The "Grow-Only" Virtual Disk Trap — Reclaiming 150 GB in One Passhttps://blog.lynxflow.co/en/posts/wsl-docker-vhdx-shrink-reclaim-disk/Thu, 10 Sep 2026 09:00:00 +0800https://blog.lynxflow.co/en/posts/wsl-docker-vhdx-shrink-reclaim-disk/The numbers didn’t add up During a routine disk health check, I hit a discrepancy: Windows showed the C drive at 949 GB with 652 GB used — in the red. But df -h / inside WSL (Ubuntu) reported only 135 GB used. That left 500+ GB unaccounted for. Common sense says deleting a file in Linux should shrink usage on the Windows side too — I’d deleted 62 GB of video output the night before, so the C drive should have loosened up considerably. It didn’t budge.
