also have at our disposal some of the best RAID recovery technicians
in the market today. We have the ability to repair your RAID array
even if you have dropped 2 or 3 drives or if you are suffering some
form of physical drive failure. In fact just about any data loss scenario
you can think of we have faced it and successfully recovered valuable
company or personal data. We have not just one but a team of specialists
dedicated to working on RAID failures.
Lets take a second
to explain the different types of RAID setups. Please do your best
to identify your setup, this will aid our technician give you accurate
information when you discuss your recovery with him.
In a RAID 1 (known as mirroring), each disk is an exact duplicate
of all other disks in the array. During the write process data is
sent to all disks in the array. However, when a read is performed,
it only utilizes one disk. A RAID 1 array normally contains two disk
drives. It is however possible to have more then just 2 drives.
RAID 2 is rather obscure array type, and is not widely used. It is
more efficient in regards to space then RAID 1, but there are other
more effective RAID levels that overshadow the RAID 2. Instead of
using a basic parity to check data, it uses a system called a "Hamming
Code". A Hamming code is a bit larger than a parity, so it takes
up more disk space, RAID-2 is the only simple RAID level that can
retain data when multiple drives fail.
RAID 3 is defined as bitwise, striping with parity. Every read/write
to the array will access all drives in the array simultaneously, regardless
of the type of access During a write, RAID 3 stores portions of each
block on each of the drives in the array. It also computes the parity
for the data, and writes it to the parity drive. This drive is often
referred to as the "Hot Swap" RAID 3 does have some configuration
limitations. The number of drives in a RAID-3 configuration must be
a power of two. The most common array setups will have either four
or eight data drives.
RAID 4 is described as block-wise striping with parity. In this RAID
parity is always written to the same disk drive. This creates contention
for the parity drive during write operations. For reads, and writes,
RAID 4 will perform much like a RAID 0 array with an equal number
of data drives. These RAID types are often overshadowed by the better
performing RAID 5 Array.
RAID 5 is one of the most widely used configurations available. It
is defined as blockwise striping with parity. This array differs from
RAID 4 because the parity data is not always written to the same disk
drive. Parity is in fact split up over all drives in the array. This
allows for faster performance during multiple read/write operations.
This makes the RAID 5 ideal for business level use where multiple
clients are accessing data at the same time.
As you can see
there are a multitude of configurations for RAID arrays and we have
worked with all of them. We have even been successful recovering data
from servers that have water or fire damage, power surges, lightning
strikes, you name it we've seen it.
We provide forensic
data recovery services for RAIDs. Be it for legal proceedings, or
maybe you want to find out how your employees are using their computers.
You can rest assured knowing all client data and contact information
is kept completely confidential, and covered under a strict non-disclosure
agreement. Your privacy and security are our top concern.
team is very skilled at repairing drives that have some sort of physical
damage as well. Any number of issues can cause a physical disk failure,
problems such as clicking or tapping sound emanating from the drive
or if the drive will not power up and spin, even hard disks that have
been damaged by fire and water. Our repair technicians have over 20
successful years in the data recovery business and are ready anytime
day or night to make sure you get your valuable data recovered in
the absolute quickest time possible. We offer a full class 100 clean-room
for all physically damaged hard drives. You can rest easy knowing
your drive is in the proper hands.
extremely important to be well informed when choosing a data recovery
company. It's important to choose a company that offers you peace
of mind and a few basic terms and conditions... LDR offers all of
