Mechanical failures of any type could cause the storage media to get physical damage. CD-ROM’s and floppy disks are sensitive to damage. Magnetic fields could ruin floppy disks and the metallic substrate on a CD-ROM could become scratched causing damage to the media.
In a hard drive, as complicated as it is, there are many parts that move and run at high speeds upwards to rpm’s of 7200. No matter how the damage has occurred, physical damage will always create some loss of data. Sometimes damage could happen to the file system’s logical structure, which requires rebuilding before the technician can gain access to the data.
However, since most of the population have no knowledge in repairing hard drives and the physical damage that can occur, we have to turn to specialty companies. These companies have specialists in data recovery due to destroyed or damaged storage and hard drive devices.
Because manufacturers seal hard drives before shipping, any settled dust on the surface of the disk will cause even more damage to occur. This means that to repair the drive the facility must have a clean room. If the data recovery company is reputable they will have a Class 100 clean room on site. Further, they will have all the necessary experience and tools to recover accurately and reliably the lost data.
But there you could better news than expected after the recovery. While the process may not recover 100 percent of the data all the time, it consistently returns most of it, minus a few damaged records. That is, even if your hard drive went through a fire at your home or office, and may have survived water damage.
Using a data recovery service will help you retrieve your lost lost data.
