and....H1 died again (after playing with MRJog for H0..did a reset and on spinup heard some loud clicks and when testing... H1..was dead).

. I think it's a random hardware problem.

..and no hardware tools to help discover the problem.

however, I don't have any scope at this time. so quit telling me to send my hdd to a pro :lol:

I'm chasing for a new donor..and meanwhile..I learn things and develop further my application.

I'm sure that someone, sometime will find useful info on this topic.

Did you manage to "revive" the head ?

nop. but for few hours I had that head working. tried to perform all the actions I did before it worked..with no success.

there isn't also a cold/hot problem. told ya that I had few times when the read channel was entirely dead (for all heads). the hdd was badly damaged when it fell down. perhaps it's a alignment problem with the hsa, platters etc.

I think I''ll try the kill head1 again. I need 2 SA valid heads to test my app, on.

Good point!

@Louis

You shouldn't mess with both heads adaptives at the same time.

BTW, I like your work.

here's a picture with mod 47 (ROM adaptives for a 4 headed drive) pre ROYL.

you can play with those MR Jog values to see when the head can't read. those values are also present in SA mod 41..so you'd better try the operation in safe mode.

from what you see..all balance around +- 0x600 value.

it will be nice to find..how those values are generated. since it's head-dependent..there must be a factory module to "tune" and gen those values.

I have depoped the H1..and re-dimension the max LBA..so from 200Gb now shows 150. I can work with it and test my app on a good SA.

the second drive it's a pre- "marvel" model. I believe the firmware prior to 2004 wasn't so standardized. this model doesn't have a mod 0A from where to get the head map..like newer version so called marvel..or later..royl. in this case I get the head map from ATA ID. however..in this case I can't read the H4 although it presents as having 4 heads.

the head is there..only that it's not readable in SA. I tested the readability for positive tracks and it reads fine. perhaps the head's zone 0 wasn't formatted. :roll:

I'm aware of performing write/sector to test the head..could lead to data destruction since I don't know what's there. until I learn more..(where it' safe to test head write) I'm keeping myself at a distance from writing SA

the LBA size I set it manually. 3/4 * original; checked that "clear translator" when depop. then I did a full format with p list. then a SS. however I don't know what happened because the P/G lists are empty now. I tried a logical scan.and stopped at 1% because it was horrible long. I have now 2 good heads on SA where I'm interested. for the moment I'm not interested in the rest of the disk area. I'm happy that it's stable and no more clicks and other ugly sounds.

for the so called "marvel" drives...(like mine) there isn't a module holding the rom image...as for the royl. for the royl models I think it will be easy..let's say if you find a closer PCB and you can access the SA with it..then read the rom backup modules..and compose original rom image.

How did you set it manualy ? Using 3.0 or editing ROM with hex editor ?
SS can take days ..... also you have to stop it using ss stop at the end ...

3.0

although I don't know at this moment what those LBA1-LBA3 means..I set all 3 at 3/4 of original size..after cutting one head.

got my hands on a ROYL drive. (donor+patient)

few year ago it was taken to a DR and back due to missing donor. the DR spec. told that it requires a donor. the owner got it back and didn't done anything with it till today...although meanwhile he found a donor. initial, the patient wasn't even spinning. the owner was surprised when we plug it on and the drive came ready in K.M. I can access the SA, read all mods..and all are "green" when checking with VSC firmware function. he said..well look that in fact the DR did something to it.

what I noticed is that with this ROYL, I can't perform basic vsc commands like spin up/down...in kernel mode. it complains about perm ovl not loaded, thing which didn't happened on "marvel" models, where I was able to spin down the drive before unplug it.

I tried to load its mod 11...and it throws "not compatible" error. also with donor's mod 11.

so the DR specialist flashed somehow other rom firmware which isn't compatible with the SA modules.

I have to regen the rom firmware, I mean. to code my app to do this.

had a look at mods 102-109 and are all there, just fine. I have to figure how to stick them together. Maybe I should extract the rom backup mod (0x010x)..flash it..and then flash the other rom mods...after changing internal names. this way I hope it will handle internally the mod location/positioning at the eof rom.

teh big problem is that the hdd it's with "masked" rom. so if I screw it up..I cannot use external programmer

I've put the donor's PCB to the patient and windows found it. however...it doesn't work to well...it blocks and hangs during file transfer. I believe that the donor's rom version it's closer to patient's one...so it loaded the sa mods. in the end..I have to regen the rom to solve the problem

the rom it's type manteca, tricky one...it resets itself at the end of the flash..which is bad because we can't verify.

jtag or 2 resistors + U12

the goal it's to write/regen the rom with my tool.

I know what modules to use. beside..I don't know what to use in wdr to regen the rom. and since it's undocumented and no more supported I risk doing bad things.

I'm working right now at my app. The gui it's only an aspect of the whole project. I'm building along a low level library with wd vsc...so my app will use that lib..which handles all low level command - wd internals.

today I've finished gathering all the code into my GUI app, required to do a ROM regen for the royl drive..and give it a try. it worked. now I have the drive with its original rom.

I have recovered directly from windows one of 3 partitions (about 150gb). on other 2 it seems that there are some problems with bad sectors?

the SMART was error-less...but in this situation I believe it will go fast to full. It's a bad thing to do a scandisk? I did this on one partition but it works veeery slow...at 230.000 files..about 1 file record/sec.

the drive was opened by the f DR spec...which flashed an incompatible rom version...probably never heard about rom regen :lol:

did a wd diagnostic tool on it and the SMART error went red. now the drive is BAD. the relocated sector count gets incremented while under windows.

at this moment I'm asking if I could have a bad head...or a head with wrong adaptives? or just surface bads due to the mr DR spec..when opening the drive? notice the bad pattern..on this 4 Head drive.

I know that the LBA it's a linear function, it will be interesting how it varies along the platters. it will be something like from [0-x] head 0...[x-y]..H1 on entire platter surface...or it jumps from head to head inside each Zone? I'm trying to find if those bads are from a specific head...but the MHDD shows LBAs.

I've read an entire partition (150gb) without a single error. the errors are on the other 2.

Hi louis, I'm reading you thread from the beginning, but didn't had nothing interesting to say (but had many interesting things to read

)!

Regarding your new task with WD6400AAKS, why don't you try making a raw copy from that disk to another good using ddrescue? So you could copy as much data as you can in a safe place, and than you could try to see inside with other tools like R-studio o Ontrack Easy Recovery, without having I/O errors!!

I'm afraid that going on with tests on a faulty disk you could damage head if the patter surface is damaged!

I Think that ddrescue (not dd_rescue that is another app) is the better option because first copy all good blocks, and than try to read errors by splitting block size. ddrescue it's a GNU Linux app, but you should also find some cygwin port for win32.

Best Regards
Paolo
