MHDD v.4.6

MHDD is a service utility for Windows, for testing the integrity of the file structure of "hard disks" and restoring information stored by them, damaged as a result of mechanical impact or accumulation of software errors during operation.

Synchronizes with hard drives through ATA/SATA, IDE, USB and SCSI interfaces. Supports USB->SCSI emulation. Allows viewing SMART attributes of data drives. Equipped with integrated tools for low-level formatting. Can "repair" "broken" file system sectors of data storage devices.

MHDD functionality

• Initiates start of the "runtime" and "management interface" using MC-DOS emulation (including bootable disk or its image);
• Synchronizes with the specified data drive via an ATA/SATA, IDE, USB, or SCSI interface;
• Scans integrity of information storage file system sectors and informs about "problem places";
• Analyzes the hard (hardware) components of the data storage, displays a report in the interface and indicates the actual hardware problems;
• Retrieves from damaged sectors technical information about the stored data and recreates their initial structure in the "working" partition of the drive;
• Submits data about the current SMART attributes of the selected storage medium;
• Simulates the USB -> SCSI interface, using the integrated emulation draweir;
• Identifies "bad" sectors in drive file system, disables them and reassigns the order of data recording to "working" sectors;
• Performs a low-level format of the specified data storage device.

Utility features

• Relatively high accuracy in determining "problem" locations;
• Possibility of synchronization via ATA/SATA, IDE, USB and SCSI, as well as USB -> SCSI emulation;
• Damaged data recovery feature;
• Tools for viewing current SMART attributes;
• Ability to perform a low-level formatting;
• Powerful tools for identifying and "curing" bad sectors;
• Independent analysis of "soft" and "hard" data media components.

Disadvantages

• SMART-attributes cannot be edited;
• Successful recovery of information stored on "bad" sectors is not always possible;
• During USB -> SCSI interface emulation errors in data storage file system may occur (it can be "fixed" by formatting it).
