There are two ways to expand a disk without affecting the original disk data:

First, use the functions of operating systems such as win7 and Windows2008 to operate.

1. Right-click [My Computer] and select [Management] to open [Computer Management];

2. In Computer Management, expand and select Computer Management (Local) → Storage → Disk Management, right-click the disk to be adjusted and select Compress Volume until the operation is completed.

3. Right-click the disk to be adjusted, select [Extended Volume], and select the remaining space, which can be allocated to other partitions to complete disk expansion.

Second, use DiskGenius hard disk partition and data recovery tools to operate.

1, according to experience, defragment and repair the disk first, and then expand the disk, otherwise the operation may fail. For example, chkdsk e: /f /x

2. Use DiskGenius tool to adjust disk capacity, and you can open help in the tool operation interface.
