Hard drive data recovery services

• Hard Disk Drive:

Hard Disk Drive are an enclosed disk drive that contains one or more metallic disks for data storage. These drives are non-volatile in nature and have ability to store encoded data on a rotating magnetic platter. Even though, these platters made up of glass or aluminum alloy but we can find a thin layer of magnetic material used on the surface of these platters which helps in the data storing process.

Hard Disk Drive (HDD) introduced in 1956 by IBM as a data storage device with a simple motive to maintain their accounting but later the need of huge and reliable storage device led this simple Hard Disk to a complex and more advanced form like: RAIDs, NASs or SANs etc. The undeniable need of huge storage devices among business organizations and individuals not only compelled the IT industry to produce storage devices with great flexibility and enormous storage capacity but they also had to find a better clarification in case of sudden and unpleasing drive malfunction or data loss. Hence, Data Recovery Companies like: eProvided emerged to be the solution when data loss strikes.

Characteristics of Hard Disk Drives:

• Hard Disk Drives (HDD) contain moveable parts like: rotating magnetic platters and moving heads which make HDD weak or sensitive towards any physical hurdles.

• Platters used in Hard Disk Drives (HDD) coated with magnetic materials. Hence, they should not exposed to high magnetic fields.

• Hard Disk Drives (HDD) need more energy to run as compared to SSD’s.

• In Hard Disk Drives (HDD) the computer searches around the rotating disk for particular data which can be time consuming.

• Hard Disk Drives (HDD) are cheap and affordable.

• The mortality rate, speed and reliability is low on Hard Disk Drives (HDD)

• Data Recovery is (in most cases) simple and easy.

• Solid State Drive:

The Drive being non-magnetic and non-optical but a solid state semi-conductor promises faster access with better physical flexibility towards extreme temperature, shock and unnecessary physical vibrations.

A Solid State Drives are a high performance plug-and-play storage device that have no moving parts and contain DRAM or Flash Memory Boards which designed to resist the unnecessary physical vibrations and shock so to provide trouble free performance even in an uneven environment.

These SSD designed with a CPU to manage data and are faster than other conventional rotating hard disks. Thus, they recommended for server systems where time is crucial.

Characteristics of Solid State Drives:

• Solid State Drives (SSD) have no moving parts, consists of flash memory chips (NAND Wafers) so they have less possibilities of physical damage.

• With no moving parts there is less energy expended which means longer battery life.

• Solid State Drives (SSD) are not damageable by magnetic fields.

• In Solid State Drives (SSD) computers can pull up the data immediately instead of looking around on a spinning disk.

• Solid State Drives (SSD) are more expensive as compared to regular Hard Drives.

• Compared to Hard Disk Drives (HDD), Solid State Drives (SSD) have smaller mortality rates and are more reliable.

• Data Recovery complicated on SSD.

No matter if your storage drive is HDD or SSD, if they need Data Recovery Solutions then they either need Tier I or Tier II data recovery.

Data Recovery for HDD is easier and is less time consuming.

The primary difference is that standard platter based HDD's can recovered through mechanical means, whereas SSD’s must special technology and algorithm understandings for the individual memory chips and software to try and rebuild the data.

According to eProvided, Hard Disk Drives (HDD) greater in size then 500 GB’s can take a few hours or less for recovery whereas a 64GB SSD could take more then 24hours.

• Logical Damages (Tier II):

written in your storage medium. A damaged storage medium can also lead to similar issues. In both, the file system remains in your storage drive in an inconsistent state and needs proper data recovery support to restore and restructure the data.

A few malfunctions that can seen in your storage medium after logical damage: drives reporting negative amounts of free space, recurring directories, the clicking behavior of your hard drive’s read/write head etc.

• Physical Damages (Tier I):

Data Recovery for a  damaged drive has no other solution then the need for a Data Recovery Company. But, still there are many ways to prevent such accidents. A physical stress in a Hard Disk Drive (HDD) can lead to larger problems then in Solid State Drives (SSD) and this  makes the data recovery process more complicated.

• Physical Damages (Tier I):

Solid State Drive (SSD) manufacturers claim devices can still operate even after dropped from two- level buildings but this is not true in every situation. A  damaged Solid State Drive (SSD) has, in most cases a definite need for a Data recovery company and experts like eProvided.

Data Recovery Technique from a Logically Wounded Drive:

? Consistency Checking:

Consistency checking refers to the process where the storage medium undergoes deep software scans. This process is thoroughly performed with the help of advanced software which enables an educated user to know the logical structure of the disk and the accuracy of its directory and their entries. In every file system a directory must have at least two basic entries i.e. a dot entry that points to itself and a double dot entry that leads to the parent. The software helps to read and correct any issues that may arise and are necessary in restructuring data.

? Data Carving :

When data recovery from the storage device fails from a normal mode data carving techniques are used. This is due to the fact that the desired data no longer has file system allocation information available to identify the sectors or clusters that belong to the file or data.

Data carving usually searches through raw sectors looking for specific desired file signatures, this is because the file system has no information on the size of the file being carved, 

Always remember to ask questions and make enquiries about the company and hard drive recovery software, as these questions can help you to get back your data with safe means and do help your pocket from heavy expenditures.
