$ npm install --save disk

Internals:

• MBR – Master Boot Record
• GPT – GUID Partition Table
• CHS – Cylinder-Head-Sector Addressing
• apple-partition-map – Apple Partition Map
• BlockDevice – Block device handling
• RamDisk – In-memory block device

Block Devices:

• VHD – Microsoft Virtual Hard Disk format
• UDIF – Apple's DMG / UDIF (Universal Disk Image Format)
• UDF – OSTA Universal Disk Format

File Systems:

• FAT32 – FAT32/16/12 file system driver
• ExFAT – ExFAT file system driver
• HFSX – Apple HFS+ file system driver
• NTFS – NTFS file system driver

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 ) {})
