### timeline
- [[2026-04-04]] Note: I've got three of these, but I can only find an Amazon order for one (order#203-6721030-9941150--the earlier order#202-5215396-9390752 was returned/refunded probably because as it had [[11 Ravensbourne Court|11 Ravensbourne Court]] as the address). I don't know which one came from this order, so I've just duplicated the price and acquired dates.

	- Status: Old Age with Minor Surface Wear
	- Power-On Hours: 85,998 (~9.8 years).
	- Condition: Showing signs of age.
	- Key Metrics:
	    - Multi_Zone_Error_Rate: 12. This indicates that the drive struggled to write data to the disk surface on 12 occasions.
	    - Load_Cycle_Count: 499,046 (Extremely high).
	- Note: Like the other WD Green, this is a very old drive. The `Multi_Zone_Error_Rate` suggests the physical platter or head is starting to show its age.
