There are numerous magnetized elements on the surface of a hard drive. When these elements lose their magnetic properties, data cannot be written or read on them. For example, the gradual wear of the magnetic coating of disks may occur due to the smallest dust particle leaking through the filter.
Bad blocks are corrupted hard disk drives that contain various information: user files or service data. They are also called failed or unreliable sectors. You cannot write or read the information on bad blocks.
One of the leading causes of bad sectors is the interrupted writing of data blocks to sectors due to a power outage. Also, bad blocks may appear on the hard drive due to manufacturing defects or mechanical damage.
Signs of Having Bad Blocks
The more bad blocks on the hard drive, the lower its performance. After some time, the information storage device can completely fail – it will be very difficult to restore it, and in some cases it is impossible.
- Frequent Occurrence of The Blue Screen of Death
- Errors When Copying and Reading Files
- The System Boots Longer Than Usual
- Files Start Disappearing from The Dard Drive
- Some Programs Stopped Running Due to Unable to Read Data
- Constant Lags and Freezes of The Operating System
The most common associated sign for the unreadable block is the destruction of the logical structure. Undisclosed partitions, lack of folders or files – a consequence of the fact that the file system was partially damaged, partially getting into the broken sectors.
In such cases, with the sector image obtained with the help of the software and hardware complex, it is still to work as with a disk with logical failures. That is, specialists make a further recovery with the help of special programs.
Hard Drive Bad Block Data Recovery
Recently we received a failed hard drive. Files stored on our customer’s Seagate hard drive became inaccessible, so he requested a technical evaluation from PITS Global Data Recovery Services. The problem with the hard drive was that it was not recognized on the computer making the data unavailable. The drive was delivered to the lab, where we started evaluating the device. Our engineers assessed the specialized facilities and determined that the problem was in bad sectors of the drive.
To work with “bad” disks, which are considered physically faulty devices, our specialists use the latest hardware and software systems.
With their help, we accessed the disk’s contents, which could not be handled by standard software tools. Special tools allowed our engineers to subtract the contents of the entire disk space that was not damaged by bad sectors and then improve the quality of recovery.
To do this, multiple attempts to read data from bad blocks were made in a special mode, and most of them were successful. We had to access the service area (SA) of the device and restore the modules located on a platter. Our engineers used our developed data recovery tools to achieve the best results.
As a result, in our safe of airborne particles ISO Certified Class 10 Cleanroom, the entire SA of the Seagate hard drive was backed up for further recovery. Corrupted modules were replaced, and all data was successfully recovered. The files have been copied to a brand new hard drive and returned to the happy customer.
