為什麼在 vista 64bit sp 1 + ghost v.14 做 disk to disk 會出現這種情況

第一次時出現訊息

-Error EC8F17B3: Cannot complete copying of xxxx (F:\) drive.
--Invalid destination.
---Invalid destination.

另一隻 harddisk 又出現這種訊息

-Error EC8F17B3: Cannot complete copying of xxx (G:\) drive.
--Cannot copy source drive to destination location.
---Error E7C3001F: Volume '\\?\Volume{60091e79-9db8-11dd-af18-806e6f6e6963}\' cannot be dismounted.
---Cannot copy source drive to destination location.
----Error E7C3001F: Volume '\\?\Volume{60091e79-9db8-11dd-af18-806e6f6e6963}\' cannot be dismounted.
