Playing Janet Jackson's 1989 hit "Rhythm Nation" near certain laptops manufactured from 2005 onward can cause malfunctions, particularly affecting their hard drives. This issue was highlighted by Microsoft employee Raymond Chen, who noted that a major computer manufacturer had to create a custom audio filter to address specific sound frequencies that could disrupt 5,400 RPM hard drives. The problem was serious enough to be listed in the NIST National Vulnerability Database. The audio filter remained in use until at least the Windows 7 era, and there was a hardware vendor that sought an exception to a rule requiring users to disable all audio processing, citing potential physical damage to computers if the audio processing was disabled. Chen expressed uncertainty about whether this rule still exists today.

A bug affecting Windows XP caused crashes when playing Janet Jackson's "Rhythm Nation" on certain systems, linked to a natural resonant frequency that interfered with 5400rpm hard drives. Microsoft and an OEM developed a custom audio filter to eliminate the problematic frequency, which remained in place until Windows 7 introduced new rules allowing users to disable audio filters. This posed a risk of hardware damage for those unaware of the bug. The OEM received an exemption from the new rule to keep the audio filter active, protecting both their reputation and Microsoft's. The identity of the OEM remains undisclosed, referred to as "Fabrikam" in documentation.
