Shrinking a Volume

You can decrease the space used by primary partitions and logical drives by

shrinking them into adjacent, contiguous space on the same disk. For

example, if you discover that you need an additional partition but do not have

additional disks, you can shrink the existing partition from the end of the

volume to create new un-allocated space that can then be used for a new

partition.

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 NTFS

file system.

Additional Considerations

•

When you shrink a partition, unmovable files (for example, the page file or

the shadow copy storage area) are not automatically relocated and you

cannot decrease the allocated space beyond the point where the

unmovable files are located.

•

If the number of bad clusters detected by dynamic bad-cluster remapping

is too high, you cannot shrink the partition. If this occurs, you should

consider moving the data and replacing the disk.

•

Do not use a block-level copy to transfer the data. The block-level copy

also copies the bad sector table and the new disk treats the same sectors as

bad 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.
