Desktop Hard Drive Data Recovery:
Datlabs Data Recovery Services can repair and recover data from All makes and manufacture of failed, faulty, damaged, crashed, inaccessible and clicking Desktop Hard Disk Drives With Datlabs unique technology you get the best possible opportunity to retreive lost data : -
Desktop hard disk drives are manufactured in a 3.5 inch form factor. They contain one or a number of platters having magnetic properties suitable for non-volatile data storage. Modern platters have high area storage density capability typically accommodating platter capacities of ; 500 GByte , 1TByte, 2 TByte and above.
Pre-formatted tracks or cylinders are laid down in manufacture and these control the operation of the hard disk drive in a changeable environment. Read/write heads are attached to an actuator store and retrieve data under the control of the operating system.
Failures can occur often as a result of damage to the control electronics, motor, platters or the read/write heads generally due to misuse or extended use of the device beyond its design life. If you require assistance or guidance:-
- Clicking Noises
- Not recognised in the BIOS
- Drive motor and platters not spinning.
The majority of electronic problems can be rectified and the stored data retrieved.
Mechanical failure of the read/write heads or motor is often associated with damage to the stored data. In the majority of cases this is not extensive. Basic component substitution will often render the hard disk drive operational and the data can then be extracted and repaired. In some cases however the control data is damaged beyond repair and data extraction is not possible without complex reprogramming and rebuilding processes.
Do Not run or attempt to run repair utilities as this will often exacerbate any damage to the stored data.
General info to help diagnose your problem:
There is a difference between an operating system crash and a hard drive crash.
If your operating system crashes, whether you are using Windows, Linux or Mac,
then your data will , in most cases be available following a careful operating system reload.
If the hard drive itself malfunctions, then you will need the services of a data recovery company.
In both cases your data is not going to be made accessible without remedial work being carried out.
Determine what is Causing the Crash:
The first thing you need to do is figure out if the crash is caused by a physical or logical failure. If your computer crashes, it simply will not boot to the operating system. You can get the same errors if the crash is caused by a physical or logical failure. If your computer will not boot and you hear a grinding, clicking or whirring noise, that is a good sign that it is caused by a physical drive failure. At this point you should stop trying to boot the computer and do not try to reload the operating system.
Physical Hard Drive Failure:
If your hard drive crash is caused by a malfunction of the hard drive itself, there is still a very good possibility that the data is still intact and accessible. You will generally know if it is a physical failure by the noise the drive will make, or the lack of it. in most cases you will hear a clicking, clunking, grinding or whirring sound coming from the hard drive. Do not mistake the sounds for a malfunctioning cooling fan. Carefully open the case and listen close to the drive.
If you can still boot the computer but the drive is making a lot of noise, you could still get an image of the drive or clone it to a new drive but this is in most cases a risky option. Datlabs advise that in these cases you do not try to start the computer and copy the files to an external drive because that may be too much stress on the failing hardware. The best bet is to remove the hard drive and put it into a different system to retrieve the important data from the drive.
If you can retrieve the data, great – problem solved right? Now all you have to do is buy a new hard drive and reinstall your operating system and all of the applications. That is not a fun task. If you were able to retrieve the data, you may still be able to take an image or clone of the drive and transfer the image to a new drive.
It is true that today’s hard drives are much more reliable than they were 25 years ago when the personal computers hit the market, however they are still gold medal winners for the most unreliable component in your computer .
If the physical hard drive crash is so bad that the computer will not boot or another system cannot see the hard drive, then you may need to send the drive out to Datlabs.
Logical Hard Drive Failure
A logical failure occurs when the hard drive is healthy but you cannot boot into the operating system. This can be caused by many different factors. A virus, system driver conflict, human error or a software malfunction can cause a logical hard drive crash. When this type of failure happens, imaging or cloning the computer will do no good. Do not try to reinstall Windows or run the useless operating system tools like CHKDSK because those tools can just make matters worse.
You will need a software data recovery solution to retrieve your data.
Just because you cannot access your data on a crashed hard drive does not mean that it is not still present on the drive. What you do from here depends on the importance of the data that is stored on your computer.
If you are like most people in this technological age, part of your life is stored on your computer and that data is important send it to the professionals i.e. Datlabs
