According to an in-house investigation and user reports', some software and operating systems are incompatible with the Intellipark feature causing endless head parking movement as the HDD continuously goes in/out of idle mode. This abnormal behavior creates stress on the HDD and that could lead to the following issues:
Loud clunking/clicking/buzzing noises every few seconds. Artificially increases the number of load-unload cycles in S.M.A.R.T. Possibly shortens life-time of the HDD. Possibly reduces performance of the HDD.
Western Digital posted a knowledge base article, where it claims that "The number of systems using such applications and utilities is limited", a statement which we believe is false and inaccurate. Sending an HDD to idle mode only after 8 seconds of activity is abnormal behavior, which much software doesn't like as they are constantly writing and reading data to/from the HDD.
