Why is the Shrink Volume button disabled?

Question

Hard disks

Hello. The Shrink Volume button is disabled in Disk Management. It is inactive only for flash drives. I have 5 flash drives and on all flash drives this button is inactive. It is possible to shrink a volume on a hard drive.

Answer 1

Because Windows does not support full repartitioning of flash drives. If the flash drive is partitioned, then it mounts only the first partition, ignoring the rest. Maybe they fixed it in Windows 10, haven't checked.

Answer 2

Shrink a volume is a change in the size of the partition on which this volume is located.
Flash drives do not support changing the volume from the interface.
Try it from diskpart - it's not a fact about shrink, but it will work out and create the desired size.
