When you convert an internal hard drive into an external drive, you can connect it to your PC using a standard USB connection.
How to Convert Internal Hard Drive to External Hard Drive
To use an internal hard drive externally, follow these steps.
Choose an internal hard drive. You can mix and match almost any hard drive and enclosure, but check the manufacturers’ websites to make sure the drive and enclosure are compatible, just in case.
Mount the drive into the enclosure. Inside the enclosure, there may be a place to mount the internal hard drive into the enclosure, either with screws or hardware (some fit into the connector). If you are installing older drives, such as EIDE or IDE, you may see multiple wires connecting the hard drive. For SATA or mSATA drives, you should see a single SATA connector, like the one in your PC.
