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
