NodeJS: Cannot burn to Windows 8 block device

Question

I look forward to writing directly on a raw block device.

I can successfully do this with dd for windows :

> dd.exe if=myData.dat of=\\.\PhysicalDrive1 

However, I cannot do this with NodeJS. I use node-blockdevice as follows:

 var device = new BlockDevice({ path: '\\\\.\\PhysicalDrive1', mode: 'w+', size: 512 }); device.write(0, myBuffer, callback); 

device.write correctly returns the number of bytes written, but it doesn’t actually write anything to the device.

Please note that the exact code works successfully on Mac OS X (of course, substituting \\\\.\\PhysicalDrive1 with /dev/diskN ): it records my data and I can view it without any problems in Windows 8 .

What am I doing wrong?

I also tried:

• Do not avoid backslashes ( \\.\PhysicalDrive1 ), but this results in an EINV error.
• Using a logical name: \\\\.\\E:
• Detach a volume using mountvol X: /D before attempting to read / write.

I can correctly confirm the identifier of the device with which I want to write with:

 wmic diskdrive list brief 

I also tried setting mode to rs+ . The read operation seemed to work, but the stored data contained the following data related to the failure:

  X MSDOS5.0   ?    : )? xNO NAME FAT32 3ɎѼ {  ٽ|  V@  N  V@  A  U r  U u   t F -  V@  s     f  @f  ?

EDIT: The github problem thread describing more things I tried: https://github.com/jhermsmeier/node-blockdevice/issues/1 .

EDIT: All of the approaches mentioned have been tested with administrator privileges.

EDIT: I am using device.close(callback) , but omitted in the example for simplicity.
