Some important information! The first version was released in by Dmitry Postrigan whose main objective was to develop well-known and trusted HDD diagnostic tool.
MHDD now includes features to access raw sectors, view S. You can issue a sequence of commands using simple scripting. The BIOS looks into its tables to find where that drive is attached, checks ranges and then starts sending commands to the drive.
This diagram shows how a DOS program talks to the drive. You can turn on your drive after DOS boots A small risk of drive damage exists if you are not careful. This will cause data loss on both devices on that channel! Some RAID boards are supported. LBA mode is supported in full.
LBA48 mode is supported. Take the executables and build your own system. MHDD package contents mhdd. The CD is removable and you can insert a different CD having an editor or other programs. First run. Some important information MHDD is very easy to use.
Knowing what to have MHDD do is not easy! It is very important to understand that you have to spend several hours minimum before you will start using MHDD. Primary IDE channel is disabled. To enable it, first read read this warning message, then edit MHDD.
Have a DOS formatted floppy ready for saving logs, screenshots and config files. Adding a tiny editor like vi. Remember floppy is B: if you booted from the CD. Example: ID and EID display detailed information about the drive. Start: hh:mm:ss Average Access Time: Maximun: Different manufactures and different models provide different information. This reports the number of remaps on the drive. This should be ZERO. If it is more than 50 — you have a problem.
Check for bad power supply especially the fan , vibration and overheating. If not change the cable! Overclocking may result in increased error rate.
Log EF found. Log F0 found. This would permit switching to another drive and starting an off-line test on multiple drives. Test will abort an "in-progres" off-line test. Start with since it's really quick. Use smart data to see the results.
It has been know to return an error the first time, issue it again. If you booted from the CD there will, most likely, be insufficient space for the log file on the RAM drive.
If the target drive is less than 10GB the log will fit on a floppy. To create the log on a hard drive : this means there must be one with a FAT partition which you are willing and able to write to.
Press [F4] again to start the scan. One block is sectors , bytes. During the scan you can have MHDD jump around. Drive registers are displayed at the top of the screen. BUSY appears when drive is executing read or write command, or executing an online test.
INDeX flag is also obsolete, but sometimes blinks. The brightness of the blocks reflects the length of time to read the sectors. Longer times are most likely do to the firmware performing a retry of a marginal spot. It is normal for a checker board like pattern to scroll across the screen. A table on the right shows the number of blocks in each time range. If an error occurs a letter describing the type is shown?
Save the scan log! A blue block indicates remapping in progress. Check smart att Of special interest are: 5 Reallocated sectors count: this should be zero! Reruning the scan most likely will show the same errors since the hardware firmware has already done multiple attempts to read the data. If you see all blocks as errors STOP. You are dealing with service-area error which cannot be fixed by MHDD. The best option contact the manufacturer for a Return Materials Authorztion, or discard the drive.
You can write several sectors or the whole drive to a file or to set of files. Note: decreasing the sound level is done by increasing the seek time!
You can also cut or uncut the drive by using this command. Some manufacturers are using Device Configuration to artifically reduce the size of a disk.
This is the fastest erase and cannot be stopped. In this state the drive will continue the erase unless it is unlocked after being partially erased if the internal password is known.
Notes at CMMR. Enter the new MaxLBA number, in sectors. PWD command locks a drive with defined user password. FAQ is available here: forum. As I am trying to make it useful, it is much better to give a link to this page instead of copying something from here. You may distribute MHDD without any limitations while you preserve copyrights. You can disassemble reverse-engineer MHDD for educational purposes. You cannot sell MHDD program or any its parts.
