    First thing you're going to do is fill in the specs of the desktop whose snips you are showing us.

    Then you're going to do the same with the second pc opening a second post with snips. Give it a different title like "Second pc with drive letters the same". Don't forget the snips.

    You should not have dynamic disks in either machine. What did you do to accomplish this?

    There exists a bevy of spectacular experts on this site that will be happy to help you. But give us ALL the info please.

    What you have created is a "Spanned Volume" of those partitions, a feature of the Dynamic Disk System.

    Pscowboy is right: you do not want to have your Windows machine set up with Dynamic Disks. They should be Basic Disks.

    The subject is covered well here:
    What is the Dynamic disk? Data recovery, backup and manage dynamic disk easily.

    To correct this you first must work to back up your data. If you do not have a backup drive or external drive get one. While there are conversion options that can try and retain your data they can go wrong for several reasons.

    Then you can do the conversion as explained here:

    thanks sir ....i know that there should be basic disk. but the snips are real.....please tell me what kind of information you want.....the partition tool which showed in the link are not working.... partition tool says a error massage " partition wizard cannot convert the specific dynamic disk to basic disk.Because partition wizard cannot convert any dynamic volume type expect the simple and mirror volume."

    I'm not sure. I've never seen that message before. It is because of the spanned volume. You need to Break the spanned volume (without losing data) before you can convert.

    If you right click on the spanned volume, is there an option to "Break" it?

    I've asked for more help.

    I have not been able to find anything that will allow you to break a spanned volume without losing your data.

    It seems (to me) that this is your best (only?) option:

    • Backup your data from spanned volume(s) D: to another drive (external or another physical hard disk)
    • Once you have secured your data, then REMOVE (not Delete!) the spanned volume (this will delete all data in the volume!)
    • Once the spanned volume is removed then you should be able to convert with Partition Wizard without losing the OS on C:

    EDIT: If you have PROGRAMS installed on D: then you may still be able to restore these installations from the backup on the new basic disk labeled D: as long as you make the conversion, create the basic volume D:, and copy everything back into D: before starting Windows.
    If Windows starts and finds the programs missing then you would probably need to reinstall them all.

    Look at your screenshot in the first post. In the lower portion of Disk Management it graphically shows the Volume setup. The first D: volume is 200.20 GB. The second is 206.97 GB. That totals 407.17 GB.

    Now look at the top section of DM. It shows one D: volume of 407.17 GB. This proves that the two volumes are combined and treated as one spanned volume by the OS.
