我的笔记本电脑 SSD 被水损坏了。笔记本电脑的其余部分似乎工作正常，但是 SSD（金士顿 SNS8152S3256GG2）似乎完全失效了，操作系统根本无法启动，所以我使用 GParted 实时磁盘，并将 SSD 与 M.2 转 USB 设备连接。gparted并且fdisk -l不显示设备/dev/sda。gdisk /dev/sda有以下输出：
GPT fdisk (gdisk) version 1.0.1
Problem reading disk in BasicMBRData::ReadMBRData()!
Warning! Read error 22; strange behavior now likely!
Warning! Read error 22; strange behavior now likely!
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: not present
***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by
typing 'q' if you don't want to convert your MBR partitions
to GPT format!
***************************************************************
输出i：No partitions
输出p：
Disk /dev/sda: 0 sectors, 0 bytes
Logical sector size: 512 bytes
Disk identifier (GUID): 2E1AE37A-8EDD-4014-A35B-F7AAD7556C29
Partition table holds up to 128 entries
First usable sector is 34, last usable sector is 18446744073709551582
Partitions will be aligned on 2048-sector boundaries
Total free space is 0 sectors (0 bytes)
Number Start (sector) End (sector) Size Code Name
输出v：
Problem: Disk is too small to hold all the data!
(Disk size is 0 sectors, needs to be 0 sectors.)
The 'e' option on the experts' menu may fix this problem.
Problem: GPT claims the disk is larger than it is! (Claimed last usable
sector is 18446744073709551582, but backup header is at
18446744073709551615 and disk size is 0 sectors.
The 'e' option on the experts' menu will probably fix this problem
Partition(s) in the protective MBR are too big for the disk! Creating a
fresh protective or hybrid MBR is recommended.
Identified 3 problems!
我非常怀疑我是否能够从磁盘（包含 Windows 分区和 Ubuntu 分区）中恢复任何内容，但有什么建议可以指导我如何做吗？我应该创建一个新的 GPT 还是接受磁盘已经消失了？是否可以读取，/dev/sda以便我可以尝试 ddrescue 或 photorec？
