Janos ,
I Have a Stupid Question what Imaging Software/Hardware You Are trying



Amarbir,

I am using own solution. ;)
I always image under Linux, with my patched kernel (retry removed), and one own wrote script, wich uses dd_rescue in the core.

It can do all the needed steps, like jumping sectors, read forward, backward, continue, force the bb area, the only one thing, wich it does not supports, the ECC ignore reading.

But generally, it is not needed.
Anyway, i have other solution in these cases, if it is needed.

(the case, in the first post is already recovered, but for interesting testing, i still have the drive, so the original question is still actual. :) )

Thanks,
Janos

I have already pointed out what seems to be ignored : commercial available tools , on which the majority of repair shops and DR rely on, are only tools to access the SA or firmware zone, driven by human beings. We have to use our logic skill / capabilities, unless it is a simple, "clickable" solution.
What's worst, the more I go further researching and experimenting, the more I can do without those expensive tools. The DR is moving to phisycal, hands-on-drive level, and if you really want to do magic, if you know sufficiently how things work, you can write down your own tools even in Turbo Pascal (maybe forgetting GUI but who cares ?). Enough said.

I have read back the first 20 posts now. :(

Doomer, Amarbir

This is a technical forum, so please see the posts like this way, and if somebody have any problem with each other, please discuse the problems in PM, please! :)

Doomer, thank you for the answer, i will try it if i have a little time for learning.

Can you say for me, exactly wich step in error handling is wrong?
If i trying to disable the steps, wich is what i need to disable?

Btw, the error correcting attempts, is important in DR, so skip this step causes lower imaging quality....

Thanks,
Janos

custom made tools best to perform. but commercial tools give us more ease, time consuming solution to perform.

I doubt it is possible with dd
the idea was in sending software reset as soon as possible when drive found a bad block (stays in busy too long)
But as far as I know dd cannot send software reset

Yes, i know, what you talking about.
No, dd don't send any sw reset, the kernel does it, when the drive don't respond in the timeout period.

Maybe i can set up the drive for using individual error handling solutions, like ECC retries, seek off-and back count, trying to read off-track, and similar.
This is why i am asking, wich attempt causes the fw bug, if you know the answer....

The interesting part, on exactly the same block, in the beginning, the drive can read the content during the error-handling code runs, and i can mount up the partition.
But after it crashed once, the drive almost immediately hung again, if i trying to mount again.
(of course, i am working on readahead = 0, and readonly the whole drive...)

Thanks,
Janos

Hello Gurus,

Let me start the questions: :mrgreen:

I have one ST3300931A, with a lot of bad sectors (not exactly in fixed place), and when i trying to image, i have got this message on the terminal:

This point the drive is knocks one big, and stay BSY forever.

Now, the drive can init again, but very soon drops this issue again, so, in this way, i can't countinue the imaging without hw controll....

Somebody have any suggestion?

Thanks,
Janos

Excuse be, but you was, who asked the solution about imaging. :lol:
In this way comes out the custom made solutions.....

Amarbir, you know me outside this forum and 'you know'. Me and other people who have developed custom solutions are not going to post any 'proof' maybe because we don't want to self-jeopardise our market - that, if not far west, it is close to. Commercial solutions are commercial, custom are more like capital assets. And NO, info won't leak - just to make someone disappointed. I am somewhat different from other people, and I know it, but common sense is common.

Hello gurus,

Now I am trying to selfscan one 7200.7 (PUMA) drive.
The selfscan started good, but after some hours, I can see the drive gets in endless loop in test 40.

At this point, I have switched off the power and on again.
The drive shows this:

I have changed the AGE from 40 to 41.
The test continues, but i am not sure on the right way.
Now the drive is on this state after more than 24 hour:

Somebody can help me how to step back to the normal way of ss?

Thanks!

Hi
Try to press "." several times to see if it's doing something or not....As far as I know this is a long test but 24 hour(for 2 heads) is too long...something is wrong there...
And are you sure that after test 40 comes test 41?...look in log 4e to see the test sequence...
