Maintenance Settings - Disk Scan
Disk Scan: The Disk Scan Target is the disk that is to be scanned. The Internal HDD option is for LinkStation’s internal hard drive. If a USB Hard Drive is connected to LinkStation, then it will also be available from the pull-down menu. Please select the disk that should be scanned. If both disks are to be scanned, then the Disk Scan must be run twice; once for each disk.
Disk Scan Type: The Disk Scan Type pull-down menu allows you to select whether the Disk Scan is to be a Normal or a Thorough scan. A Normal scan is a fast disk scan. The Thorough Scan will scan every sector individually. The Thorough Scan can take up to several hours to complete. It is recommended that you not access LinkStation or turn LinkStation off during a Thorough Scan.
