ntfsresize
resizes NTFS filesystems without data loss
TLDR
Show current size and minimum
$ ntfsresize --info /dev/[sda1]
Resize to specific size$ ntfsresize --size [50G] /dev/[sda1]
Shrink to minimum$ ntfsresize --size [$(ntfsresize -i /dev/sda1 | grep minimum)] /dev/[sda1]
Dry run$ ntfsresize --no-action --size [50G] /dev/[sda1]
Force resize$ ntfsresize --force --size [50G] /dev/[sda1]
SYNOPSIS
ntfsresize [options] device
DESCRIPTION
ntfsresize resizes NTFS filesystems without data loss. It can shrink or expand volumes, showing the minimum possible size before shrinking.
After resizing, the partition table must be updated separately (using fdisk/parted).
PARAMETERS
-i, --info
Show volume information.-s, --size size
New size (K, M, G suffixes).-n, --no-action
Dry run.-f, --force
Force operation.-b, --bad-sectors
Handle bad sectors.-P, --no-progress
Disable progress bar.
TYPICAL WORKFLOW
$ # 1. Check filesystem
ntfsfix /dev/sda1
# 2. Get info
ntfsresize --info /dev/sda1
# 3. Resize filesystem
ntfsresize --size 50G /dev/sda1
# 4. Resize partition (separate step)
parted /dev/sda resizepart 1 50G
ntfsfix /dev/sda1
# 2. Get info
ntfsresize --info /dev/sda1
# 3. Resize filesystem
ntfsresize --size 50G /dev/sda1
# 4. Resize partition (separate step)
parted /dev/sda resizepart 1 50G
CAVEATS
Unmount before resizing. Back up important data. Partition resize is separate step. Run from Live USB recommended.
