I can't recommend Macrium Reflect as it failed to restore a backup
image a few months ago. Lucky for me that I had a slightly older
Acronis True Image backup which restored the drive.
I'll stick with Acronis as it has never given me a problem. I don't
have ATI installed, I use the boot disk installed on a USB stick.
According to this, you can "Verify" them.
All that does, is run through the generated .mrimg file and
compare the MD5SUM in the manifest, against what was written
to the .mrimg. It's a way of detecting a hardware failure, such
as an OS write buffer having an error in it. If you had a storage
media that suffered from "bit rot", then it would also provide
a means of detecting the media had gone bad.
You can also convert an .mrimg to a .vhd and load the .vhd
into a virtual machine. You would make it the second disk in the
virtual machine, and examine it with your forensic tools (if it
was damaged say).
And if you happen to have a copy of vhdmount, you can even mount
a .vhd file as a virtual disk (i.e. no virtual machine software needed).
That is for the older OSes which lack native .vhd mounting. I think
Windows 8 can mount a .vhd native, as well as mount ISO9660 files as
virtual optical drives, as an example of an OS that doesn't need such
assistance. For the others, there are hacks such as vhdmount.
(Obscured by ugly popup advertising. I bookmarked this back when it
It's possible I got my copy of vhdmount from here. I wouldn't need
this too often, as I have VPC2007 and VirtualBox available in other
setups. I usually carve up downloads like this, with 7zip, to get
A number of the virtual disk formats, differ only slightly in terms
of headers and the like. So if you had half a dozen different formats,
they might be very similar. I suppose Macrium might differ, in that
the body of their VHD would be compressed, and one would assume the
conversion routine they offer, would decompress it again. I don't know
if .vhd has a native compression option. I thought it was always
In fact, I had some utility, that would convert a .dd (file full of sectors
from a disk), to a .vhd, and when I ran that once, it only took a second
to convert the file. It required prepending and appending junk on either
end of the file. Something like that.
So it's like roast turkey. With a sharp knife and patience,
anything is possible.
