There are two main methods of recovering data from failed hard drives.
First of all, you can run specialized data recovery software that could retrieve all of your important data files. In the majority of cases, you will be able to recover the data from your failed hard drives without too much trouble using data recovery freeware, or purchase fully supported software if you prefer.
Please note hat data recovery is not always possible if the actual problem is due to aging or faulty hard drive component such as a broken head arm. In those extra-ordinary cases you would have the hardware fixed by an expert technician before being able to access any of the precious data on the hard drive.
As far as data recovery in concerned, there are no limitations to the physical size of your hard drive. Whether you are trying to recover data from a 1 MB pen drive or a 300 GB Ultra-SCSI drive, you should still be able to recover the data.
Additionally, there are no limitations to the different types of operating systems which you may be trying to recover data from, such as Microsoft Windows to Linux systems. This also extends to include different file formats such as FAT32 and NTFS which are very common file formats for Windows systems, or the Mac OS file system used by Apple Macs.
Information can be retrieved from all sectors of the hard drive – even files that you may have deleted in the past which had ended up in recycle bin prior to your hard drive failing would be recoverable.
Secondly, data recovery experts will be able to recover lost data from most damaged hard drives. It’s not surprising that most common damage is attributable to drop damage and spill damage, especially in the case of laptops.
At the corporate level, most companies use RAID (redundant array of inexpensive disks) configurations to protect their data and to negate the impact of a single hard disk drive failing. There would be no loss of data if one of the disks in a RAID 5 disk-set failed as you would be able to re-construct the data for the failed member from the remaining disks. However, if the entire RAID volume failed, then that would be a cause for concern.
In the case of a RAID volume failing you would have little alternative but to send your hard drives to a data recovery expert to restore the RAID configuration as well as the data. This would also be the case if your disk partition failed and you were unable to access the data held on that particular partition or disk.
The recovery of your important data and files from failed hard drives is possible using data recovery software. If your hard drives are badly damaged, or the RAID volume-set has failed and the data on the hard disks is inaccessible, requesting professional assistance from data recovery experts would be a better option.
