Abstract: Apparatus and method for distributing power to a host computer (112). A first serial cable (145) establishes a first data link (146) and a first power transfer link (148) between a first serial port of a peripheral device (110) and the host computer. A second serial cable establishes a second data link (146) and a second power transfer link (148) between a second port of the peripheral device and an external power supply unit (PSU). A peripheral controller circuit (114) detects available power from the external PSU at a level suitable for use by the host device, notifies the host computer of the available power from the external PSU, and interconnects the first and second serial ports to flow the available power to the host device via the first and second power transfer links. The peripheral device may take the form of a solid-state drive (SSD) (110) with a non-volatile memory (118), such as flash memory.

Abstract: The technology disclosed herein provides a method to control the resources used in a device. An implementation of such a method includes generating a device configuration ledger block based on initial assembly of components of a storage device, storing the device configuration ledger block on a node of a distributed ledger, detecting an activation of the device; in response to detecting the activation of the device, generating a current distributed ledger block based on current assembly of components of the storage device, comparing the current distributed ledger block with the device configuration ledger block, and in response to determining that the current distributed ledger block does not match with the device configuration ledger block disabling the operation of the device.

Abstract: A heater power of a heat-assisted magnetic recording head is set to an initial power to induce an initial head-medium clearance. For a plurality of iterations, a heater power at an optimum laser power is determined that achieve a target clearance. If differences in the heater power and optimum laser power between the two subsequent iterations are below a threshold, the iterations are stopped and the heater power and the optimum laser power for one of the two subsequent iterations is used as an operational heater power and laser power for the heat-assisted magnetic recording head.

Abstract: A magnetic recording head comprises a transducer, a heater, a writer and a laser. The transducer is configured to write to a magnetic recording medium during a write operation. The heater, writer and laser are configured to affect a protrusion of the transducer. The heater is calibrated to produce a pre -write heater power to obtain a target pre -write clearance for a write operation through use of a clearance-heater power curve. The curve is generated by measuring a clearance between the transducer and the medium as the heater is cycled from zero to a contact power.

A first identifier value (202A, 222A, 242A, 262A, 282A, 306A) is stored on an external surface of the housing and a second identifier value (202B, 222B, 242B, 262B, 282B, 306B) is stored within the memory. A digital signature (210, 256, 296) generated in response to the first and second identifier values and in response to a private key (208, 254, 288) is stored on the storage device. Thereafter, the first identifier value is retrieved from the external surface of the housing and the second identifier value is retrieved from the memory. The storage device is authenticated using the retrieved first and second identifier values, the digital signature and a public key (228, 274, 312).
