更新了定制版SSD戴尔固件，用Parted Magic做SE是否有效？
如题，浴室好像喜欢使用HDAT2，但是用HDAT2 需要拔数据线，造成C7 UDMA CRC错误率有17个计数，看起来不爽，而用PQ就不会有C7错误，但是搞不清楚这两个是否都是一样的效果，且我还用了“增强型”SE。下载的最新版PQ20160712版，选的第一个 ATA Secure Erase，然后点击SLEEP休眠并自动唤醒，然后勾选要SE的SSD并选中后面的“Enhanced Secure Erase”，确认之后SE过程几乎是秒射！？ 不到10秒？？？太快了吧？！而之前用易驱线SE一个250GB的SSD需要22分钟才能完成
上面的日志显示成功擦除：

懒得麻烦嘛，万一出问题还得从新装系统，软件

是的，有点强迫症，喜欢追求完美，但是哪来的完美？

{:1_465:}怪得不有C7错误啊，OMG
同样遇到了，我在笔记本上se的，所以用的pm的休眠唤醒。
预计se时间是6min，实际不到1min就结束了
