HDD Capacity Restore is a freeware tool that allows you to restore full factory capacity of any hard drive. It recovers LBA48 modes, DCO and HPA.

It does everything automatically: it extracts the factory capacity; then it restores the factory LBA48, HPA and DCO settings. We strongly recommend to re-power your computer before running this tool. That means completely power off your computer; then power on, start Windows and run the tool.
