Using Your NAS System 45Shrinking a VolumeYou can decrease the space used by primary partitions and logical drives byshrinking them into adjacent, contiguous space on the same disk. Forexample, if you discover that you need an additional partition but do not haveadditional disks, you can shrink the existing partition from the end of thevolume to create new un-allocated space that can then be used for a newpartition.For shrinking a volume:1 In Disk Manager, right-click the Basic Volume you want to shrink.2 Click Shrink Volume….3 Follow the instructions on your screen.NOTE: You can only shrink basic volumes that have no file system or use the NTFSfile system.Additional Considerations• When you shrink a partition, unmovable files (for example, the page file orthe shadow copy storage area) are not automatically relocated and youcannot decrease the allocated space beyond the point where theunmovable files are located.• If the number of bad clusters detected by dynamic bad-cluster remappingis too high, you cannot shrink the partition. If this occurs, you shouldconsider moving the data and replacing the disk.• Do not use a block-level copy to transfer the data. The block-level copyalso copies the bad sector table and the new disk treats the same sectors asbad even though they are normal.• You can shrink primary partitions and logical drives on raw partitions(those without a file system) or partitions using the NTFS file system.
