It supports IDE and SCSI hard disks, and can work with FAT, NTFS, and ext2/ext3 file systems. MHDD can detect and repair physical and logical disk errors, check file systems for errors, perform low-level disk formatting and surface analysis, and perform disk imaging and cloning. It also has advanced features such as sector editor, disk editor, and SMART monitor. MHDD is a powerful tool for helping to diagnose, repair, and recover data from failing hard disks.
Discontinued The program is no longer updated since 2011, but it is compatible with Windows 10 and can still be purchased on the official website.
