(1) If your hard disc is mainly used for storing data, don’t overwrite any firmware module or a group of modules (if you have experience, you can overwrite some of them). Data in the hard disc is much more important than its performance sometimes! What we should do is to recover “the four modules” in module recovery, having loaded the correct LDR and RAM in the safe mode (the firmware matching is very important!)
(2) If you just only want to repair the hard disk, it is easy to handle to compare! How do you write firmware on such kind of hard disc (with MT common fault)? Overwrite some module? Or overwrite a group of modules? Or overwrite all of them? In fact, it is not necessary for us to overwrite all of the modules in many cases. I think we should know about some primary knowledge of modules:
1E 30 33 18 1B——these modules must not be changed when you write a firmware!
1E : whole disk adapting
30 : compiler
33 : speed module
18 : G- LIST
1B : P-LIST
It is important, however, these modules are often ignored!
Many friends mention this kind of situation: the hard disc goes round very slowly after Maxtor firmware is revived by PC3K; there are a lot of red blocks and green blocks even bad tracks when it is detected with mhdd. If hard disc failure is due to corruption of the firmware zone, hard disc drive will suffer SUDDEN DEATH during the course of using normally. Even if there are bad tracks on the disk, it won’t be to such extent. Actually these problems are basically owing to the mismatched firmware. So we should select the option of inspecting firmware (the first item of the operations on firmware) at first, in order to know which module is the one we need write. In addition, remember not to write G-List、 P-List and speed module! (Suggestion: First of all, backup the modules I referred to above!)
This can reduce the unnecessary trouble to a great extent (self scan will spend half a day!).Sometimes erase command of MHDD work well; however, it won’t work faster obviously!
