DiskScan is an app (or website) designed for scanning a computer's hard drive for errors and potential issues. It can identify bad sectors, fragmented files, and other errors that can affect the performance of the hard drive. It can also detect viruses, malware, and other malicious items that may be hiding on the system. It can also provide details about the current status of the hard drive and make recommendations for repairs or other corrective action. DiskScan can be used on both Windows and Mac operating systems.
