Usage

var Disk = require( 'disk' )

Set up a device to work with. This can be anything with a blockdevice compatible API.

var device = new BlockDevice({
  path: BlockDevice.getPath( 0 )
})

Create a disk:

var disk = new Disk( device )

Open the device:

// This also attempts to detect it's block size if unspecified,
// as well as reading the MBR & GPT on the device
disk.open( function( error ) {})

Read or write the MBR (disk.mbr) from or to the device:

disk.readMBR( function( error, mbr ) {})
disk.writeMBR( function( error ) {})

Read or write the GPT (disk.gpt) from or to the device:

disk.readGPT( function( error, gpt ) {})
disk.writeGPT( function( error ) {})

Verify the backup GPT; NOTE: The callback will be called with an error and the backup GPT if it doesn't verify.

disk.verifyGPT( function( error, backupGPT ) {})

Close the device:

disk.close( function( error ) {})
