Abstract: In one embodiment, a data storage device comprises a buffer, a buffer manager, and a buffer client. The buffer client is configured to receive data to be stored in the buffer, to compute a difference between a bank boundary address of the buffer and a starting buffer address for the data, to generate a first data burst having a length equal to the computed difference and including a first portion of the data, and to send the first data burst to the buffer manager, wherein the buffer manager is configured to write the first data burst to the buffer.

Abstract: A data storage device is disclosed comprising a non-volatile memory (NVM) including a plurality of sectors each having a sector size. An access command is received from a host, wherein the access command identifies a plurality of host blocks having a host block size less than the sector size. A plurality of the host blocks are mapped to a target sector. When the target sector spans an encryption zone boundary defined by the host blocks, a NVM command is generated identifying a first key corresponding to a first encryption zone and a second key corresponding to a second encryption zone. The NVM command is executed as a unitary operation to access a first part of the target sector using the first key and access a second part of the target sector using the second key.

Abstract: A flange wrench for tightening and loosening pipe flanges onto/off of pipes has a drive head and an elongate handle. The drive head has a flat planar surface essentially parallel to a longitudinal axis of the wrench handle, and a pin extending therefrom essentially normal to the plane of the essentially planar surface. The head also includes a first essentially planar shoulder surface that is adjacent to and generally normal to the first planar mating surface, such that the planar shoulder surface is generally parallel to the axis of the pin. To use the flange wrench, the user inserts the pin into an existing or drilled mounting hole in the flange and positions the wrench planar mating surface against the planar surface of the flange such that the flange wrench planar shoulder surface is adjacent the circumferential edge of the flange.
