Looks like da boyz at DELL have begun including a Ghost image with their latest computers (at least, with their laptops). See HERE. They used to provide a Restore CD, but you can only include so much data on a CD. DELL is including the Ghost image at the very END of the hard drive, where hard drive performance is slowest (good idea). There they create a separate partition, which takes up ~3.5GBs. With hard drive capacities growing so large, even with laptop computers, allocating 3.5-GB of disk space to a Ghost image is no problem. When viewed in Partition Magic, this partition shows up as: "CP/M, Concurrent DOS, CTOS" (Primary). See HERE. But this new partition creates a problem for those of us who like to create our own back-up images. ••• continued ••• You see, hard drives are limited to 4 Primary partitions. Usually this is no problemo. Your regular NTFS partition, where Windows is installed (your C drive) counts as 1. DELL also includes a tiny 50-MB (not GB) Primary partition at the very BEGINNING of the drive, a long-standing practice with them. Here they load diagnostic and troubleshooting utilities that can help in the case you do something dumb with your computer. So, including the Ghost partition, that makes 3 Primary partitions, shipped with your new laptop. Now, if you want to create your own back-up Ghost images, you may, like me, repartition you new hard drive, in order to shrink the original partition, and add a logical DOS drive or two (in an extended partition). But an extended partition, altho it may contain many logical DOS drives, still counts as 1 Primary. So, if you did this, like me, that would make 4 Primary partitions, which max'es us out. Even this would normally be no problem, except that Ghost needs a free Primary (partition) slot available to do its job. If you try to create a back-up image without a free primary slot (located in the Master Boot Record), you'll get the following error message: >>>> Unable to find a free MBR slot in the Virtual Partition DLL. To get around this, I simply deleted the CP/M, Concurrent DOS, CTOS partition (using PM8) where DELL had stored its 3.5-GB back-up Ghost image and stretched the last logical DOS drive to reclaim this extra 3.5-GB of newly "unused space", where I created my own back-up Ghost image (two of them, actually). Kudos to da boyz at DELL for taking a page from the RAD manual. For those folks who don't create their own, a back-up Ghost image can be a lifesaver. For a more in-depth look at the Dell Utility Partition, see Dan Goodell's article titled: Inside the Dell Utility Partition. It's excellent. ••• continued ••• Update 19.january.2005 Here is a note I received on this subject, which some of you might find helpful: You, sir, are a life saver! I just got a new Dell 8400, and as usual, installed PM8 to create a second partition to store some old DOS programs. That's when I found that 3.5GB partition at the end of the drive called "CM/P Concurrent DOS" and didn't have a clue what to do with it. I used Google and searched for Dell Concurrent DOS" and a link to your blog "DELL now includes back-up Ghost image in Concurrent DOS partition" appeared (Sunday: 26.September.2004, http://radified.com/blog/archives/000141.html).

This error only occurs with/from the Windows interface. You will not get it with a Ghost boot floppy.
