我正在嘗試確定是否需要更換 2019 年 12 月購買的 2018 Mac Mini（512 GB SSD，16 GB RAM）。當我運行急救時，我不斷收到以下錯誤。我在恢復模式下從下往上修復它，首先是卷，然後是容器，它說它已修復並且磁碟看起來正常，但幾個小時後，當我再次運行急救時，錯誤又回來了：

我遇到了類似的錯誤，並對此進行了一些研究，我想我可以在這裡分享。一個重要的區別是，這與格式化為 APFS 的磁碟機有關。請謹慎遵循您發現的可能較舊且並非特定於 APFS 驅動器的建議。
- 一些參考文獻（最近）指出 APFS 驅動器需要在容器上運行急救，而不是在磁碟區上。這顯然需要在系統未安裝時完成，例如在恢復模式下（啟動時使用命令 R）。關聯
- 一位用戶表示，他在運行「急救」之前手動卸載了驅動器，並聲稱「磁碟工具」有時無法執行此操作。關聯
- 同一 MacRumors 討論中的另一位用戶（擁有 68000 個身份點）表示，他不僅對主驅動器的「所有實例」運行了急救，還禁用了時間機器，然後使用終端刪除了所有本地快照。關聯
- 此 Apple 支援文件討論了檢視和刪除 APFS 快照。關聯
驅動器運作狀況與資料損壞
- 我看到的與此相關的問題似乎主要與資料損壞有關，而不是由於驅動器故障，儘管錯誤訊息看起來相當不祥。也就是說，即使您最近有備份，重新格式化磁碟機來解決損壞問題並非無足輕重。
- 這篇文章指的是智慧工具作為免費的命令列 APFS 磁碟監控/評估解決方案。關聯
- 另一篇文章提到了一個免費的基於 GUI 的 SSD 監視器，稱為 SSDReporter。關聯

答案2
我沒有更換 2018 年 Mac Mini。看來這可能是 MacOS 或急救中的錯誤，因為我不再收到錯誤訊息。
