我对新磁盘(2TB Buffalo)进行了部分格式化,我打算将其从 FAT 格式化为 NTFS(很可能是新磁盘的文件格式)。然而,我不小心拔掉了电缆。自新磁盘以来,那里没有重要文件。我只能看到磁盘连接 /dev/disk/ 但在系统 GUI 中看不到。
我知道这个回答。我跑
ls -la /dev/disk/by-id/usb-BUFFALO_HD-PNFU3_0000000300001199-0\:0
lrwxrwxrwx 1 root root 9 Jul 10 22:59 /dev/disk/by-id/usb-BUFFALO_HD-PNFU3_0000000300001199-0:0 -> ../../sdb
和
testdisk /debug /dev/disk/by-id/usb-BUFFALO_HD-PNFU3_0000000300001199-0\:0
和
photorec /debug /dev/sdb
并没有得到任何相关的结果。
运行 Jodka 的命令
/dev/sdb
是正确的位置,因为 Buffalo 磁盘为 2TB:
lsblk /dev/sdb
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdb 8:16 0 1.8T 0 disk
并运行wipefs
命令但发现选项不存在:
$ wipefs -fv /dev/sdb
wipefs: invalid option -- 'v'
Usage:
wipefs [options] <device>
Options:
-a, --all wipe all magic strings (BE CAREFUL!)
-b, --backup create a signature backup in $HOME
-f, --force force erasure
-h, --help show this help text
-n, --no-act do everything except the actual write() call
-o, --offset <num> offset to erase, in bytes
-p, --parsable print out in parsable instead of printable format
-q, --quiet suppress output messages
-t, --types <list> limit the set of filesystem, RAIDs or partition tables
-V, --version output version information and exit
版本是wipefs from util-linux 2.25.2
.
运行最后两个命令
$ sudo mkfs.ntfs -f /dev/sdb
/dev/sdb is entire device, not just one partition.
Refusing to make a filesystem here!
$ sudo mkfs.ntfs -f /dev/sdb1
Failed to access '/dev/sdb1': No such file or directory
The device doesn't exist; did you specify it correctly?
我仍然看不到任何内容,ls /media/masi/
因此磁盘无法使用。
运行 Jodka 的补充
我没有看到磁盘/媒体/马西/在这些命令之后:
$ sudo wipefs -fa /dev/sdb
$ ls /media/masi/
$sudo wipefs -fa /dev/sdb1
wipefs: error: /dev/sdb1: probing initialization failed: No such file or directory
为什么要在 /dev/sdb1 中运行最后一个命令?我没有这样的光盘。该命令ls /dev/sd*
仅给出/dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sdb
.
再次运行最后的命令
sudo gdisk /dev/sdb
GPT fdisk (gdisk) version 0.8.10
Partition table scan:
MBR: not present
BSD: not present
APM: not present
GPT: not present
Creating new GPT entries.
Command (? for help): x
Expert command (? for help): z
About to wipe out GPT on /dev/sdb. Proceed? (Y/N): Y
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.
Blank out MBR? (Y/N): Y
$ sudo dd if=/dev/zero of=/dev/sdb bs=4M count=10
10+0 records in
10+0 records out
41943040 bytes (42 MB) copied, 1.62512 s, 25.8 MB/s
$ sudo gdisk /dev/sdb

Partition table scan:

Command (? for help): n
Partition number (1-128, default 1):
First sector (34-3907029134, default = 2048) or {+-}size{KMGTP}:
Last sector (2048-3907029134, default = 3907029134) or {+-}size{KMGTP}:
Current type is 'Linux filesystem'
Hex code or GUID (L to show codes, Enter = 8300):
Changed type of partition to 'Linux filesystem'
Command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N): Y
OK; writing new GUID partition table (GPT) to /dev/sdb.
The operation has completed successfully.
$ ls /media/masi/
$ mkfs.ntfs -f /dev/sdb
sdb sdb1
$ sudo mkfs.ntfs -f /dev/sdb
/dev/sdb is entire device, not just one partition.
Refusing to make a filesystem here!
$ sudo mkfs.ntfs -f /dev/sdb1
Cluster size has been automatically set to 4096 bytes.
Creating NTFS volume structures.
mkntfs completed successfully. Have a nice day.
$ ls /media/masi/
我终于通过运行最后让光盘工作了
$sync
// disconnect the cable and put back
$ls /media/masi/

如何恢复NTFS部分格式化的磁盘?
答案1
我了解,您没有想要保留的文件。
可以肯定的是,您正在运行正确的硬盘lsblk
来列出所有连接的驱动器。
我会首先使用wipefs:
wipefs -a /dev/sdb1
和wipefs -a /dev/sdb
然后启动gdisk /dev/sdb
并按x
然后z
擦除 mbr 和 gpt。
也许将第一个兆字节归零:
dd if=/dev/zero of=/dev/sdb bs=4M count=10
然后根据大小启动 fdisk(对于旧的 mbr)或 gdisk(对于现代的 gpt)并创建新分区。
gdisk /dev/sdb
-> n
-> ENTER -> ENTER -> ENTER ->0700
对于类型 0x0700(Microsoft 基本数据) ->w
写入磁盘
或者
fdisk /dev/sdb
-> n
-> p
-> 1
-> 输入 -> 输入;t
->7
对于类型 0700 Microsoft 基本数据 ->w
写入磁盘
然后格式化它
mkfs.ntfs -f /dev/sdb1
答案2
您可以将驱动器清零
dd if=/dev/zero of=/dev/sdb bs=1M
确保/dev/sdb
确实是正确的设备名称!
