Invalid FAT boot sector

How to use TestDisk to recover lost partition

Invalid FAT boot sector

Postby manishchy84 » 07 Sep 2012, 19:15

Hi, I am having exactly same issue like on damaged-1to-hd-t61.html.

I accidently deleted partition- 500 GB Hard drive with two partition/Intel.

1st Analyse cylinder search - Out of two partition , one was recovered.
2nd Analyse cylinder search - Getting an "Invalid FAT boot sector" and This following partition can't be recovered error.

HPFS - NTFS 0 1 1 12753 254 63 204892947
check_FAT: can't read FAT boot sector
Invalid FAT boot sector
0 D FAT32 140297 224 27 305976 78 7 2661623918
FAT32 140297 224 27 305976 78 7 2661623918


The harddisk (500 GB / 465 GiB) seems too small! (< 2516 GB / 234
Check the harddisk size: HD jumpers settings, BIOS detection...

The following partition can't be recovered:
Partition Start End Size in sectors
> FAT32 140297 224 27 305976 78 7 2661623918


> I Followed "http://forum.cgsecurity.org/phpBB3/damaged-1to-hd-t61.html" and run Advance to Rebuild BS
I get this error- "A valid NTFS Boot sector must be present in order to access any data; even if the partition is not bootable."

Here is the screen shoot:-
