And the MBR you posted is a PBR or VBR or volume boot sector, NOT a Master Boot Record. :whistle:.

This was what would be the MBR according to Hex Workshop.  Remember this is via the USB external adapter so if this alters what you wanted to see you better explain in detail the program and method you use to acquire the MBR.

I already stated prior that anyone who wanted the opportunity to make suggestions of tools you wanted used for any information gathering rather than complain about not seeing the MBR which you didn't care about.

But given you identify this as a PBR/VBR what interesting tid bits did you decipher and salivate upon MR. MBR/PBR/VBR analyst? :P

No kidding.  It was meant to preserve the data so someone like you or anyone into analyzing this could copy and analyze the information rather than a static photo snapshot.

Naah.

First physical sector of the disk (or \\.\PhtsicalDrive) is the MBR.

What you posted is NOT the MBR, it is the PBR (and starts on sector 63 of the disk, i.e. on first sector of the volume).

You somehow chose the Volume instead of the \\.\PhysicalDrive in Hex Workshop.

I posted an image of the data with its common interpretation, and from it you can easily see which tools I used.

By convention these data is visualized in 16 byte wide format, not 14.
