MHDD 4.6 Free Download For Windows Latest Version



Excellent program for diagnosing hard drives

MHDD apk download is a service utility for Windows designed to test the file structures on “hard disks”, in order to restore damaged information stored there due to mechanical impact or software errors during operations.

Synchronizing drives via ATA/SATA, IDE, USB, and SCSI interfaces. Support for USB-> SCSI emulation interface. Allowing “viewing” SMART attributes of information storage; equipped with low-level formatting tools that repair broken filesystem sectors on information drives; “reparating” “broken sectors in file systems via “repairing”.

MHDD functionality

  • Launches both “executive part” and “management interface” by means of an MC-DOS emulated environment (including from boot disk or its image).
  • Synchronization occurs through either an ATA/SATA, IDE, USB or SCSI interface.
  • Scan information storage file system sectors to identify “problem areas”.
  • Analyses the performance of “hard components” (“hardware”) of an information storage device, displays an overview report in an interface application and alerts users of potential hardware problems.
  • Retrieves technical data about data stored on failed sectors and recreates its original structure on “working” sections of drives.
  • Load data about the current SMART attributes of selected media.
  • Simulates USB to SCSI connectivity using an internal draveira emulator.
  • Recognizing “broken” sectors of a drive’s file system and disabling them to shift data writing operations towards those which still work, so as to reassign writing orders to “working” sectors is now more reliable.
  • Creates low-level formatting of an assigned data collector.

Utility features

  • Accuracy of pinpointing “problem” spots.
  • Ability to synchronize via ATA/SATA, IDE, USB, and SCSI; plus USB interface emulation into SCSI mode.
  • Recovery functions exist for damaged data files.
  • View Current SMART Attributes with Tools Available.
  • MHDD windows 7 low-level formatting options.
  • Independent analysis of both soft- and hard-components of an information carrier.


  • Smart attributes cannot be edited.
  • Recovery of information stored on “broken” sectors may not always be successful.
  • Emulating USB to SCSI conversion may cause errors to surface within its filesystem; these issues are “cured” by formatting.
