How to change partitions in Windows Server 2012!

2025/9/18 Edited to

... Read moreWindows Server 2012のディスク管理では、特にCドライブの拡張でつまずくことがあります。例えば、Dドライブを縮小しても未割り当て領域がCドライブ直後に配置されていなければ、『ボリュームの拡張』がグレーアウトして使えないことが多いです。そんな時におすすめしたいのが、Partition Assistant Server版というツールです。 私もサーバー管理の経験で、容量不足が深刻になった際にこのツールに助けられました。操作は非常に直感的で、拡張したいパーティションを右クリックし、「パーティションのリサイズ/移動」を選択するだけです。未割り当て領域を動かして一列に揃えることで、Cドライブの容量をスムーズに増やせます。 また、回復パーティションやEFIシステムパーティションの扱いには特に注意が必要です。標準のWindowsツールではこれらのパーティションの操作が制限されてしまうため、専用ツールの使用が推奨されます。Partition Assistantはこうした特殊パーティションの管理にも対応しており、サーバーの安定運用に役立ちました。 さらに、ツール導入に際しては安全に作業するために、バックアップを忘れずに行うことを強くおすすめします。実際のところ、私自身もバックアップを取った上で操作したため、万が一のトラブルも回避できました。これからWindows Server 2012を使ってパーティション操作を検討している方には、この方法で効率よくサーバー容量を拡張してほしいです。 このように、パーティション管理における『未割り当て領域の移動』や『拡張できない回復パーティションの対応』など、手順を押さえることでWindows Server 2012の制約を乗り越えられます。ぜひ参考にしてみてください!
