This disclosure describes the use of a thermally sensitive (thermochromic) tape on a hard disk drive for easy visual identification of disks in a data center that are designated for a repair action. The tape is provided on a user facing side of each HDD in a tray on each rack of the data center. The thermochromic tape is selected such that its color is different for different surface temperatures of the HDD within the expected operating temperature range of the HDD. When a disk designated for repair is spun down (de-energized) in preparation for repair action, its surface temperature is lower in comparison with that of adjacent HDDs. The color of the tape enables easy in-place visual identification of such a disk.
