PowerShell: Стирание диска

PowerShell: Стирание диска

  • •

Небольшой скрипт, который обнуляет #HDD / #SSD и создаёт файловую систему заново.

Параметры

  • -DN -P_DiskNumber - номер диска. Можно узнать командой Get-Disk. Но если не ввести номер диска в параметры скрипта при запуске, скрипт сам выведет информацию и спросит номер диска. Обязательный параметр.
  • -DL -P_DriveLetter - буква будущего тома. При создании тома, ОС должна присвоить ему букву. Обязательный параметр.
  • -FS -P_FileSystem - файловая система. Может принимать следующие значения:
    • 'FAT' - файловая система FAT.
    • 'FAT32' - файловая система FAT32.
    • 'exFAT' - файловая система exFAT.
    • 'NTFS' - файловая система NTFS.
    • 'ReFS' - новая файловая система ReFS.
  • -FSL -P_FileSystemLabel - метка файловой системы.
  • -S -P_Sleep - перерыв между командами (в секундах).

Примеры

Скрипт, запущенный без параметров, сам спросит необходимые данные:

Терминал
1

.\pwsh.disk.erase.ps1

Обнулить диск 3, новому разделу присвоить букву E, форматировать в NTFS и указать метку USB-SSD:

Терминал
1

.\pwsh.disk.erase.ps1 -DN 3 -DL 'E' -FS 'NTFS' -FSL 'USB-SSD'
