FreeBSD gpart vs IM-Magic Partition Resizer

FreeBSD gpart is the operating system’s utility for managing disk partitioning through the GEOM class. It can create, add, delete, modify, resize, inspect, and attribute partitions, using schemes including APM, BSD, BSD64, LDM, GPT, and MBR. Adding a partition can request alignment for its start offset and size. Bootcode can be written into partitioning metadata or a specified partition. Dump and restore support saving a partition table and cloning it to multiple providers. Changes may remain pending until commit or be reversed with undo. Recover addresses corrupt scheme metadata, but choosing the wrong provider can damage another GEOM class’s metadata. Show reports partition details and supports libxo machine-readable output. Gpart is included in FreeBSD, which is free and offers self-hosted installation media for multiple architectures.

IM-Magic Partition Resizer manages disks and partitions on Windows PCs and servers. It can resize, move, merge, convert, repair, clone, and back up partitions or disks, and includes a wizard for moving an operating system disk to another disk. Its rollback protection is intended to restore the prior state if a resizing operation is interrupted by an outage, crash, or another failure. The software supports FAT12, FAT16, FAT32, and NTFS file systems, as well as MBR and GPT disks. The free edition is for home users and supports Windows 11, 10, 8.1, 8, 7, Vista, and XP; paid editions add Windows Server support. Resizer Free is free and allows up to 16TB disk capacity per PC. Paid plans include options for PCs, servers, company-wide use, and technician services. Resizer Pro is $59, paid once, billed as a one-time payment with no subscription. Extending a partition requires adjacent unallocated space, and BitLocker partitions must be decrypted or unlocked before certain changes. The maker warns that formatting, wiping, and disk copying can delete data.
