had laying idle in his PC case for years since he didn't know what it was, but it worked just fine in my other Windows 7 PC, so I formatted it without any problems so it should be perfectly fine I think. This is just really weird lol im probably just stupid
