• Reading a Master Boot Record
• Partitioning
• Detecting block & device size

• Add hint / list of examples and what they do
• Add proper API documentation, not just that bloody list

Since reading & writing to a physical device is proving to be more and more difficult in JS land (see npm/npm#7029 and #1), implement reading & writing as a native addon.

Also, other features that could be added this way:

• Retrieving a device list in a reliable way
• Properly detecting block & device size
• Retrieving other device parameters

I'm using the library to correctly override the MBR of an sd card on OS X, however I'm having trouble doing the same on Windows 8, as even when write returns the correct bytes written, the changes are not reflected on the disk.

var device = new BlockDevice({
  path: '\\\\.\\PhysicalDrive1',
  mode: 'w+',
  size: 512
});

device.write(0, myNewMBRBuffer, callback);

Did you try this yourself? I appreciate if you can give me any clues if you encountered the same issue.
