Cloned to a new, larger SSD, need help fixing partition to expand C drive

Optimizing Drive Partitions After Cloning to a Larger SSD: Troubleshooting and Free Alternatives

Upgrading your storage drive is an excellent way to enhance system performance and expand capacity. However, post-cloning, managing partition sizes—particularly expanding the C drive—can sometimes pose challenges. If you’ve recently cloned your Windows drive to a larger SSD and are experiencing issues adjusting your partitions, this guide will help clarify potential solutions and suggest free, reliable tools to manage your disk partitions effectively.

Understanding the Issue

After cloning your existing drive to a bigger SSD, you may find that the C drive partition does not automatically expand to utilize the extra space. This is common because most cloning operations copy the exact partition structure, leaving unallocated space unused unless manually adjusted.

In your case, the attempts to resize or extend the partition using partition management tools have encountered obstacles. Specifically:

MiniTool Partition Wizard: Reports that it cannot operate on the active drive and prompts for a restart to change the drive’s partition. However, after restarting, it states that the configuration has changed and cannot proceed, returning you to Windows with no modifications.
EaseUS Partition Tool: Is inaccessible due to licensing restrictions unless you purchase a license, which you consider unnecessary for future use.

Why the Problems Occur

Several factors can contribute to these issues:

Drive being marked as active or system partition constraints: Some tools require the drive to be unmounted or not in use.
Partition states or system lock: Windows or the tool might lock certain partitions.
Software limitations: Free versions of partition tools may restrict certain operations.
System driver or BIOS issues: Rare, but can interfere with disk management operations.

Proposed Solutions

1. Use Disk Management in Windows

Access via Disk Management (Right-click Start menu -> Disk Management).
Locate the unallocated space adjacent to the C drive.
Right-click on the C partition and select “Extend Volume” to add the unallocated space.
Note: If “Extend Volume” is grayed out, it indicates the unallocated space is not directly contiguous or that certain system constraints prevent extension.

2. Use a Bootable Partition Management Tool

Some issues with performing operations within Windows can be bypassed by booting from a dedicated environment:
