Tips for Reading User's Guides On-Screen When reading a ZyXEL User's Guide On-Screen, keep the following in mind: · If you don't already have the latest version of Adobe Reader, you can download it from http://www. adobe. com. · Use the PDF's bookmarks to quickly navigate to the areas that interest you. Adobe Reader's bookmarks pane opens by default in all ZyXEL User's Guide PDFs. · If you know the page number or know vaguely which page-range you want to view, you can enter a number in the toolbar in Reader, then press [ENTER] to jump directly to that page. [. . . ] The total number of spindle start and stop cycles. 04 05 Start/Stop Count Reallocated Sectors Count Low Total number of reallocated sectors on the hard drive. When the hard drive detects a read/write/verification error, it marks the sector as "reallocated" and transfers the data to a specially reserved (spare) area. The process is also known as remapping with "reallocated" sectors known as remaps. The more sectors the hard drive has to reallocate, the slower read and write speeds become. This is the margin of a channel when it reads data. 06 07 Read Channel Margin Seek Error Rate Low This is the rate of the magnetic heads' seek errors. A failure in the mechanical positioning system, such as servo damage or a thermal widening of the disk, results in seek errors. An increasing number of seek errors indicate the condition of the disk surface and the mechanical subsystem are worsening. This is an average performance indicator for the seek operations of the magnetic heads. Mechanical subsystem problems cause this value to decrease. This is how many hours the hard drive has been in a power-on state. The raw value lists the total number of hours (or minutes, or seconds depending on the manufacturer). This is the total number of spin start retry attempts. This is the number of attempts to spin up to fully operational speed the hard drive has made when the first attempt did not succeed. An increase in this value is an indicator of hard disk mechanical subsystem problems. This is the number of times recalibration was requested when the first attempt did not succeed. A decrease in this value is an indicator of hard disk mechanical subsystem problems. This is the number of times the hard drive has gone through a full power on and power off. 08 Seek Time Performance Power-On Hours (POH) High 09 Low 10 Spin Retry Count Low 11 Recalibration Retries High 12 13 19 0 19 0 19 1 Device Power Cycle Count Soft Read Error Rate Airflow Temperature Temperature Difference from 100 G-sense error rate Low Low High This is the number of uncorrected read errors the hard drive has reported. This indicates the temperature of the airflow measured by a Western Digital hard drive. This indicates the value of 100 - the temperature in degrees Celsius. Manufacturers can set a minimum threshold that corresponds to a maximum temperature. This is the number of mistakes caused by impact loads.
