I have some work related HDD that are used to record infield activity. These hard drive should come back to us with video data on it. The last couple we have received don't show naturally when plugged into the computer and when I go to the drive management it shows up as drive 2 - 6 with drive 4 and 5 the only ones with letters attached and drive 6 the only one that shows the information about the drive.
I opened the drive in FTK and found the following "Invalid partition table. Error loading operating system. missing operating system" I have done a live acquisition with FTK5 but there are no files on the system. I have used Easeus partition master and so far nothing has helped.
Any ideas on what else I can do or has the data disappeared. The files are nothing exciting just normal run of the mill MP4
Are these from a security camera (or similar). As far as I am aware, many of these systems do not use standard file systems so the video area may be just raw data.
There can be many variations!

You are probably just looking a the MBR (Master Boot Record or first absolute sector of the device or LBA0) in a hex editor/viewer.
Those are the "standard" error messages that are embedded in *any* MBR code (of MS origin).
It is well possible that (for *any* reason) the actual data (partition table entires) are corrupt or invalid (or they may only contain an "unmountable under Windows" partition type ID).
It is important that you check (or find someone with the needed knowledge/experience with data recovery) the MBR data.
A basic run of TESTDISK

or dmde

on that disk should be enough to see if partition entries make sense or not.
