HDClone vs OpenSuperClone

HDClone creates physical or logical copies and file images of hard disks and other storage media for backups, system copies, and recovery of defective media. It works independently of partitioning scheme, file system, and operating system, including with some otherwise inaccessible proprietary formats. Depending on edition, it supports drive and partition copies, SmartCopy, PartitionSelect, and copying to multiple targets. File-image options vary by edition, with higher editions adding compression, password protection, differential or encrypted images, and virtual disk formats. Professional and Enterprise editions can create VMDK, VHD, VHDX, and VDI images for VMware, VirtualPC, and VirtualBox virtual machines. It runs as a Windows application or from bootable CD/DVD or USB media. The Free Edition costs nothing, for private use only, and is limited to 4 TB and 70 MB/s. Basic costs €19.90, paid once and is limited to private use on up to two PCs; higher one-time editions add further capabilities.

OpenSuperClone is a free Linux data-recovery utility based on HDDSuperClone. It provides advanced drive cloning and logs the recovery process so it can be stopped and resumed. Virtual Disk Mode supports targeted extraction and can read from the source, destination, or neither, including workflows with DMDE, R-Studio, and UFS Explorer. Direct AHCI and IDE modes can bypass operating-system drivers, while the project documents direct USB access. The utility can power-cycle drives through generic USB HID relay boards or YEPKIT YKUSH switchable hubs. A script engine supports advanced drive interaction, with a Visual Studio Code language extension available. Downloads include DEB and RPM packages, source installation instructions, and a Linux Live ISO. OpenSuperClone is GPLv2 licensed. Virtual drive functions need a kernel module. NVMe SSDs require Generic Source Device Mode because they do not appear in default passthrough mode. Wiki documentation is incomplete.
