Burned drives data recovery

[waqas_ali766]

Hi
Got 3 servers with 18 drives , fully burned. Need all the data

Top plates of every hard disk have a smoke signs.
Only one data has been repaired and cloned successfully.

any one clean such kind of Hard disk before ?

A heavy fire. The disk plates might get de-magnetized under a high temperature. And if this is the case, the data is completely lost.

Shuttle Columbia's hard drive data recovered from crash site:

Edwards said the circuit board on the bottom of the drive was "burned almost beyond recognition" and that all of its components had fallen off. Every piece of plastic on the model ST9385AG hard drive melted, he noted, and all the electronic chips inside had burned and come loose.

Edwards said the Seagate hard drive -- which was about eight years old in 2003 -- featured much greater fault tolerance and durability than current hard drives of similar capacity.

Two other hard drives aboard the Columbia were so severely damaged that it was impossible to extract any usable data, he added.

Before recovery could begin, a great deal of dirt and other debris had to be cleaned from the storage device. A rubber seal at the top of the hard drive was completely burned off enabling dirt and charred elements to enter the casing. Everything but the drive's platters were virtually unusable, remarked Edwards

"The heads were bent and they were touching where they shouldn't have, so we had to carefully cut and bend metal away from the platters to get them out without causing more damage," said Edwards.

Once cleaned, the platters were placed into a spare drive and carefully aligned with a new motor. Because the original circuit board was destroyed, Kroll had to use trial and error to determine which firmware was needed for the device.

Although damage to the drive worsened once the team got it up and running, the data recovery specialists retrieved 99% of the drive's DOS-formatted contents. "It was only a couple hundred megabytes of data, which isn't much by today's terms, but the data [the drive] contained was very valuable," noted Edwards.

Hi
I not think so that the platers goes demagnetized. Because i washed 1 drive top plate.
All are clicking. After alot of strugle i can read full fw and rom of all 5 drives.

All drives have 2 head working out of 4. The top plate head is not working.

I opened one drive. And i see that the top plate have smoke sign.

I cleaned the sign with isopropyl 100% pure. Then dry with cotton swab.

Then the drive detect one time with new heads. And after that again start clicking.

Problem is i cannot pull out all platers together for cleaning. Because wd company put a big black spacer between the platers.

Only way is to pull out platers one by one.which i think is extremly dengerous.

Still thinking what to do, to get better result.

am not sure it will help or not but just an idea,

by picture all drive seems to contain same FW version and you have already cloned 1 drive, means you have SA backup for that.

I would prepare a donor drive with already backed up SA and try hot (sure after cleaning platters) see if that helps !

Hi Mind Merge

Hot swap is not easy in these drives, already tried and no result.
Most of the drive are fully latest which is not fully supported by tools. HEAD map in ram also not support by PC-3K , SEDIV, MRT.

Many many thing are not supported.
I have SA Backup of 4 drives out of 5. and backup SA is very difficult.

These drive works fine when i block read channel, and gives me access to SA. other wise start clicking after calibration due to plate 3 bad.

WE are trying to add some function in sediv to make head map in ram. and then cloned the remaining good platters which are 0 1 2. then try to clean 3rd number.
With Head 0123 hdd clicking, and for run the drive with head map 012 we need head map in ram, its the only way.

very very hard case of my life. gives a head ache.
well trying, will update if i get any success.

If you're going to to that, then I suggest you physically remove or lift up H3 to prevent further media damage.

[waqas_ali766]

Hi
No need to lift up the H3, because i already Cleaned the Plate 3.
See the parking ramp H3 is melt due to head, but others are good.

I have ordered some chemicals and special high quality class 10,000 clean cloths. for these drives. when reached will test on my own drive first.

here are some pictures

we have pc3k express edition if it may help.

[waqas_ali766]

Hi Mind Merge
I have all tools.
PC 3000 express
MRT ULTRA
Salvation DATA Compos
SEDIV = Worlds Best for any WD drive, no one can beat.

Problem is its a fault of Platter, it takes time to clean them.

I am trying to get good chemical to clean, right now i test ISO-Propyl 99.9% , Ethyl alcohol.
Ethyl alcohol gives good result in cleaning, as compared to ISO-Propyl 99.9%.

Once the Drive become physically OK , then a PC 3000 or MRT work will be started for diagnose.

ok, good luck
