You should rather disable the drive in BIOS, otherwise Windows might recognize it, too, and destroy it.
You need Win2000 or WinXP for WinUAE to work with the HD.
Perhaps you'd better choose the other way: connect the PC HD to the Amiga. It's less painful and less dangerous and perhaps even faster because WinUAE is quite slow on direct disk access. Get FAT95 from Aminet to read and write PC HDs on AmigaOS.
