U盘之家

 注意：此工具为命令行下运行(开始-运行-执行cmd进入命令行) 优盘之家

下载包含有32位和64位2个版本的程序。
命令行工具，可能很多人会不习惯。其实建立一个快捷方式就很容易搞定了。

使用方法：确认你的 U 盘盘符，然后在 ‘命令提示符“ （开始 > 运行 > CMD > 回车）使用 RemoveDrive g: -l 即可，参数 -l 是重复卸载直到成功。其中的参数 -s 很牛逼，它会在卸载 U 盘之后删除程序自身，真正做到了舍己为人呐。 U盘之家

Usage:
RemoveDrive DriveSpec [-l][-h][-b][-i][-s][-w:nnnn]
                     
DriveSpec  is the drive to remove, e.g. U: or an NTFS mountpoint as "C:\CardReader\Multi Reader SD"
           or . for the current drive
           or \ for the drive of the RemoveDrive.exe
           or a volume name like \\?\Volume{433619ed-c6ea-11d9-a3b2-806d6172696f}
           or a kernel name like \Device\HarddiskVolume2 (Volume)

[-L]       loop until success
[-e]       try to dismount and eject if the removal fails
[-h]       show open handles (admin rights required, exprimental, may freeze!)
[-h:X]     show open handles on a different drive (e.g. a TrueCrypt volume whose container is on the drive to remove)
[-w:nnnn]  wait nnnn milliseconds before close
[-s]       self delete removedrive.exe
