Description: Guess PC disk partition table, find lost partitions
Gpart is a tool which tries to guess the primary partition table of a PC-type
disk in case the primary partition table in sector 0 is damaged, incorrect or
deleted.
.
It is also good at finding and listing the types, locations, and sizes of
inadvertently-deleted partitions, both primary and logical. It gives you the
information you need to manually re-create them (using fdisk, cfdisk, sfdisk,
etc.).
.
The guessed table can also be written to a file or (if you firmly believe the
guessed table is entirely correct) directly to a disk device.
.
Currently supported (guessable) filesystem or partition types:
.
* BeOS filesystem type.
* FreeBSD/NetBSD/386BSD disklabel sub-partitioning scheme used on Intel
platforms.
* Linux second extended filesystem.
* MS-DOS FAT12/16/32 "filesystems".
* IBM OS/2 High Performance filesystem.
* Linux LVM physical volumes (LVM by Heinz Mauelshagen).
* Linux swap partitions (versions 0 and 1).
* The Minix operating system filesystem type.
* MS Windows NT/2000 filesystem.
* QNX 4.x filesystem.
* The Reiser filesystem (version 3.5.X, X > 11).
* Sun Solaris on Intel platforms uses a sub-partitioning scheme on PC hard
disks similar to the BSD disklabels.
* Silicon Graphics' journalling filesystem for Linux.

若只是要復原分割表，用它就夠了

[THQ]

testdisk試過了,quick search 和deep search都沒用
我直接用fdisk重設定結果還是不行
invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
寫入時訊息如下

The partition table has been altered!

Calling ioctl() to re-read partition table.
Syncing disks.

用fdisk看分割表,還是未分割的樣子
