苏州本地某台资企业送修一块笔记本硬盘希捷ST500LM000 SSHD需要进行二次恢复，客户描述硬盘损坏后被公司IT拿出来接到移动硬盘盒里读取通电不转，就找了一家修电脑的说电路板坏了肯定可以100%恢复里面的数据。修复了一个多星期更换了好三块电路板没能解决问题。客户经朋友介绍将硬盘送至本公司进行二次恢复，盘首工程师接到硬盘后在3块电路板中找到客户原始的ROM芯片，（因为前面被修过也不知道原ROM芯片在哪块是电路板上,幸运的是ROM芯片没有弄丢），由于没法确定哪块是原始的PCB电路板，只能将ROM芯片读取出来写入到其它电路板上进行ROM适配才成功。经过1个多小时的镜像 成功恢复出客户的全部数据。
