BlockDevice

Install via npm

$ npm install blockdevice

Usage

var BlockDevice = require( 'blockdevice' )

var device = new BlockDevice({
  // A custom 'fs' instance, defaults to require( 'fs' ) (optional)
  fs: null,
  // A file descriptor, if you have (optional)
  fd: null,
  // Path to the device
  path: null,
  // Mode defaults to 'rs+' to bypass local cache (optional)
  mode: 'rs+',
  // Device block size in bytes (optional)
  blockSize: -1,
  // Device size in bytes (optional)
  size: -1,
  // Heads per Track (for CHS addressing)
  headsPerTrack: -1,
  // Sectors per Track (for CHS addressing)
  sectorsPerTrack: -1,
})
