请问，在安全模式下面可以使用外接移动硬盘吗？谢谢。

另外，安全模式下，一般哪些硬件可以用，哪些硬件不可以用呢？是不是外接的都不可以用呢？

Windows XP help and support center:

safe mode:

Starts using only basic files and drivers (mouse, except serial mice; monitor; keyboard; mass storage; base video; default system services; and no network connections). If your computer does not start successfully using safe mode, you might need to use the Recovery Console feature to repair your system.
