How do the Big Company Retrieve Data From Damage Hard Disk?

Question

I know if your hard disk is logically damage you can easily use a software to retrieve the data inside it and just format it and the hard disk is back to normal (correct me if i am wrong) but how do they (big company) retrieve data from a damage hard disk which physically damage can someone tell me and is it possible to do it on our own if we have the right equiqment

Answer 1

If by "big company" you mean a data recovery specialist company, the answer is, they have "clean rooms" where they can take the hard drive apart and read each platter directly, without talking to even the onboard electronics of the hard drive, but read the magnetic platter itself. Clearly, such operations ain't cheap.

A clean room cost a LOT of money, so does having the right type of equipment to read the magnetic platters directly (think hard drive maker -level equipment).

Answer 2

Normally a 'Big Company' would not try to recover data from a damaged hard drive, servers use a process called an Array, most are hardware driven, there will be a Array controler and a series of hard drives in the array, if a hard drive in the array fails they would replace it with a hard drive of the same size.

If your hard drive is physically damaged and you need the data from the drive there are companys that will do data recovery, it is extreamly expensive, figure 5 -10 bucks a kilobyte (1K) if the drive is in the gigs you are talking 30-100 THOUSAND dollars (seen that it is not pretty!)

If you have a drive that electronics has failed, getting a drive with the same make, model, and part number and swapping out the electronics will recover the data. If it has been dropped and the heads have impacted the plater the area where the impact is will no be recoverable, the media will be destroyed thus the data will be lost.

Answer 3

Most software solutions can scan the surfaces of the disk looking for recoverable sectors on the drive, even partially. If the drive mechanics have failed, then there are numerous companies that will remove the platters from the HDD and place them into very expensive equipment to attempt a recovers.
Special Note: Never, NEVER, talk your hard drive apart unless you have give up on it, never want to get the data off of it, and just want the magnets inside.

Answer 4

If the damaged HDD had warranty cover, they don't do anything with it.

If it has crossed the warranty period, they just outsource it to another company. People come and collect the damaged drive, and try to recover as much data as possible using specialised machine and sofware.

Answer 5

hi. What make of ext. hd. is it? I had a seagate freeagent ext. hd. fail. OH NO. I figured what the heck. So I pulled it aside to get the hd. out. I then pluged it in to an open exterior hd i exploit to hook up countless hds. It worked. It became into in basic terms the interface electronics, which regarded susceptible. you could %. up an ext. hd enclosure for below $50. do this till now massive dollars documents restoration. desire this helps.

Answer 6

They hire a data recovery specialist. In really bad cases they don't try anything further themselves because they don't want to damage the system any further.

Answer 7

they use a machine for that and if your very rich you can try to buy that kind of machine since your going to buy why not make it as a business for data recvery

Answer 8

They have the right tools and experience.
