Systems and methods are disclosed for resource allocation for multi-actuator systems. In some examples, a data storage device can include two or more independently moveable voice coil motor (VCM) actuators where the resources of the system to operate the VCM actuators are divided. The disclosure here describes methods to allocate or re-allocate the divided resources, such as unused resources, to a VCM actuator that has a need for more resources. The methods and systems herein can also be applied to other actuator systems.

Systems or methods can be used to detect evidence of tampering. The tampering can be physical tampering, such as the turning of a screw, or removal or modification of an electronic component. In some examples, a tamper detection value can be determined from a tamper detection device and compared to a predetermined tamper detection value to determine if tampering is indicated. The system can, upon detection of the tampering, halt an operation, disable device or circuit functionality, disable future operations, physically disable a device, or any combination thereof.
