RAID Systems are an array of hard drives that work in front of the
operating system as one unit. They are very reliable and provide a huge
space of storage. They are considered a system that hardly fails, yet if
there is a problem with them, a chain reaction or human errors might
affect the access to the data.
We have recovered data from all different types of systems such as
RAID, level 0-53, among others. Each system has its peculiarities, yet
the common causes of failure are physical damages in the discs or in the
bands.
Damage to the bands is not seen frequently, however, it does happen
and it is a software issue which the system is not capable to solve on
its own. External intervention to find and reconstruct the bands is
needed.
Physical damages in hard drives happen 2 to 3% a year. The problems
that affect the hard drives in the RAID system are the same as the ones
that affect any other type of hard drive. These could be virus attacks,
erased data, improper installation, extreme temperatures among others.
In the case of failure of one hard drive in RAID 5, we simply have to
replace the damaged drive and the system will automatically rebuild the
information in that drive. However, if another hard drive gets damaged
in the process, or 2/3 of the system fails, self correction will not
take place.
Human errors are also another major problem that could account for
additional damage in the RAID 5. We should always change a wrecked unit
immediately; otherwise, procrastination could be costly.
Please consult our experts about any problems with your RAID, we will
put all our efforts and experiences helping you resolve the problem in the least possible time.
