If you have ever seen hard drive recovery software advertised, then you probably have questions as to what this software can actually restore. Data recovery software can successfully "save" files that were deleted, hard drives that were formatted or crashed, and other data that was damaged because of a hard drive emergency.
The process of hard drive recovery usually takes 2-5 days, and most companies prefer to work on your system at their own site. While there is portable software that can reportedly save files from data corruption, these techniques are not as advanced as professional data recovery services.
Usually, hard drives fail for two specific reasons. First, there is logical failure, which is the result of damaged system integrity. The bytes stored on your system are incorrect or have been corrupted and thus the system is not recognising files that are saved on your system. In contrast to logical failure is mechanical failure, which refers to a hard drive problem. The hard drive could have damaged parts and may not be functioning correctly. This could be due to old age, a faulty unit or some other damage.
Categorised along with logical failures are human errors, such as accidental deletion, accidental formatting, and software errors. Besides data corruption, one must also consider information loss due to lost partitions and bad sectors. The good news is that your file(s) could very well be saved; in fact, your whole system could potentially be restored. However, doing so will be no easy feat. A word of caution: do not continue saving and deleting files, as this could ruin your chances of a hard drive recovery.
Why so? Because though you do not see the file, the lost data may still be located somewhere on the hard drive. What you see on the screen is not the true directory of contents, but the accessible directory as reported by the system. Therefore, it is very possible that the data you seek (and that you are fretting losing) is still somewhere on the hard disk�it merely needs to be accessed.
The data section on the hard drive has been allocated for reuse, once something is "erased." However, that section of data may very well still exist and this could be recovered using hard drive recovery. Do not give up hope. You do not have to rebuild if there is an option to recover!
