    Is there any way to merge the two "K" volumes / partitions into one?
    Disk 0 originally looked like Disk 1 (they're broken mirrors actually, with Disk 1 left unperturbed).
    I wanted to move my data off the C:\ partition and onto a new K:\ partition.
    So, I resized C:\, created a K:\ partition for data away from the OS partition, and then moved some data over. I couldn't move all the data at once because there wasn't enough space in the new K:\ partition. But, I moved about half of it over to K:\ from C:\. Then, I shrank the C:\ volume again. Then, I extended the K:\ volume to take up the newly unallocated space and was planning on moving the rest of the data from C:\ over, but then I noticed this weird partition structure with the 2 simple K volumes. Any ideas what happened here or how to clean up the 2 K's into one? Thank you.

    From your image it shows that your partition K: is simple volume on dynamic disk, and it is split into two slices, this is the feature of dynamic volumes ( it could make volumes become discrete, like your situation), you could not merge them into one volume, because it is a single volume already (not two volumes, just two slices. You extended a simple volume into another slice of the disc, so now Disk Management is diagrammatically showing you the two slices of the disc that, when concatenated, make up the whole of the single volume. And because of the way that you've done this, the slices are in reverse order. The first (458.38GB) piece on the disc is actually the second part of the actual volume.
    In your situation you could only backup your data on K: volume then delete it and create a new single with one slice then back your data. Or you could use Dynamic Disk Converter, to convert it back to basic disk.
    Note: if you use that tool, you should use the second method to clone your volume K: to a basic disk, then the two slices will be "merged" into one.

    Thank you so much, spunk. For some reason the option to convert to basic disk is greyed out.

    I copied the K:\ data to a new (basic) disk and it is now a single slice volume-- nice! Question: before I go to restore the clone to the original disk, should I convert the original disk to basic (which is now an option since the multislice volume is deleted)?

    This is now fixed!
