Is it possible to block head Over ROM MQUBD100
September 4th, 2019, 9:15
Is it possible to block head over ROM before heads reading data over platter
Toshiba MQUBD100
I have a very bad case.
4 head 2 platter.
Platters upper surfaces totaly starched.
Surfaces
0 good
1 bad
2 good
3 bad
Heads also gone very bad . Bended abnormal. Clients DIY disaster.
I swapped head. 1st try I guess MRT recognised disk after long wait. I could checked only g list was empty.. Plist couldn't open. Tried Head map on MRT DE. Not possible. And after short time drive again clicking. 2nd power on Clicking long time. My guess trying to add huge defect and drive clicking. Or heads gone again.
My question
Is it possible to block head 1 and 3 over rom. I imagine that to block that heads before heads reading /writing data on platters. Maybe a lil chance if it's possible
I killed 1st donor. Would kill 1 or 2 donors for that case.

You don't have any idea how the Toshiba drives work, do you? 
To start the media firmware the drive has to read DD.bin and some other modules from surface 3.
Otherwise it runs the Flash firmware and the access to platters is blocked...
Some terminal commands could help in your case , but I doubt they are implemented in MRT or PC3K...

Yes I dont know much about DR and Toshiba drives. But;
I removed PCB from drive. And MRT recognised drive info and reading ROM and ROM modules. Showing head numbers . And Zone tables. Meaning, head map in ROM
MQABD Series like this. MK series not like this.

Can you upload your ROM and CP dumps?
Customer mixed PCB's. I have 2 PCB attached both.
İf possible, I need H0 and H2 active only
thanks.
I count from bottom to top.H0 bottom, H3 top. I am not sure whether is true

I am sorry to say, you totally beginner. Next time don’t play with customer’s drives without proper knowledge. Wanna learn , use donors drives, scratch top surfaces by own , try to run it and read data from the rest surfaces . Make the sentence 5-100 time before put in a danger your clients. —— It is like surgery doctor, during operation with human heart trying to read google to know what to do next. BTW , Toshiba heads, starts counts from TOP .

AISI, the head map is here (CP 0xEF):
ISTM that, if you want to avoid heads 0 and 2, then change the map to ...
However, ISTM that you should avoid the damaged surfaces by cutting the damaged heads from the headstack, but you'll have to ask others if that approach makes any sense. Maybe you just need to bend the top head out of the way (and cut the third head).
Note that the CP in ROM should have an XOR8 checksum of 0x00 whereas the same CP in your resource dump should have an XOR8 sum of 0x81.
BTW, I think it would be a good idea to experiment with your donor first.

Yes. Are you kidding?
Yes because I cannot access drive in that condition .
Yes I am trying to find to access data on platter.
Yes because I removed PCB from drive.

Thank you. User opened own drive before. And after me it will go garbage everybody knows.

Are you sure?

I couldn't find this data in Rom.bin
However, ISTM that you should avoid the damaged surfaces by cutting the damaged heads from the headstack, but you'll have to ask others if that approach makes any sense. Maybe you just need to bend the top head out of the way (and cut the third head).
Note that the CP in ROM should have an XOR8 checksum of 0x00 whereas the same CP in your resource dump should have an XOR8 sum of 0x81.
BTW, I think it would be a good idea to experiment with your donor first.
I cannot cut head physically . Don't have any experience and I afraid to do.
I have changed upper platter with donor. Tried with both PCB. Nothing changed.
I am bored . Still I don't know which is H0 . Upper or bottom? I feel like walking blind in desert. Lol. Kind a game over time. Maybe I would try with another drives for experience in future.

H0 is the top head . But h1 will be enough to read nessesary things from SA .

Hi ,
You Need Original Platter And then Try Read From H1 if H0 is BAD , This is crazy you change platters ,did you see that stupid video that is posted on facebook group of platter cleaning with cotton bud and replacing top platters lol ,Dr Kiev is right H0 is top head in This drive

I have a case that died before came to me . It's kind a crazy stuff customer know everything ended before came to me. Not decided from YouTube video. I had cleaned platter before have worked . But not tried this drives platter. I need more experience to do .
It's dead case before came to me I know.
I would spend 1 more donor. But I am sure there is % 1 chance. Consantrating...
Life sometimes playing games with us. Lol
