    If the hard drive came from a laptop it will be Form factor 2.5".

    If it came from a tower it will be a 3.5" This will come with a power adapter to supply 12V

    Depending on how old the drive is it will be IDE PATA interface or more likely the newer SATA interface

    If you are still unsure of the connection take a photo of the connectors and update to here

    There's three things to check:

    1. The size of the hard drive, whether it's 2.5" (laptop-sized) or 3.5" (desktop-sized). The size of the case should match, though a 2.5" drive will fit in a 3.5" case

    2. The type of connector. Unless it's an old hard drive, it's going to be SATA as that's been the standard for years.

    3. What do you want to connect it to, it could be USB 2, USB 3.0, USB-C, maybe Thunderbolt or FireWire if it's a Mac.

    Look at the connector on your hard drive. SATA or IDE. That will determine what case to get.
