Data Recovery for HDD is easier and is less time consuming.
Whereas, in SSD, due to the complicated but advanced processes of data
data recovery is tough and sometimes impossible.
Solid State Drives (SSD) are slowly replacing Hard Disk Drives
(HDD)and a suitable
example can be placed from the wide range of options we find when we
to purchase a new laptop computer. These choices are now on desktops
Although, the choice between SSD and HDD laptops are
for SSD laptops are slowly overlapping HDD which eventually shows that
State Drive (SSD) will successfully lead the market in the near
with this, data recovery for your hard drive will be more complicated
because data recovery for SSD is a complex process and cost is likely
higher than older versions of HDD’s.
On the other hand, still
many users are unaware about the real
between these two drives and their advantages or disadvantages. Even
we come across various Storage Drives every day but we hardly wonder
it is a Solid State Drive (SSD) or a Hard Disk Drive (HDD). I don’t
it is surprising that people are unaware of Data Recovery and its wide
even from wrecked and dead drives. I didn’t know about data recovery
I completely broke my Thumb Drive and lost all my high school pictures
Well, if you are among those who haven’t faced such
data loss or don’t know if Data Recovery is possible even from
or logically dead storage drives then I suggest you become familiar
Storage Drive and something about Data Recovery; if you are using
then you are always a probable victim of Data Loss.
Hard Disk Drive are an enclosed disk drive that contains one or more
disks for data storage. These drives are non-volatile in nature and
to store digitally encoded data on a rapidly rotating magnetic

ultimately helps in the data storing process.
Hard Disk Drive (HDD) were introduced in 1956 by IBM as a data storage
with a simple motive to maintain their accounting but later the need
and reliable storage device led this simple Hard Disk to a complex and
advanced form like: RAIDs, NASs or SANs etc. The undeniable need of
devices among business organizations and individuals not only
IT industry to produce storage devices with great flexibility and
capacity but they also had to find a better clarification in case of
and unpleasing drive malfunction or data loss. Hence, Data Recovery
like: eProvided emerged to be the solution when data loss strikes.
of Hard Disk Drives:
• Hard Disk Drives (HDD) contain moveable parts like: rotating
platters and moving heads which make HDD weak or sensitive towards any
• Platters used in Hard Disk Drives (HDD) are coated with magnetic
Hence, they should not be 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
• Data Recovery is (in most cases) simple and easy.
Solid State Drives have been marked as a revolutionizing memory device
field of the IT industry and among data storage lovers. The Drive
and non-optical but a solid state semi-conductor promises faster
better physical flexibility towards extreme temperature, shock and
A Solid State Drives are a high performance plug-and-play storage
have no moving parts and contain DRAM or Flash Memory Boards which are
to resist the unnecessary physical vibrations and shock so to provide
free performance even in an uneven environment.
These SSD are designed with a CPU to manage data and are amazingly
other conventional rotating hard disks. Thus, they are highly
server systems where time is crucial.
of Solid State Drives:
• Solid State Drives (SSD) have no moving parts, consists of flash
chips (NAND Wafers) so they have less possibilities of physical
• With no moving parts there is less energy expended which means
• Solid State Drives (SSD) are not damageable by magnetic fields.
• In Solid State Drives (SSD) computers can pull up the data
instead of looking around on a spinning disk.
• Solid State Drives (SSD) are more expensive as compared to regular
• Compared to Hard Disk Drives (HDD), Solid State Drives (SSD) have
mortality rates and are more reliable.
• Data Recovery is complicated on SSD.

Data Recovery for Hard Disk Drive (HDD) and Solid State Drives (SSD)
categorized under two headings: Tier I (Physical Failure) and Tier II
Failure). No matter if your storage drive is HDD or SSD, if they need
Solutions then they either need Tier I or Tier II data recovery.
Data Recovery for HDD is easier and is less time consuming. Whereas,
due to the complicated but advanced processes of data storage; data
is tough and sometimes impossible. The primary difference is that
based HDD's can be recovered through mechanical means, whereas SSD’s
special technology and algorithm understandings for the individual
and software to try and rebuild the data.
According to eProvided, Hard Disk Drives (HDD) greater in size then
can take a few hours or less for recovery whereas a 64GB SSD could
Data Recovery for Hard Disk Drive (HDD):
• Logical Damages (Tier II):
Logical damage is commonly caused by power issues (too much too
of power, power surges, etc.) because this prevents your data and file
structure to be completely written in your storage medium. A
storage medium can also lead to similar issues. In both, the file
in your storage drive in an inconsistent state and needs proper data
support to restore and restructure the data.
A few malfunctions that can be seen in your storage medium after
drives reporting negative amounts of free space, infinitely recurring
the clicking behavior of your hard drive’s read/write head etc.
Physical Damages (Tier I):
Data Recovery for a physically damaged drive has no other solution
need for a Data Recovery Company. But, still there are many ways to
such accidents. A physical stress in a Hard Disk Drive (HDD) can lead
problems then in Solid State Drives (SSD) and this simply makes the
process more complicated.

A logically damaged or cracked Solid State Drive (SSD) has some

data recovery companies have claimed that using illegitimate and free
software can harm your storage device and your data severely.
Furthermore, a recent market study has shown that data recovery
is designed for Solid State Drives (SSD) is usually found ineffective
Thus, it’s far better to consult a data recovery company like:

founder Bruce Cullen states “we are also developing a process to get
NAND wafers and put them back together internally at the microscope
Thus, using software for data recovery on physically damaged hardware
seldom a success, hence it’s best & recommended to consult
and SSD/ HDD recovery experts.
Data Recovery Technique
from a Logically Wounded Drive:
Consistency checking refers to the process where the storage medium
deep software scans. This process is thoroughly performed with the
help of advanced
software which enables an educated user to know the logical structure
disk and the accuracy of its directory and their entries. In every
a directory must have at least two basic entries i.e. a dot entry that
to itself and a double dot entry that leads to the parent. The

? Data Carving :
When data recovery from the storage device fails from a normal mode
techniques are used. This is due to the fact that the desired data no
has file system allocation information available to identify the
clusters that belong to the file or data.
Data carving usually
searches through raw sectors looking for
file signatures, this is because the file system has no information on
of the file being carved, the current methods involve specifying a
of data to “carve” upon finding the desired signature.
