Ok so I just bought a hard drive that isn’t detected by windows or mac. idk what the drivers file name was before I bought it all I know is that it won’t connect. On a windows machine it makes that sound that something is connecting and says it installed correctly but does not show up in disk manage…

If the drive has an extra lead coming off of the wire connector you may have to plug that into a usb to gain the extra power.
