You can find out what a HDD looks like by listening to the platter on it. Is there something wrong with SSDs that do not have such active components? You can only find out if it is working by installing the software. For Windows operating system, free software called Crystal Disk Mark, and for Mac OS, smart reporter lite is recommended.
