Hard Drive Data Recovery
Years ago, memories were preserved in photo albums and
scrapbooks. Personal information was stored in binders and
folders. Now with newest computer technology, most of the personal
information and valuable memories are stored in digital format. All
this digital data is stored in a hard disk drive of the computer. A
hard disk equipped with moving parts and other mechanisms may fail at a
certain time. Although solid and stable hard disks with more
reliability have entered the market, yet the cost is still beyond the
range of the average user would expect. Hard Drive Data Recovery
from a damaged or faulty hard disk drive is not an easy job. If you
are conversant with diagnosing and connecting/disconnecting the hard disk
drive inside your PC, these suggestions can help you in your data
recovery.
Most of the user grade hard drives that were sold in the past five
years have a predictive failure function called SMART (self monitoring
analysis & reporting technology). This function can be enabled
easily on most computers by entering the system setup BIOS. The
SMART will display a warning during boot-up if any disk drive problem is
detected. Then you should back up the data immediately and replace
the faulty disk drive.
Computers operating on Microsoft Windows have an event log which
also can show messages about any problem, the most common one about faulty
hard disk being "windows has detected a bad block on device". When
this message is on, a blue screen with corrupt data and slow operation can
be observed. Immediate back up of your documents is critical at this
stage. You can use an external hard drive through the USB or fire
wire for back up of your data if the faulty disk can still be accessed
through the system. If the faulty hard disk can't be accessed,
offline access can be the next choice.
If
there's another computer, you can attach the faulty hard disk to it as a
secondary drive and then copy the data. Or you can install the
faulty drive in an external hard drive case and then extract the data
through the USB or fire wire. If the system can't copy the data, you can
try software recovery.
Data recovery softwares
If the hard disk drive can still be accessed, data recovery
software can scan it to map and identify those files that can be restored
successfully. It then displays a list of the recoverable files to
the user's selection and recovery. Data recovery softwares are available
online for free download or purchase at a cost of a few hundreds of
dollars. If the hard drive cannot be accessed by the computer or is
totally non-operative, professional data recovery is the final choice for
data retrieval.
Data Recovery Services
If the data on a hard disk that can't be accessed is absolutely
necessary, the job may be entrusted to a professional data recovery
concern. These people have the requisite equipment and expertise for
data recovery from hard drives in any condition. Such recovery
services may cost from a few hundreds to some thousands of dollars,
according to the methods of recovery and amount of recoverable
data.
Proactive action to
secure data
Safeguarding the data stored in a user grade
hard drive has to be a proactive undertaking. Backups at regular
intervals and monitoring of impending failures can enhance and secure data
availability for a considerable period. Installation of RAID, if
supported by your computer, will also help in protection of
data.
