ATrom的版本有两个，333和339，你只需要其中一个的就行了。看哪个合适就行。你就用那个能跑起SF的那个ATROM版本就行了。CERT TEST板就是写入了CTROM的板子，没啥别的了。你那个已经写进了CTROM的板就已经可以了。至于U6DLE所用到的回写和备份的命令，我都放在文档里了，你看一下就看到了。
我这几天也正在研究U6，针对你其中几点说下我这几天来研究U6SF的想法：
不用备份ATROM，写他给的就行。甚至我几个3.19的SF后回写网上别人给的3.19的AT ROM全部失败，成了GC110/SVC Mismath，我后来发现只有3.19版的才这样，估计是319.FLS文件本身不对，试着写3.39的AT ROM后显示02模块不对，再回写339的02模块就认盘了，版本成了339，其它模块都没动，然后就可跑N40了，刚才这样已试成功了两个了，其它几个后面也可如此试一下。
关于换板，我也发现不用换ROM，任意版本可随意换，因为换上后写入盘体相应版本的SERT ROM（SF前）和AT ROM（SF后）就行了，我换了好几块全部都成功了。所以你的CERT板应该没什么要求，只要是好的就行。ROM，备份我也不会，我一个80G的没相应版本的AT ROM，我就用个40G的板来开完SF再换回原板接着做N40，不过再扫还有坏道，不知何处不对，还待我研究。
U6DLE的应用本版有不少说明，你可以往前找找。
一般好的盘16小时左右，差的2－3天，我发现有的盘会自动停，有的则电机一直空转，还不知道是什么原因。
个人感觉U6最好一直挂串口上看着，看它最后跑到了哪里停下的，因为不象鱼盘从2做起时可通过NO LOG来判断一些情况，我试过用D4也看不出什么的，因为U6在SF时没有格式化SA区，所以老的记录全部都在的。不过我现在开了十来个，只好大部分挂独立电源不看，那些自动停的一般都是正常的，直接回写ATA ROM并跑40就行了。想挂独立电源的，要N4指令完成后打入W指令（也是在T级下，把内存里的信息写入扇区），之后任意一步都能停，甚至直接从04停了也行，我试过很多块了。

这个差的盘磁头常会复位，HEAD MASK几次后又会认出并继续，是不是和板没接触好啊？39、31等扫坏扇区的时间都是好盘的三倍左右，而且我用E39之类的看过扫出来的坏扇区记录特别多，可能盘体要报废了。
固件我也不会查，或者能正常备份读出的就算好的吧。我反正是没查过，都是SF结束后用VCR擦和读各一次，G表都没出来新增的，速度也正常并均匀就算好了。
给你一个我的SF全程记录看看，可参考一下，流程可能和你的有些不同，因为用的是别的流程。

关于U6跑SF，有几点是需要注意的，网上有提供的ATROM和CERTROM我不知道能不能用，我也没试过，我自己有我的一套文件。
首先U6跑SF根本就不需要制作CERT板，只要你有ATROM就可以了，ATROM在U6DLE中所对应的模块就是01号，但ATROM不能用U6DLE备份的原盘模块回写，这样有可能会把板写死，我自己有一整套U6的ATROM，有需要的可以向我索取，我的绝不是网上流传的那种，我不会收费的，CERTROM和OVL流程文件通常就只有两种了，这两种在使用中是有原则的，不是所有的不同固件版本的硬盘都可以一通乱写的，请注意了，要分清楚，CERTROM和OVL流程文件分333和339两种，339的CERTROM可以写319 339 399的盘，333的CERTROM可以写331 334 533的盘，如果你的ATROM不是很全的话，也可以跟CERTROM一样的代换原则。有不懂的可以联系我QQ253320592
