回复：我的XP突然不能启动。在RECOVERY CONSOLE下查了，硬盘，没有问题。

I connected this bad disk 160G as a slave to old machine with win2000. The bad disk(160G) was claimed as a corrupted disk. And later, I moved old disk (20G) to my dell and used it as master, bad disk(160G) as slave, then the bad disk(160G) became readable and I recovered my files. It looks like xp has an upgraded format to disk against win 2000.
Anyway I have an awkward system now, 20G master with 160G slave. What can I do with that?
