Data Recovery X Datenrettung
Damaged hard Drive? STOP! Don't make it worse! Trust your hard drive to Data Recovery professionals!
By applying the most advanced technologies and by optimizing the workflow, the company X Datenrettung realizes the data recovery from damaged storage media of all kinds.
This service is especially appreciated by those who already had experience with the data recovery sector. Also for professional data recovery companies.
We keep those for the sucess irrelevant costs as low as possible and - besides the extensive expertise in modern techniques of data recovery - also aim at the best price-performance ratio for the data recovery.
The general price for professional data recovery is already rather high- even if the harddisk is not seriously damaged. This makes a professional data recovery unprofitable or even unaffordable for many customers and often results in an attempt to solve the problems on one's own account or to contact a company with limited possibilities.
In addition to our technical cooperation with specialized firms, manufacturers, experts and scientific institutions at an international level, we conduct our own research to make the data recovery safer, more efficient and cost-saving. In doing so, we apply our own know-how in the field of data recovery for perfecting and simplifying the data rescue process. The application of innovative methods and the optimization of the workflow enable our company X Datenrettung to achieve the highest success rates in the industry while keeping our prices low. We assess the risks and set them in relation to the costs. That's how we decide whether we can offer a particular service cheap but with good chances of success.
We work closely with our customers. We inform our customer about the necessary steps and risks so that he can decide himself about the method of data recovery.
We take all possible precautions to keep the data source intact. Generally, we work with an image copy of the disk. Of course, your data will be treated confidentially (according to § 5 BDSG).
Here are some of the most common data recovery services we provide:
- Hard drive makes clicking sound
- Mechanical hard drive failure
- Hard drive surface damage
- Accidental data or file deletion
- Accidental reformatting of RAID
- Deleted or corrupted log file
- File system corruption
- Laptop Hard Drive recovery
- Inaccessible drive files
- External drive turns on but no files
An opened harddisk looks like this
A hard disk consists of one or several rotary magnetic disks, an impulse, movable heads, a tax electronics with an interface to the connection with the computer.
It is interesting to work out that at a radius of 40 mm of the magnetic disks and at a rotating speed of 7200 revs, the heads race at a speed of 108 km/h and at a distance of approx. 0.2 µ m above the magnet surface. For comparison: a fingerprint has the height of 4 µ m.
Any resemblance to a record player is only formal. The data are not stored on the disk successively like songs on a record. In order to reach bigger capacities and short access times, the data are distributed in a certain algorithm on the magnetic surfaces.
The write/ read head exists of two heads: Writing head and reading head. Due to the rotation of the write/ read unity these both heads are on different tracks. The synchronisation of both heads is guaranteed by the hard disk programme (Microcode). The parametres of this programme are summarised in the production and are individual for every single hard disk.
What you should not do
1. Switch the computer on and off for several times while it is clear that the harddisk does not work. In case of a malfunction of the harddisk, the magnetic disk surface, and thus the stored information may be further corrupted.
2. Put the harddisk in the fridge or roast it. Although a number of forums will encourage to do so. Even if the malfunction is due to overheating of the components, the strong cooling can only, if at all, activate the harddisk for a few seconds. This time is insufficient for a data recovery. There are also cases where the hard drive works again momentarily after some rest (not within the refrigerator). But these cases are extremely rare.
3. Unscrew the hermetic case.
Even if the hard drive no longer starts, it is still far from clear that the engine is broken or locked. Quite often it is the controller that, due to an error, gives no signal to start the engine. Sometimes the heads suck to the magnetic surface outside the parking zone. This results in scratches if the wheels are turned forcibly. Quite irrespective of the fact that thereby dust gets inside the harddisk.
4. Replace the controller, if one is not sure that this is really the problem and that the harddisk type allows to do so.
In doing so, one risks to lose both the data as well as the controller. Due to achieve the large data densitiy of modern hard drives, the controller is set individually for each harddisk and therefore cannot be replaced with an 'identical' PCB. Attempts to do this anyway will only result in clicking of the hard disk. Sometimes even the exchanged controller will be destroyed.
5. Solder elements of the controller, if you are not sure that this is the reason for the malfunction.
6. Run programms such as CHKDISK, SCANDISK, Partition Magic etc. ,
if one is not sure that they can really fix the error. If the hard disk has malfunctions or surface damages (Bad Blocks), the programs can restructure the still existing data in a way that the correlations are not found anymore.
7. The tips from the Internet should be applied with great caution since they have unfortunately not always been written by specialists. The solutions for hardware damages are usually very strong related to the specific model of the harddrive. One should be careful in forums that advice for hardware repair without designating the exact model type.
If the drive is not recognized by the BIOS and makes unusual noises such as tic tac sound, the disk is defective. You should not plug it to another computer, not in an external casing, not try it on Linux, etc.
Failure to comply these precautions can aggravate the data recovery process or even make it impossible.
