Error Message

 Error V-76-58645-260: "Either no space is available on your dynamic disks or the configuration is not valid to complete this operation."

Because of the contiguous requirement for the Boot or System partitions, the region to grow must start from the end of the partition. For example, if the track alignment offset is set to 64, then all tracks must start at an offset divisible by 64.  If the partition ends at sector 17655435, the sectors to grow the partition start at 17655435 +1, which is not track aligned.  Therefore with track alignment enabled, the requirements to satisfy both track alignment and contiguous sector use cannot be met and the operation fails.

(17655435 +1)/ 64 = 275866.1875 which is not a whole number, therefore the expanded space will not start on a track boundary.

For this operation, temporarily disable  track alignment, and then grow the partition to the intended size.

Note: There is a difference between track alignment and cylinder alignment.  Cylinder alignment is legacy, and aligns on the virtual boundary.  Track alignment tries to allocate a region of the disk aligned with physical I/O boundary.  These are usually multiple of 64 and are vendor specific. boot and System partitions have to be contiguous and cylinder aligned. 

Applies To

Track alignment is enabled.

The Boot or System partition being expanded does not end on a track boundary.
