ext4-fs:幾何錯誤:塊數超過設備大小

  • September 17, 2018

我有 2TB 磁碟,我在筆記本中使用。該磁碟被格式化為 ext4 並且在筆記本上執行良好,但是當我將它附加到桌面時(通過 sata-usb 適配器),由於以下錯誤,我無法安裝它:

從桌面:

我的問題是:為什麼一台電腦在磁碟上顯示的扇區數量與另一台電腦不同?我檢查了壞塊,沒有找到。

這發生在有故障的 USB 介面適配器上。適配器出現故障的可能原因:

  • 適配器太舊
  • 便宜的適配器
  • 壞的適配器韌體

隨著高級格式驅動器的出現,這些錯誤變得更加頻繁。

一些適配器嘗試“轉換”AF 驅動器互動,以便模擬傳統格式驅動器。

這意味著您可以:

  1. 使用 USB 適配器格式化驅動器,然後在兩台電腦上繼續使用 USB 適配器
  2. 獲得更好的 USB 適配器,這樣您就不必格式化您的驅動器。
  3. 在兩台電腦上使用內部 SATA 連接器。

格式化將破壞驅動器上的所有數據。
