WD Green 2TB high Power On Hours and Load Cycle Count – Seed server veteran

A WD Green 2TB hard drive that has been running for many years can show unusually high Power On Hours and Load Cycle Count values. A recent WD Community discussion involves a WD Caviar Green 2TB drive that was originally used in a desktop computer and later operated continuously in a seed server.

According to the discussion, the drive had accumulated approximately 98,693 Power On Hours and more than 1.42 million Load Cycle Counts. Interestingly, its sector-related SMART indicators, including reallocated and pending sectors, were still reporting healthy values.

Power On Hours indicate how long a drive has been powered and operating. Load Cycle Count measures how many times the drive's heads have been parked and unloaded. A very high Load Cycle Count can be a concern for an aging mechanical hard drive, particularly when the drive has spent years operating continuously.

One important point is that healthy sector information does not guarantee that an older hard drive will continue operating indefinitely. SMART monitoring can identify many potential problems, but it cannot predict every mechanical or electronic failure.

For a drive with extremely high operating hours and load cycles, users should prioritize their data. Make a complete and verified backup before attempting further troubleshooting or continued use. If the information stored on the drive is important, replacing the aging drive is a safer approach than waiting for bad sectors or another obvious failure to appear.

The WD Community discussion also notes that an old drive may continue functioning, but age and extensive usage should be considered when deciding whether to retire it.

Ultimately, SMART values are useful for monitoring drive health, but they should not be treated as a guarantee. Regular backups and timely replacement of heavily used mechanical drives can help reduce the risk of unexpected data loss.
