Typical hard disk failures
Hard disk failures can be grouped into three major categories: electronic, mechanical and logical.
Electronic failures are usually related to hard disk controller problems. The most common symptom in these cases is hard disk detection failure by the computer BIOS. In such situations the information stored on the disk is most probably intact and its recovery is 100% possible through replacement of the defective components.
If you encounter problems of this type, the complete rescue of data from you disk will be certain as long as you address our data recovery service.
Modern hard disks are sophisticated and quite delicate devices. Although their manufacturers declare for them a very long lifetime (for some models up to 5 years of warranty, 600 000 hours of error-free operation), problems with their extremely precise mechanics do sometimes arise - malfunctions in the heads, the motors or the head positioning mechanisms.
Most often mechanical failures are caused by concussions, manufacturing defects, static electricity or power surges.
Typical symptoms of mechanical failure are the abnormal noises heard from the device - ticking, screeching, whining, etc.
If unusual noises begin to be heard from your computer, immediately turn it off and call a specialized service shop to diagnose the problem. Urgent measures for rescuing the information must be taken ...
In most cases the repair of a mechanically damaged disk is entirely possible (defective motors, mispositioning or malfunctioning of the heads) and the stored information can be completely recovered.
In all cases of mechanical failure it is necessary to disassemble the disk, which can be done only by qualified professionals at a specialized repair shop.
If you encounter problems of this type, refer to our data recovery service.
Errors related to the logical structure of data stored on the hard disk
In such situations the hardware operation of the disk is normal, but the access to data is disturbed or distorted - that is, information becomes inaccessible NOT as a results of data destruction but because of the destruction of the addressing patterns to these data.
Damages of individual sectors, including MBR, BOOT, FAT, ROOT, MFT, etc., are not fatal for the success of data recovery. Even if the file system of your hard disk, CD, diskette, flash memory stick or ZIP disk is damaged or destroyed, still not everything is lost! It is highly possible that the information can be recovered.
If you encounter problems of this type, we recommend that you stop using the disk immediately and seek help from a specialist. You may refer to our specialized data recovery service.
