這幾天用 "PowerQuest PartitionInfo 8.0" 檢查了一下, 以下為有問題的 Disk:
===========================================================================================================

正常的 Disk 其 ECyl ( End Cylinders) 應該為 Cylinders 之值減 1,
但是此 Disk Total Cylinders 為 16709 (PM8), 但 Partition table 之 ECyl 卻大於
16709. 是不是只要將此 ECyl 修正即有可能讀到原有的資料! (SPFDisk 應該可以使用)
不知道有沒有可備份 Partition 之軟體. 想在動手之前先備份一下 Partition.
