我正在尝试修复格雷德迷你1TB外置硬盘上的GPT损坏分区表.以下是gdisk的报告：

root@philippe-desktop:/home/philippe/thomasdisk# gdisk /dev/sdb

GPT fdisk (gdisk) version 0.8.8

Caution: invalid main GPT header, but valid backup; regenerating main header

from backup!

Partition table scan:

MBR: protective

BSD: not present

APM: not present

GPT: damaged

****************************************************************************

Caution: Found protective or hybrid MBR and corrupt GPT. Using GPT, but disk

verification and recovery are STRONGLY recommended.

****************************************************************************

Command (? for help): ?

b back up GPT data to a file

c change a partition's name

d delete a partition

i show detailed information on a partition

l list known partition types

n add a new partition

o create a new empty GUID partition table (GPT)

p print the partition table

q quit without saving changes

r recovery and transformation options (experts only)

s sort partitions

t change a partition's type code

v verify disk

w write table to disk and exit

x extra functionality (experts only)

? print this menu

Command (? for help): v

我的理解是,gdisk可以自动解决损坏,只需按w就可以修复我的磁盘,但我不确定通常v(验证)选项应该向我提出revovery选项.

我可以安全地去按w吗？我已经做过sgdisk -b backup.gpt / dev / sdb
