WD Assigned Two Patents

Automatically configuring web browser file when booting OS from storage device
Western Digital Technologies, Inc., Irvine, CA, has been assigned a patent (8,914,625) by Morris James Dean, Newport Coast, CA, for a “automatically configuring a web browser file when booting an operating system from a data storage device.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage device is disclosed comprising a non-volatile memory having a host operating system stored in an unprotected area of the non-volatile memory, a device operating system stored in a protected area of the non-volatile memory, and a device application operable to modify a web browser file, the device application stored in the protected area of the non-volatile memory. When a first read command is received from a host to load the host operating system, the device operating system is returned in response to the first read command. A second read command is then received from the host to load the device application, and a write command is received from the device application executing on the host to modify the web browser file.“

The patent application was filed on July 31, 2009 (12/534,083).

HDD reducing write unsafe threshold
when detecting unrecoverable servo compensation value
Western Digital Technologies, Inc., Irvine, CA, has been assigned a patent (8,913,338) by Chahwan Alain, Irvine, CA, Huang Yanan, Torrance, CA and Ji Chuanwen, Irvine, CA, for a “disk drive reducing write unsafe threshold when detecting an unrecoverable servo compensation value.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A disk drive is disclosed comprising a disk comprising a plurality of servo tracks defined by servo sectors, wherein each servo sector comprises servo data and a servo compensation value. While servoing a head over a target data track during a write operation, a position error signal (PES) is generated at each servo sector based at least in part on the servo data. When the servo compensation value of a first servo sector is recoverable, the write operation is aborted when the PES generated at the first servo sector exceeds a first write unsafe threshold. When the servo compensation value of the first servo sector is unrecoverable, the write operation is aborted when the PES generated at the first servo sector exceeds a second write unsafe threshold less than the first write unsafe threshold.“

The patent application was filed on June 24, 2013 (13/924,791).
