E.G. Then, to know where it ended, you added the size from TD's log (204800 + 2048) = 206848 -1 = 206847
Yes/No. (No )
NTFS keeps a copy of the first sector of the bootsector (the one with the actually relevant data, the BPB) as last sector of the partition, (this sector is outside the filesystem but inside the partition or - if you prefer, a NTFS filesystem is always one sector less than the size of the partition it occupies).
I wanted a copy of sector LBA 206847 in the case sector LBA2048 had issues.
Additional Question if I may ask you:
1. Why for sector "6498304" did you ask for 8 Sectors and not 16?
I'm guessing you were trying to see if there was a valid VPR, but why only 8 sectors?
Naaah (see below).
2. What software did you use to both: see the VPR that popov extracted from his HDD? and to create the MBR you sent him?
I tend to use Tiny-hexer (with my little viewers for it):
and my CHS-LBA spreadsheet:
3. In theory, if the first absolute sector of my HDD where resides the MBR, somehow was physically damaged, is there a way to keep functional the HDD, e.g. relocating the MBR to sector #2 or whichever is not damaged?
You might probably be able to create a HPA , but it may depend on the specific device (make/Model).
Most hard disks - automatically or through really low-level tools that may (or may not exist/be available/be compatible with your disk) - should be able to relocate a bad-sector.
You normally should not need to do that, and if you actually *need* to do it your best option is usually to get anyway a working hard disk as a replacement.
Here's the TestDisk log from above:
LBA 0 - 1 sector - MBR
LBA 2048 - 16 sectors - NTFS VBR
LBA 206847 - 1 sector NTFS VBR
LBA 206848 - 16 sectors NTFS VBR
LBA 6498304 - 8 sectors <-see below
LBA 234436607 - 1 sector // Corrected NTFS VBR
Try making 786432*8 .
The 8 sectors are "arbitrary" it's just the very beginning of the $MFT (and indirectly a way to make sure that the data in the VBR's @206848 and @234436607 is valid).
I normally use the first 8 sectors of the $MFT as they correspond to 4 records, i.e. exactly to what is (should be) in the $MFT Mirror.
If you prefer, if the contents of those 8 sectors seem "queer", one can later check the $MFT Mirror and hopefully correct the $MFT, but anything beyond the first 4 records (or 8 sectors) is not mirrored anywhere and so it is pretty much pointless at this stage to have anything more than 8 sectors, as they cannot be rebuilt from the $MFT Mirror.
