Migrate OS to SSD/HDD

Extend system drive and make Windows system run faster? Replace your old HDD with new SSD? Clone system to HDD/SSD for backup? EaseUS Partition Master works well to migrate OS to SSD/HDD.

This easy disk partition software can help you transfer data, Windows operating system and configurations on system boot partitions to new SSD/HDD without Windows reinstallation. Before the move, make sure there is enough unused disk space to install the system in case of data overwriting. After system transfer is done, you can directly boot up the Windows system from the target disk.

Format Hard Drive/Partition?

If you install a new hard drive, create a new partition, or wipe your drive/partition clean now, you'll end up formatting your drive. Formatting will check the disk for errors, and prepare it for use. If a drive stores crucial data, please back up your data at first before the operation. EaseUS Partition Master only takes you a few minutes to get your disk/partition properly formatted.
