HDD GURU FORUMS

hi guru
i have a WD5000AZDX-00SC2B0 harddisk with burned pcb,i changed the pcb and trying rebuild rom from sa but mrt can't rebuild mod47,i have access to mod40 ,is there any way to rebuild mod47 from module40 by hex editor?

PCB number? 701640-003? Tahoe?
If yes, then rebuilding ROM from SA via MRT should be OK.
What about native ROM?

pcb number 2060-771824-005 trails family.
the pcb rom,mcu,buffer burned and the harddisk head was clicking i change it with WD5000AZRX-00A8LB0 same family and it works but i have problem with module47.

can anyone help extract 47 from this 2 module?

Can you upload modules 47h and 40h from your donor? I believe I have worked out the structure of module 40h, but I need a working example of 47h for comparison purposes.

hi fzabkar
this is from donor to compare

I have the same modules backup...

My preliminary investigation suggests that module 40h consists of several sections, most of which are subdivided into additional subsections, with 1 subsection per head.

This is the module header:

Code:

Offset(h) 00   02   04   06   08   0A   0C   0E

00000000  524F 594C 0100 3000 4000 BF01 D9FC F252  ROYL..0.@.¨.U•R
00000010  3030 3031 3030 3030 0707 0700 0000 5800  00010000......X.
                             offset to table ^^^^

00000020  0000 0000 0000 0000 0000 0000 0000 0000

It points to a table which defines the location and size of each section.

Code:

This is the layout of one of the sections. There are 8 blocks of data for heads 0 - 7.

I think I've worked it out, but it will take me a little time to write it up.

wow it's good to know how to rebuild important module in some cases mrt can't rebuild 47 and do that by hex editor i search the module 47 and only found the header in 40.

Or "maybe" you guys can implement a "function" on MRT to rebuild ROM module 47 from SA module 40 ?

Hi, in WD utility, we have the function named "Rebuild ROM from SA", and in this function, we can generate ROM and ROM modules, and we can generate module 47 from module 40 and module 103.

yes there is a function to do this but not working in this family when i rebuild rom from sa and check the rom module there is a problem in mod 47 and i tested on healty drive sam family to rebuild rom but same result by the way i will call your technical support and i hope help me solving the problem thank you for your attention.

This is the best I can do (see attachment).

That said, if both (?) the PCB and headstack were swapped, then wouldn't it be preferable to import the donor's channel, preamp and microjog adaptives into the patient's ROM?

thanks fzabkar your generated 47 module it works,after writing 47 and repair damage modules the hard disk go's ready and i can access the data you are the best fzabkar
thank you very much.

yes dear spildit i tested before that mrt rebuild all modules only the 47 end with error i want to contact mrt support but the case closed by fzabkar great help,really he is good in hex.

Dear spildit mrt use two method the first trying load from sa backup and if fail go to method two is rebuilding the 47 from mod40 like the attached picture.

IMAGINE!??? If there was like.... a thing... with.... SQUIGGLES on it... almost like... LANGUAGE! Imagine if there was a book, not written in changlish -- that introduced the way the thing worked sufficiently to where people didn't consistently point out how difficult it is to learn given that absolute non-existence of documentation; video tutorials. Or even a tendency for tech support to reply within 3 days.

....Though I doubt they haven't in 30, I just gave up bothering to get a reply.
