False beliefs about data recovery

Losing data from your hard drive is not, fortunately, something that happens every day. For this reason, the majority of clients that request Ondata’s services do not know about the problem of data and it can be fixed by any data recovery service, and sometimes their expectations are very different from reality.

Some false beliefs about the operation of hard drives are not very helpful in the mission to rescue lost information. In this series of articles, we try to clarify some doubts that we find each day in the data recovery service.

“It’s not a mechanical failure because the disc did not fall to the ground.”

The discs that have suffered a fall usually have mechanical failures, but that does not imply that all mechanical failures are caused by falls. Sometimes, the discs come badly from the factory and some internal part begins to fail until it ends up causing a mechanical failure that leaves the disc unusable. There are discs that with only one or two weeks of use fail mechanically. There may also be other situations, such as voltage spikes, which end up causing mechanical failures.

«Nothing happens to the disc, it just does not work».

We understand what users want to say when they present their damaged disk: the disk did not suffer any voltage drop or rise, it was not formatted, etc. But when a disc does not work, it’s because something happens to it …!
Although they are not as striking as a disk that makes clicking or knocking noise, or that smells of burning, those other failures in which the disk “does not happen at all” will also require specialized tools and many hours of work on the part of from the data recovery lab experts, sometimes even more than with other types of failures.

“But if it’s a very small pen drive, it has to be easier to recover. And cheaper. “

Pen drives or USB drives work with flash memory, which is a more modern technology than the magnetic plates of hard drives and requires different tools and processes. In many cases, it is a more complicated process than that of hard drives. The ease or difficulty will depend on the technology that has to be used for the recovery, rather than the size.

Step 2

“Pieces? I do not need them to fix the disk, I just want the data. “

Although Ondata International has a large stock of spare parts, it is becoming more frequent, due to the number of new models that come onto the market, that we have to acquire specific parts for some recovery, most of the time abroad. In fact, the spare parts not only have to be from a hard drive of the same model but must have the same part number ( part number ) so that they are identical.

These parts are necessary to put the disk into operation in a controlled situation that requires the use of specialized machinery and software. That is, the pieces are to get access to the data, not to repair the disk. Once the data is recovered, it will be dumped on a new disk.

“For that cost, I buy a new hard drive.”

Without a doubt, buying a new disc is an economical, fast and simple solution … but the problem is that the new disc will not contain the lost data.

Data recovery services have high costs because they do not consist of replacing one disk with another: to maintain a laboratory it is necessary to acquire machinery and software licenses that have a high cost, and all this has to be updated continuously (every day they appear new devices, operating systems, failures and viruses that did not exist before, etc.).

In addition, technicians and engineers have to be trained constantly and the courses they have to receive, many of them abroad, also have a cost.

“That’s just changing one plate for another and that’s it”.

As in the previous section, replacing a plate with a new one or putting the old plate on a new disc will not solve the problem. And of course, there can be many other breakdowns that do not consist of a failure of the dishes.
