Okay, I'm running 64-bit Windows 7 Pro SP1, and the system had 2 non-system 2TB hard disks attached. When I tried booting up, BIBM warned of "errors" and advised me to run "Partition Work" to examine and repair the problems, so I did just that.
It reported the message "*Errors Exist*" (arguably one of the most unhelpful error message in the known universe
) on one particular drive: A model Seagate ST2000DM001-1CH1, which was MBR formatted with approximately 8 partitions, some of which were NTFS and others were of a rare type that are essentially treated as "raw" partitions (although they're properly setup in the MBR).
The letter "E", which indicates the problem areas, was shown next to the MBR and also next to the final partition on the disk, which was a normal NTFS volume. When I selected that partition for repair, I don't recall exactly which button I pressed, but the option I chose was something like Correct or Reconfigure CHS/xxx. Then I rebooted, and during that next startup, NO error message appeared.
However, after I finished booting into Windows 7, Windows Disk Manager and EVERY other similar tool I own reported that all of a sudden there were NO partitions on the disk whatsoever!
It showed the disk as completely unformatted!
To make matters VASTLY worse, I've learned that there are exactly ZERO partition recovery tools out there which can properly locate and create an MBR entry for ANY of those rare, but fully legal and proper, partitions of the type that disk once possessed! I've searched for months and months in the last year and tried dozens of them, but I promise you that there are NONE WHATSOEVER that will work!
So my only, desperate hope is that, somehow, if I go back into BIBM's Partition Work, I can "unfix" what I did and get the MBR and ALL my partition back. Is there ANY way to do that? Any at all?
