Storage is Everywhere in
Information Age
In the age
of information, a lot of invaluable information are stored
in hard disks and removable storage media such as Flash
and Smart memory devices.
Storage can
sometimes fail. Even though modern hard disks are pretty
sturdy, can absorb shocks up to 200-300G, and its Mean Time
To Failure (MTTF) often indicates that the hard disk should
last several years, maybe 5 or even 10 years, the reality
is that hard disks can cease functioning unexpectedly with
little or no warning at any time.

Recovery Considerations
When any data storage media encounter problems, the immediate
fear is always data loss. The first decision more than
often is to ask if the data can be savaged.
The subsequent
actions taken depends on if there are alternatives to
manage the data loss. Regular backups would have much
lessen such impact. Otherwise, the decision to directly
recover the data from the failed storage media will be
a commercial one, of whether the information is worth
the cost of recovery. In other words, the decision weighs
on the value of the data.

Based on
our experience, data can be recovered from 80% of the
storage media. Another 15% will require more intensive
repairs subjected to the availability and delivery of
the replacement parts, which may cause delays in turnaround
time. Only for the remaining 5%, the data is either too
costly or too time-consuming to recover, or forever lost.

Logical Vs Physical Data
Recovery
We do not guarantee 100% data recovery, because we understand
that technology has its limitations. Data Recovery can
be broadly classified as Logical or Physical.
- Logical Data Recovery is usually
carried out at software level, such as recovering files,
directories and even paritions, accidentally deleted
from the hard disk drive, or rebuilding a corrupted
or virus infected boot sector.
- Physical Data Recovery, on the
other hand, can only be carried out by Data Recovery
Specialist, like ourselves, to retrieve data in the
unfortunate event of a hard disk failure. Because this
delicate process requires a certified clean room facility
and specialized tools for extracting the data from a
storage media, in non-working condition.
Physical
repairs are often followed by logical reconstruction especially
if some data is permanently lost due to damaged disc surfaces.
This process is time consuming and costly.

Time
Element in Data Recovery
Do not underestimate the time element in data recovery.
For logical data recovery, losing the data for a week
can meant effectively losing the data for good.
For example,
in Microsoft Windows, a single file either accidentally
or permanently deleted are moved to Recycle Bin. By emptying
the Recycle Bin, the file will be effectively freed from
the associated FAT entry and the deleted file will no
longer protected by the file system. The Operating System
can utilize the released resources to create new file
and the information may be overridden and lost forever.
For physical
data recovery, the data may be permanently lost, if there
are excessive physical damage to the platters, but the
magnetic force is usually strong enough to hold the data
intact except under extreme conditions. It is therefore
highly recommended that in the event of a hard disk crash,
shutdown the power immediately and contact a Data Recovery
professional for immediate assistance.

| Good
to Know DIY Basic Diagnostics
As we now know, when a hard disk crash, it does not meant
the end of the world, under most circumstances the data
can still be recovered with a pretty good rate of success.
After deciding that the data is commercial viable to be
recovered, it is now time to rein in the Data Recovery
professional.
But it
will be useful to know more about your Hard Disk. For
those technology savvy, they may like to do some DIY troubleshooting
themselves. For more detailed description [Click Here]
Next, provide
a problem description by recalling what last happened
during the usage of the hard disk. Information such:
- Is there a blackout or power
trip?
- Are there any error messages
on bad sectors in the system logs before the crash?
- Are there any unusual system
behaviour before the crash?
- Has there been movement of the
computer from one cubicle to another?
- Has the hard disk been dropped
onto a hard surface (physical shock) or man-handled
(static electrical damage)

More information
about the hard disk can be easily found on the labelling
on the topside of the hard disk. It contains the manufacturer
name, the part number and serial number, and the hard
disk capacity. Keep the information handy, especially
when sending in your storage media for recovery.
Last but
not least, it will be even better to know information
about the Operating Systems and the type of file systems
the hard disk is running on.
Armed with
the above information, you can show that you meant business
when dealing with any Data Recovery specialist (including
us).

No
Data No Charge
For Physical
Data Recovery, we are equipped to work in a clean room
environment with specialized workbenches, for repairing
data storage media, recovery of data from damaged media
and if necessary, perform logical file reconstruction.
The chances of successful repair and data recovery depend
largely on the extent of the damage. The recovered data
will be transferred onto another hard disk storage media,
usually of similar (if not compatible) configurations.
For Logical
Data Recovery, we rebuild files that have been damaged,
or corrupted, or accidentally deleted, instead of performing
surgical repair on the hard disks. This requires in-depth
knowledge of a host of different Operating Systems, from
Windows and Mac OS to different variants of Unix and Linux,
and their underlying file systems.
We standby
our "No Data, No Charge" policy, our customer
only pay if the data can be recovered and complete. Payments
will be revised downwards in any instancs of partially
recovered data. Otherwise, we will refund any payments
if we are unable to fulfill our obligations.
