[問題] vmware server 安裝FreeBSD 並接取usb disk問題
實體機為windowx XP with SP3, 虛擬軟體為vmware server 2,
虛擬環境為 cpu兩顆, ram 1024M, disk 2顆scsi disk, 1G與8G, 並開啟usb功能.
外接硬碟盒為 雙城 e-DATA II 3500, 內部介面為SATA可接兩顆硬碟,
外部介面有eSTATA與USB, 目前是接USB
vmware server的usb功能為可選擇接取實體機上幾乎所有USB裝置,
因為想省掉虛擬層的效能消耗, 所以將外接硬碟盒接USB port並使用
vmware server的usb功能接進裡面的OS, 也就是FreeBSD.
FreeBSD有抓到該外接盒與硬碟, 甚至是外接盒的轉接晶片都有抓到,
硬碟型號也都有取得, 但系統要access硬碟時, console就會出現錯誤訊息,
/var/log/messages也會紀錄到, 且此時硬碟I/O就會卡住一下,
若繼續存取則會造成資料損毀的狀況.
以下為/var/run/dmesg.boot的節錄訊息

很久之前有找到用camcontrol可以調整修正此問題, 但忘了保存該設定方式即重灌,
現在怎樣google也找不到解決方式了, 希望有過經驗的人能給予指引, 若有資訊不足
的部分也請說明, 我再補上, 感激不盡.
