Every data carrier breaks down at some point. The only
question is when….
The moment when a media carrier such as a laptop, USB stick
or hard disk breaks, usually comes unannounced. Panic often dominates at times
like this, especially when the data is not backed up. Intuitively, attempts are
then made to save this data yourself as much as possible. But this often
achieves the opposite effect. This greatly increases data loss. In the worst
case, the data that could have been saved is also lost.
When Googling on the internet a lot of well-intentioned
advice emerges on what to do in such cases. But these advice can sometimes have
dire consequences. That is why we list the 8 biggest mistakes that are made
with data recovery on your own.
1.
Hard Drive Broken? In The Freezer!
One advice that haunts internet forums, for example, is
that a broken hard drive will work again after it has been in the freezer for a
while. This approach is nonsense. Even a properly working disc will fail after
such a treatment.
2.
Solid State Drives (SSDS) Cannot Fail
Unfortunately this is not correct. What is true is that
SSDs are resistant to mechanical damage. This is because there are no
mechanical parts mounted in these media carriers. However, it is not correct
that these media carriers cannot fail at all. In many cases, data recovery can
only take place by removing the individual memory components.
3.
RAID Fairytales
Another big misunderstanding is that a RAID solution would
prevent data loss. RAID itself contributes to the alleged certainty that
results in no backups being made because this would not be necessary. With all
its consequences.
4.
Delete Data? Just Overwrite the Hard Drive with New Files
The more times the hard disk is overwritten, the better it
is to erase data. However, this is a persistent rumor. This myth is not based
on current technological developments. No matter how often you overwrite a hard
drive, the question remains how many sectors have actually been erased.
5.
New Hard Drives Cannot Fail
The number of hours that a hard drive has been actively
used has very little effect on the life of a hard drive. The circumstances of
how the manufacturer's hard drive gets to the user's PC, laptop, or server is
of much greater impact. Also important are environmental factors once the drive
is put into use. Vibrations, shocks and (over) heating limit the lifespan of
the hard disk. We receive as many new drives in our cleanrooms as those that
have been in continuous use for more than fifteen years.
6.
There Is a Vacuum on the Hard Disk
A widely held assumption is that there is empty space in a
hard drive. In reality it is air that is necessary for the hard disk to
function. In the housing of the hard disk, the read and write head floats on a
thin air cushion. To be precise, at a few thousandths of a millimeter above the
disk surface. Thin air could damage the magnetic layer. It is therefore no myth
that hard disks should never ever be opened by users themselves, because this
is only possible in clean rooms. Small dust particles cause the hard disk to
crash.
7.
Manufacturer Is Responsible For the Recovery of the Data
That a hard drive manufacturer would be liable for data
recovery in case of data loss is not true. This misunderstanding often stems
from the frustration of the user. In the event of a defect, the user will be
offered a new copy within the warranty period, but the costs of the
reconstruction of the data will be borne by the user. There is also no
insurance against this.
8.
Easily Exchange Electronic Components Yourself
Because it often happens in practice that the data on the
hard disk is still completely intact, but the electronics are defective, users
sometimes want to exchange these components themselves. This can have fatal
consequences because one does not realize that both firmware information and
all kinds of parameters are partly stored on magnetic disks and in the EPROM of
the electronics. These parameters are unique for each individual hard disk.
This concerns, for example, the correct values of the read and write heads.
Without these parameters, the disk cannot be initialized. That is the reason
why it will not work properly after changing.
These mistakes can be made by anyone. You are simply not a
data recovery expert, right?! Fortunately, you can take help of a data recovery software in case of
data loss.
Data recovery
software will help you in recovery of your data from hard drives, PC,
laptop, CD, Pen drive etc. This software recovers all your data and quickly
depends on the amount of damage done.
So, trying data recovery on your own is not bad, but that
may lead to data loss permanently which can’t be recovered again. Therefore,
use data recovery software to
recover your important data.
