To boot famous disk diagnostic tool MHDD from USB thumb drive you’ll need:
1. Not supprisingly thumb drive you are willing to use as bootable (and are ready to format it).
(We are making our bootable USB because we don’t have real floppy drive, don’t we? If you have physical floppy drive and spare diskette than you can skip this section and go straight to the b )
Unpack it in some folder and then run vhdwin.exe from it, go to driver tab and Start virtual floppy drive service.
Next go to ‘Drive 0’ tab and hit ‘Open/Create’. Set media type to 3.5″ 1.44MB and again hit create.
Now you have a virtual floppy in your virtual floppy drive to put bootable image of MHDD there. Btw mine floppy drive got “A:” disk letter, remember the one you got you will need it.
b. So let’s put on our floppy a bootable image of MHDD somehow. To do this obtain “Last version of MHDD, self-extracting floppy image.“. I got it following the google link returned for the query of “MHDD”. Run downloaded file (mine was named “mhdd32ver4.6floppy.exe”). The summoned application has no options and looks like this:
So just hit ‘Create Floppy’ confirming overwriting of content of the floppy residing currently in a drive. Wow. Now we have a bootable image of MHDD but it’s on our floppy, not on USB.
c. Now we are to move it to the USB Thumb drive. To make this happen we need another app from HP called ‘HP USB Disk Storage Format Tool‘. It can be downloaded from Softpedia. After downloading run it and it will present itself with single dialog. Select your USB Thumb drive as a device, FAT as file system, check ‘Quick Format’ and ‘Create a DOS startup disk…’ selecting floppy drive as a destination.
That will make our thumb drive bootable. But we still do not have MHDD on it. So the next step is just to copy entire contents of floppy drive to our new bootable USB drive (overwriting or not overwriting files). That’s all. Now we can boot from our USB drive.
d. So it’s time to reboot and to command your bios to boot from USB media.
Sadly but you have to make a few more moves to actually run MHDD.
After boot you will be faced with Windows 98 (!) logo and then the following selection:
I select “With ” (cause with is better than without, isn’t it =)
Than there’s beep and report of some failures. Don’t mention and just press ‘f’ until you are faced with >D:MHDD and a message that mhdd was successfully unpacked to D:MHDD. You know what I’d say: “It’s a shameless lie”. To ensure run DIR command =)
So MHDD is not actually unpacked and we are to do it manually. So execute the following commands:
c:pkunzip -e mhdd
Now we have really unpacked MHDD to c:MHDD.
So it’s time to type MHDD and hit enter. Voila!
