我在 Sony VIAO E 系列 VPCEH16EN、4GB RAM、320 GB HDD、Intel Core i3-2310M 处理器 2.10GHz 上安装了 Ubuntu 12.10。它与 Windows7 一起双启动。
我发现系统响应非常慢，任何视频在播放过程中都会卡住。你能帮我找出瓶颈在哪里吗？以下是hdparm和的输出smartctl：

磁盘的 SMART 数据显示您的硬盘出现故障。我会备份磁盘中可能存在的重要信息并尽快更换。
一切类型： 失败前警告应该明确指出，除了104、105、106、107 和 108报告中的错误smartctl。
palimpsest您还可以使用( )检查硬盘状况（由 SMART 数据显示）Disk Utility并在那里检查状态
