Data Recovery – Some Basic Information
Ever had the feeling that you’ve lost something and feel you’ll never see it again? Data Recovery tries to bring back the loss. We figured it’s time to answer the common questions we receive! When unexpected data loss has happened; this is when data recovery becomes very useful. Overwritten partitions; Windows re-installations; blue screen of death (system boot failures) are just a few examples of where data recovery becomes useful.
What is Data Recovery?
It’s the process of retrieving lost, deleted, corrupted or even formatted data. Most hard disk drives, USB drives, SD cards and even common smart devices (phones and tablets) are best for data recovery processes. These one common thread between all these different types of storage media; which is they all use electrical components which are prone to failure.
Hardware can be physically damaged (such as being dropped or mistreated); fail due to being faulty or old. Sometimes it just stops working with no warning or reason at all!
The recovery process will source out the data that’s stored on the hardware; including situations where it’s not accessible through normal methods.
Types of Failures
There are two different types of failure which data recovery processes are able to deal with.
Logical Failures: This type of failure occurs at the file system level. Logical failure is also known as software failure. Easily identifiable as the storage media can’t be accessed or throws errors when being accessed in standard ways. Companies that offer data restoration services will use specialised software to retrieve the data.
Such software is usually on the expensive side; and requires specialists to run properly. Using data recovery software without the correct knowledge and training may result in causing further damage to the data – making it nearly impossible to gain any further access.
Physical Failures: As it describes; a physical failure occurs when one of the internal, physical components is at fault. This could be the reader heads within a tape drive; or even the motor that drives the hard disk.
When internal components are at fault, the only way to recover the data from the hard drive is to replace them with identical components in a dust-free environment known as a “clean room”.
An expensive experience for anyone who has had to go through it.
Limitations of data recovery
Not everything goes according to plan. Not all recovery attempts work. Depending on how the data became unavailable; can impact the end result. A few examples of where data recovery may be unsuccessful include:
- Severely damaged storage media
- Data location has been missing or cannot be located by recovery program
- Deleted or lost files are too old to recover
- Heavily infected files and folders which make header information inaccessible
As a result; the best chance to recover your data is by removing the drive immediately from use.
Don’t want to go through the stress and cost of data recovery?
It’s a fairly extreme case needing to use data recovery services and software to reverse the effects of data loss. The best technique is to perform regular backups of your important data. Test My Backups uses this preventative measure; instead of waiting for disaster to strike your data.
