效率源日立硬盘(Hitachi)解密攻略在硬盘维修和数据恢复工作中,经常会遇到被加密的硬盘。
日立专修支持5410,5432等共39种硬盘解密,本文将介绍日立硬盘解密步骤以及注意事项。
提示:由于NVRAM信息在日立/IBM硬盘数据恢复中非常重要,所以在将硬盘转入到安全模式之后,请先使用“NVRAM操作” > “读取NVRAM”功能对NVRAM 内容进行备份。
加密的硬盘在装入之后会出现如下画面:日立硬盘不同于其它硬盘,加密是对固件区和数据区同时进行。
所以加密的日立硬盘固件和数据都无法访问,因此日立专修没有其它专修具有的一键解密功能。
这时,需要将硬盘转到厂家模式,然后用C区的密码模块回写修复A区模块。
这就是日立硬盘的解密原理。
因为无法从硬盘装入获取资源信息,这时需要选择相应的资源文件从文件装入硬盘信息,或者可以直接选择硬盘系列,程序会自动装入集成的资源文件。
装入资源初始化终端后,接下来要将硬盘转入厂家模式,操作步骤如下:断电,设置硬盘跳线为安全模式,然后做A区和C区转换。
对于不同接口的盘,安全模式跳线有不同方式,下图是各种硬盘跳线方式:2.5寸PATA硬盘跳线方式:注意:上图是936转接卡跳线方式,对于916转接卡,方向是相反的。
2.5寸SATA需要先将电路板取下,再将其单独接上终端盒,如下图:ATCS和ATDA是日立过渡型硬盘,其跳线方式不同于其它盘,需要使用RC跳线,如下图:3.5寸PATA盘跳线方式:,主盘模式;,安全模式。
3.5寸SATA盘,需要将电路板和盘体分离, 如下图:设置好安全模式以后,开电,点击,提示点击“OK”,稍后会有提示点击“OK”后,断电,移去跳线或者连接电路板或者安全模式跳回主盘模式。
然后,开电,这时硬盘就进入了厂家模式,可以访问固件了。
将工作组设置为C组,读取密码模块。
密码模块一般有三种:IECS,SECI 和PSW。
将工作组设置为A组回写备份的C组密码模块,注意要选对路径回写完之后,同之前的操作一样,再做一次A区和C区转换,将硬盘转回用户模式。
SATA RAID独立芯片及产品详解众所周知,RAID早已成了服务器技术(产品)中重要的组成部分。

几种用于IGBT驱动的集成芯片2. 1 TLP250(TOSHIBA公司生产)在一般较低性能的三相电压源逆变器中,各种与电流相关的性能控制,通过检测直流母线上流入逆变桥的直流电流即可,如变频器中的自动转矩补偿、转差率补偿等。
同时,这一检测结果也可以用来完成对逆变单元中IGBT实现过流保护等功能。
因此在这种逆变器中,对IGBT驱动电路的要求相对比较简单,成本也比较低。
这种类型的驱动芯片主要有东芝公司生产的TLP250,夏普公司生产的PC923等等。
这里主要针对TLP250做一介绍。
TLP250包含一个GaAlAs光发射二极管和一个集成光探测器,8脚双列封装结构。
适合于IGBT或电力MOSFET栅极驱动电路。
图2为TLP250的内部结构简图,表1给出了其工作时的真值表。
TLP250的典型特征如下:1)输入阈值电流(IF):5 mA(最大);2)电源电流(ICC):11 mA(最大);3)电源电压(VCC):10~35 V;4)输出电流(IO):± 0.5 A(最小);5)开关时间(tPLH /tPHL):0.5 μ s(最大);6)隔离电压:2500 Vpms(最小)。
表2给出了TLP250的开关特性,表3给出了TLP250的推荐工作条件。
注:使用TLP250时应在管脚8和5间连接一个0.1 μ F的陶瓷电容来稳定高增益线性放大器的工作,提供的旁路作用失效会损坏开关性能,电容和光耦之间的引线长度不应超过 1 cm。
图3和图4给出了TLP250的两种典型的应用电路。
在图4中,TR1和TR2的选取与用于IGBT驱动的栅极电阻有直接的关系,例如,电源电压为24V时,TR1和TR2的Icmax≥ 24/Rg。
图5给出了TLP250驱动IGBT时,1 200 V/200 A的IGBT上电流的实验波形(50 A/10 μ s)。
可以看出,由于TLP250不具备过流保护功能,当IGBT过流时,通过控制信号关断IGBT,IGBT中电流的下降很陡,且有一个反向的冲击。
硬盘拆解图解1TB Seagate ST31000333AS这块绿色电路版,由SATA接头、电源接头组成的板子称为印刷回路板,简称PCB。
PCB内含电路零组件。
而黑色铝质外壳内部组件称为磁头和硬盘组件,通称为HDA。
而铝质外壳则称为硬盘基底。
现在拆卸PCB电路板并翻到反面,检视反面的电子零组件。
MCU控制器硬盘PCB上最大控制器为MCU (Micro Controller Unit),MCU主要功能:1、计算读写通道A/D,D/A2、掌控全盘硬盘运作状况。
3、MCU 另担当的Protocol 与控制器间的转换。
DDR DRAMDDR DRAM 32MB ,实际上32MB Cache 部份会被硬盘挪用放入硬盘运作程序。
前言已叙述,硬盘如同一个embedded system 。
需要加载OS运作。
VCM控制器下一个芯片是V oice Coil Motor controller,通称VCM控制器。
这是PCB板上最耗电的芯片,VCM控制器控制电机马达的转动及磁头移动及定位,VCM控制器可在高达工作温度Flash芯片Flash芯片储存部分的硬盘韧体与模块在盘片上位置DATA ,当你通电启动硬盘时,MCU芯片会读取Flash芯片内的数据到内存内并且开始编码。
如果缺少了这样的步骤,硬盘无法运转。
有时候,某些厂牌的硬盘PCB板上并没有Flash芯片,这表示原本Flash 芯片内的数据已存在MCU芯片内了。
震动传感器震动传感器可以感应硬盘多余的震动并且传送讯号给VCM控制器,VCM控制器接受讯号以后马上停止并复位磁头,在某些情况下,甚至会停止盘片转动,这个理论上会保护硬盘免于受损,但是实际上并无法达成保护的目的,所以请好好保护硬盘,别摔落、碰撞!在某些硬盘中,震动传感器可以感测轻微振动,而VCM控制器可以藉由震动传感器传送的讯号调整磁头的运动,这样的硬盘通常都会配有两组以上的震动传感器。
二级体另外一个保护的零组件是瞬态电压抑制二极管(Transient Voltage Suppression diode)或简称为TVS二极管。
几种用于IGBT驱动的集成芯片2. 1 TLP250(TOSHIBA公司生产)在一般较低性能的三相电压源逆变器中,各种与电流相关的性能控制,通过检测直流母线上流入逆变桥的直流电流即可,如变频器中的自动转矩补偿、转差率补偿等。

表2给出了TLP250的开关特性,表3给出了TLP250的推荐工作条件。
注:使用TLP250时应在管脚8和5间连接一个0.1 μ F的陶瓷电容来稳定高增益线性放大器的工作,提供的旁路作用失效会损坏开关性能,电容和光耦之间的引线长度不应超过1 cm。
图3和图4给出了TLP250的两种典型的应用电路。
在图4中,TR1和TR2的选取与用于IGBT驱动的栅极电阻有直接的关系,例如,电源电压为24V时,TR1和TR2的Icmax≥ 24/Rg。
图5给出了TLP250驱动IGBT时,1 200 V/200 A的IGBT上电流的实验波形(50 A/10 μ s)。
