VDS_E_REQUIRES_CONTIGUOUS_DISK_SPACE

VDS_E_REQUIRES_CONTIGUOUS_DISK_SPACE means the operation needs one uninterrupted unallocated range on a disk. Total free capacity may be sufficient, but it is split between existing partitions or extents.

What to check

Inspect offsets and sizes of all partitions on the target disk.
Do not confuse free space inside a volume with contiguous unallocated disk space.
Plan any relocation, shrink, or partition removal carefully and back up affected data first.
