Disk & OS migration, 1 MiB/4K alignment & I/O health toolkit
A Linux alternative to AOMEI Partition Assistant. Disclaimer: Independent open-source project, not affiliated with or endorsed by AOMEI Tech Co., Ltd.
Disk Migration Assistant provides disk image cloning, OS-style MBR/GPT disk migration onto larger targets, real /sys/block & /proc/diskstats alignment and health inspection, secure image wiping, and SHA-256 verification.
What it really does:
- Whole-disk and single-partition migration on disk image files (.img/.raw) with strict 1 MiB (2048-sector) / 4K alignment, automatic GPT backup header & entry-array relocation to the end of larger disks with CRC32 recalculation, optional proportional or last-partition expansion, dry-run diff preview, confirmation dialogs, and post-copy SHA-256 verification.
- 4K Partition Alignment Checker & Block Device I/O Health Inspector reading real /sys/block//queue/ geometry and live /proc/diskstats I/O counters.
- Secure Disk Image Wipe (1-pass zero, 1-pass os.urandom, 2-pass random+zero, 3-pass zero/random/zero) with readback verification and full sector-range SHA-256 & MD5 comparison.
Limitations: Inside strict Snap Store confinement, raw /dev/sd* block device read/write is blocked without manual Store block-devices approval (disk .img/.raw files work completely; install with --devmode outside the Store if raw hardware device access is needed). Resizing a partition entry during migration does not resize the filesystem inside (use resize2fs/etc. if grown).
