That is the problem, the site
(and software) is written by Russians and only the software is in English. My 'Russian' will be just as bad as yours, but I found out about this software from a blog.
I added two attachments, which are log files of my download software. In there should be the direct link to the files. Hopefully those files are still available. When that is not the case I can mail whichever one you prefer, as I don't think that a site like DC is allowed to host them. The first attachment is for the .ISO the second for an .EXE to be stored on a bootable DOS floppy.
MHDD is able to do a lot of things, check your hard-disk is just one of them. It is also possible to adjust the size, create bad sectors (?), hide/enable data, .BAT scripting and a lot of things more. But be warned, make an error and you are in serious trouble. By default the software is setup to check harddisks, only when you have manually changed something the software will do as you have ordered.
Personally, I have used the software only to check several harddisks here and no complaints about that functionality. When I have a harddisk with a serious problem, I like to play with the other features of this software though
