DATA RECOVERY FROM A
FAILED HARD DRIVE
Early Signs of a hard disk failure: What to do when a hard drive fails
Any hard drive, internal or external, may experience failure or sudden
crash without any warning but on most occasions, there are warning signs
that will let you know when to take action. Changes in performance,
intermittent failures, or unexpected blue screens are all major signs
that the hard drive may be dying out permanently. The most obvious
warning sign with a hard drive is unusual clicking, grinding, or
In practice, the term hard drive crash often refers to both mechanical
or electrical failure and logical failure. Electro-mechanical crashes
are the worst, it requires professional help of
data recovery company such as Data Recovery
Doctor as data recovery programs won’t help.
Using data recovery programs may even further damage your hard drive
geometry and partition and make the condition worse.
If you see any of the following signs while using your computer, you
must seek the help of a data recovery professional otherwise you
may lose your valuable data for ever. This can be disastrous and
Sign 1 – You hear high-pitched whining,
loud clicking or grinding noises coming from the drive:
Note that a normally operating hard drive will make a
smooth "whirling" sound as is spins up or down. But if a drive has a
grinding or clicking noise (the Read/Write heads scraping too close to
the magnetic platters), then your hard disk is unwell and you have to
rush to a data recovery company.
Sign 2 – You see the infamous "Blue Screen
of Death", repeatedly:
BSODs (Blue Screens of Death) are actually called "Stop" errors and they
only appear when your computer is experiencing some severe software or
hardware issues. Quite often BSODs can happen due to the fact that
Windows is unable to read data from certain areas in your hard drive
because data is trapped in bad sectors of your hard drive.
Sign 3 – Your computer becomes very slow
and keeps re-booting and does not boot to Windows correctly and displays
various troubleshooting options including safe mode:
This means your hard drive has developed multiple bad sectors and does
have faulty, inaccessible areas.
Sign 4 – Your system locks up:
Your computer suddenly comes to a halt. Your mouse and keyboard seem to
Sign 5 – Error message: "hard drive is not
You may be able to restart and get it to boot into
Windows a few more times but this error is certainly a sign that your
drive is very close to death. And by the way don’t try to format the
drive! You will lose all your data!
Sign 6 – Error message: "Boot Disk Failure
or Operating System Not Found" or in the case of Apple Mac
computers, a "?" mark
appears and stays there for ever:
If you have checked the CD/DVD trays, USB ports or the
floppy drive in your computer to ensure no disk is left inside or
plugged in and you still see these messages, then your hard disk has
What To Do:
1) First, don't panic! Just stop using your computer
altogether. Turn your machine off. Do not attempt to use different data
recovery tools downloaded or purchased from the internet to recover data
as this can damage the hard disk and make the data recovery more
difficult as they write some information onto your hard drive. Also
never open the cover of a failed hard disk drive in an attempt to
repair, salvage or recover data. This can lead to an unsuccessful
attempt by a data recovery professional. Speak to a data recovery
technician by calling 0800 8402131
