I got this message: -

Logical Disk Manager (LDM) is not registered.
LDM supports Windows 2000 or later.

when I cloned my D drive with Acronis, the only way I was able to get into
the Disk Manager was to remove my C drive and install a backup of it I made
earlier and it worked ok. I just cloned my E drive and the Disk Manager now
gives the same message again. I've Googled the message and found a lot of
ideas of how to fix it, but none of them work.
Can anyone help.

The first hit in a web search, is an article on Logical Disk Manager.

http://en.wikipedia.org/wiki/Logical_Disk_Manager

In Disk Management (Start : Run : diskmgmt.msc),
you'll see either "basic" or "dynamic" listed for each
disk. Dynamic disks are a slightly more complicated
option. You'd want to break out your Acronis manual,
and see if there are any special precautions for
Dynamic disks or the partitions on them. (If you have
a PDF manual, it won't take long to search for "Dynamic".)

Any time Windows has tried to "pull a fast one", and create
a dynamic disk, I've immediately changed it back to basic.
The main advantage of basic, is fewer surprises, when using
disk utilities at a later date.

So I can't answer your question, but I'd want to look
over your setup and try something a bit simpler. In your
previous thread, you mentioned having a problem booting
a clone as well. So whatever is going on, may have been there
for a while.

I tried "Start : Run : diskmgmt.msc" and I still get the same message.
I can't see if the drive was changed to Dynamic as I can't get into Disk
Manager.

On my machine, LDM is a Service, and I can see it listed in the
Control Panel : Administrator Tools : Services thing.

Logical Disk Manager

Detects and monitors new hard disk drives and sends disk volume information
to Logical Disk Manager Administrative Service for configuration. If this
service is stopped, dynamic disk status and configuration information may
become out of date. If this service is disabled, any services that explicitly
depend on it will fail to start.

Startup Type : Automatic

Dependencies : Plug and Play, Remote Procedure Call (RPC)

Path to executable : C:\WINDOWS\System32\svchost.exe -k netsvcs

What that last thing means, is explained here.

Some people tried to fix something similar here, but weren't succesful.

http://www.theeldergeek.com/forum/index.php?act=findpost&pid=240217

The funny thing is, a person with the same user name is posting
here, and used dmreg.inf to fix it. I keep a copy of my WinXP
installer CD, on a separate partition, and there was a copy of that
file in there, in the i386 folder. You can read the file with a text
editor, to see what it is doing. Right click and selecting "install"
would run it.

Another example here.

Make sure you have a backup of your C:, in case you reduce the machine
to jelly :-)

Thank you, success at last. I checked all the urls you gave and when I
checked my XP CD for dmreg.inf and couldn't find it but found DMREG a text
file, when I right clicked on it and selected Install it worked and I can now
get into Disk Manager.
Thank you, thank you,

I think I know what the difference is, between our two setups.

In the dialog below, I have "Hide Extensions For Known File Types" unticked.
That makes the ".inf" part show up. It's under Tools:Folder Options:View

I hate OSes that hide stuff.

I've now done that, the reason I previously turned it off is that I renamed
a picture file without adding the file type and got myself into more trouble.
my problem seems to be I only know enough to to get my self into trouble.

Thanks again
