这个东东先驱们早有说过，从上面的PTM File Id = B1流程测试模块文件ID是B1,PTM Test Id = 4E0流程测试模块测试ID是4E0，也就是WDR软件的中文版的伺服校验按钮，英文版是PS Cal Test这个按扭。有时我们出盘会全盘叹号，（自校日志绝对不可以清）有时清译码再重建P表不能解决的，可以清译码-重启-PS Cal Test-完成后重启-重建P表试下。这个PS 是个缩写，不确定是不是 Positioning signal定位信号的意思，还是phase shift相位偏移的意思或其它。做了它后flash的4F会改变，4F各个软件说法不一，我本人更原接受宏代码版本这个说法，因为其专利文件也常提到宏脚本，修正后解码器才能正确识别。当然这纯属我个人见解，或许就是个谬论。 学习了，感谢楼主的分享。 科技再改变了，这些是不是已经不适应新的硬盘家族了！？ anpengcy 发表于 2017-7-8 00:03
科技再改变了，这些是不是已经不适应新的硬盘家族了！？
这个说法不无道理，随着技术的改进须与时俱进。就像钓鱼一样，其实大家不是注重得了几条鱼，而是过程的一种快乐。维修亦然，这过程是我们对未知孜孜不倦的追求，再分享我们的收获，使可以相互借鉴，产生新理论、甚至新技术，我们也无愧于这个时代，因为我们把知道的已贡献了! 科技再改变了，这些是不是已经不适应新的硬盘家族了 这是什么神器可以读出硬盘模块的程序翻译白话文的？ 楼主精神可嘉。现在西数被放的差不多了。转希捷把。 感谢分享，向你学习 路过，赚点儿（1：（1：
