Statistics properties for devices
Statistics include the date the device was last mounted, device totals such as the total number of bytes written and read, and device errors. Error rates are affected by media, head cleaning, and head wear. Information includes only the statistics that are gathered after Backup Exec first discovers the device.
The documentation included with your device should list the acceptable limits for hard and soft errors; if not, check with the hardware manufacturer.
