Usage

`js
var Disk = require( 'disk' )
`

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

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

Create a disk:

`js
var disk = new Disk( device )
`

Open the device:

`js
// 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:

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

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

`js
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.

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

Close the device:

`js
disk.close( function( error ) {})
``
