Unraveling the Dilemma: SSD not Showing Full Capacity in Windows 10/11

Understanding the Problem

Picture this - you've invested in a high-capacity SSD, only to find that Windows reports a different, often lesser, storage capacity. This discrepancy between the actual SSD capacity and what Windows recognizes can stem from various sources.

Potential Causes

Unallocated Space - Unallocated space on the SSD, not assigned to any partition, can lead to a perceived reduction in capacity.

File System Overhead - The file system structure, such as NTFS, introduces overhead, consuming some of the SSD's capacity for system files.

Hidden Partitions - Hidden partitions created during the Windows installation process might not be visible but still occupy space.
