# sgdisk
|
|
|
|
> Manage GUID Partition Tables (GPT).
|
|
> Part of the GPT fdisk suite; designed for scripting and automation.
|
|
> More information: <https://manned.org/sgdisk>.
|
|
|
|
- Display basic GPT partition summary data for a device:
|
|
|
|
`sudo sgdisk {{[-p|--print]}} {{/dev/sdX}}`
|
|
|
|
- Wipe both GPT and MBR data structures from a device (destroys all partition information):
|
|
|
|
`sudo sgdisk {{[-Z|--zap-all]}} {{/dev/sdX}}`
|
|
|
|
- Convert a GPT disk to MBR format using up to four partitions:
|
|
|
|
`sudo sgdisk {{[-m|--gpttombr]}} {{1:2:3:4}} {{/dev/sdX}}`
|
|
|
|
- Delete a partition entry by number (data in sectors remains untouched):
|
|
|
|
`sudo sgdisk {{[-d|--delete]}} {{1}} {{/dev/sdX}}`
|
|
|
|
- Save the current in-memory GPT data (protective MBR, headers, and table) to a binary backup file:
|
|
|
|
`sudo sgdisk {{[-b|--backup]}} {{/path/to/backup.gpt}} {{/dev/sdX}}`
|
|
|
|
- Load GPT data from a backup file (restoring from a non-original disk is not recommended):
|
|
|
|
`sudo sgdisk {{[-l|--load-backup]}} {{/path/to/backup.gpt}} {{/dev/sdX}}`
|
|
|
|
- Verify GPT structures for CRC errors, mismatches, or inconsistencies:
|
|
|
|
`sudo sgdisk {{[-v|--verify]}} {{/dev/sdX}}`
|
|
|
|
- Display a summary of available partition type codes (no device required):
|
|
|
|
`sgdisk {{[-L|--list-types]}}`
