+libldm is a tool and library for
+managing Microsoft Windows Dynamic Disks.
+which use Microsoft's LDM metadata. It can inspect them
+and also create and remove device-mapper block devices
+which can be mounted.
+
+Although a filesystem can be mounted read-write
+and its contents modified, ldmtool is not able to
+modify the LDM metadata itself. That is, it cannot
+create, remove or edit dynamic disks.
+
+It is also not able to mount RAID5 volumes which
+have a partition missing, although it can mount mirrored
+volumes with a partition missing. However,
+mounting a volume with a missing partition is not recommended,
+as ldmtool does not update the LDM metadata in any way.
+This means Windows will have no way to determine that the partitions
+are not synchronised when it subsequently mounted,
+which may result in corruption.
