quantum fireball AEXA OD50 EX series
I know that the disk is old, but i hope someone with more knowledge will help me or share a light on some ideas on what to do
So what happened the disk was working and than the partition went missing so far i tried w/o luck lot's of recovery programs even managed to create an image from the drive(but cause the data is from unpartitioned disk-corrupted disk i am unable to find a single file).
so my question is

Can i use parts from SE series quantum fireball 6.4
actuator pcb etc...

Just to note disk is not found in
HDAT2, Spinrite
But it shows in bios and when logged in windows or any linux

This is my first post , i have knowledge but i still learn :)

First don't even think about using parts and opening the drive up.

If you can still see the drive in windows and linux with full capacity and if you did manage to image it it's better for now not starting messing it up more.

Start by checking the image file or clone with hex editor. Can you see any "data" at all or you can see only random garbage or zeros ?

Did you check if the drive can be addressed by LBA or does it support C/H/S only ?

Did you ear any strange noise from the drive like clicking ? Can you clone the drive with something like hddsuperclone ?

Can you see the drive with MHDD ? And on BIOS does the drive ID with correct capacity ?

If you can detect the drive with MHDD you might want to try to scan it just some LBAs to see if you do have access to them ...

Are you willing to pay some money for data recovery ?

If the data is of importance to you you better start looking for a reputable data recovery firm as the more you mess with the drive the more are the chances that you do make the data un-recoverable !!!

Do not open the drive up without a laminar flow workbench and even less without even knowing what is going on with the drive !!!

Do you have some firmware tool to work with Quantum ? Did you bother to check terminal output of the drive using TTL ?

Are you willing to pay at least something to get the data recovered ?

There is a HUGE Quantum research here so if you read it all to the end you will get a very good idea on how those drives do work at firmware level ...

http://www.hddoracle.com/viewtopic.php?f=59&t=1192

But then again at this point we don't even know if the problem is not simply "logic" and if you can't simply clone/image the drive and extract the data with something like R-Studio ...

First don't even think about using parts and opening the drive up.
-Never used parts but was considering it - drive was opened after scaning with testdisk(used to work before).

If you can still see the drive in windows and linux with full capacity and if you did manage to image it it's better for now not starting messing it up more.
-Drive is seen in windows and linux with full capacity tho partition is missing

Start by checking the image file or clone with hex editor. Can you see any "data" at all or you can see only random garbage or zeros ?
-Image file has a random garpage of zeros.

Did you check if the drive can be addressed by LBA or does it support C/H/S only ?
-I need to research how to do this.

Did you ear any strange noise from the drive like clicking ? Can you clone the drive with something like hddsuperclone ?
-I can try cloning, yes there was old click of death sound

Can you see the drive with MHDD ? And on BIOS does the drive ID with correct capacity ?
-No MHDD HDAT2 SPINRITE do not see the drive at all.

If you can detect the drive with MHDD you might want to try to scan it just some LBAs to see if you do have access to them ...
-I will do another try with MHDD, i thing there's only DOS version am i right ?

Are you willing to pay some money for data recovery ?
-Timeframe is small so shipping it and waiting is not an option, i also don't know if this can be fixed remotely(almost sure it won't work)

If the data is of importance to you you better start looking for a reputable data recovery firm as the more you mess with the drive the more are the chances that you do make the data un-recoverable !!!
-Data is important but as i said it will take week or two to write everything again cause there's backup from past month

Do not open the drive up without a laminar flow workbench and even less without even knowing what is going on with the drive !!!
-It was click of death https://www.youtube.com/watch?v=UmTFVuEXzwk that is not my video :P

Do you have some firmware tool to work with Quantum ? Did you bother to check terminal output of the drive using TTL ?
-I could test everything and do as suggested if i am told what to do.

Are you willing to pay at least something to get the data recovered ?
-If there's remote option but i don't think it will work sorry for not being so optimistic about remote :)


and sorry for my english

Well on that case if you do want to see the data ever again the only option now isto send the drive to a reputable data recovery firm and expect to pay a huge amount of $$$ ...

Sorry i can't help any further and this is no longer Do-It-Yourself ...

:cry:

I think you have about 3 options:

1) Take the drive to a reputable data recovery specialist. But it seems you are reluctant to do this.

2) Try to image the drive with HDDSuperClone, and then try to recover files from the image. If that fails, then see option #1.

3) If you dont't want to do option #1, and option #2 doesn't work, then accept that the data is gone.

EDIT
I missed this first part:

Considering you opened the drive, SEE OPTION #1! Or accept option #3.

Look here :

and :

Quote:

-Image file has a random garpage of zeros.


Looks to me that the OP did try already to create a image file/clone of the drive while the drive was clicking and the output was random garbage or zeros so ....

Pretty sure that :

- Heads are gone.
- Drive was opened on clean air just because testdisk didn't work.
- Most likely platters are gone.
- Most likely OP doesn't have a clue about head compatibility and other issues related to head swap on those Quantum (aparently very hard to do).
- Aparently the drive does display real capacity on windows and can be imaged even if heads are clicking and aren't reading a thing ...


So this is a HUGE mess ...

So either use a reputable data recovery firm (and at this point it will be VERY EXPENSIVE) OR ... forget about the data ....

And about remote support .... Sorry .... This one does require clean room work ... It's not a software thing or even firmware thing that one can "solve" by teamviewer ... How are one supposed to swap the head stack by remote ? :roll:

I wanted to tell that few years back same thing happened i used test disk and it found the partition and recovered the drive. I did backup and told my friend to do backup every week or so or order a new drive. Apparently he did not listen!

Data is somewhat important either type the whole thing for 2 3 weeks or fix it in next 4 5 days.
The disk was running everyday since 1998. ;)
If it where some ultra mega hellish important data in there i would have stopped on first click of death, that i heard at his office.
I recovered almost all of his data from backups.
I do admit i don't understand the Head swap for quantum drives , and i also did not try or perform one i was just considering it cause it was like this try everything if nothing works than we type.

About remote support i thought just to check for scientific purposes.
