Imagine you are doing your office work or school work on your machine and you want to view some saved documents on your external hard drive. On connecting it to retrieve data you realize nothing happens. The hard drive is not working. The first reaction would be panic. However, you do not have to panic because you can still salvage data from your drive. You can try doing it before you call an expert for help.
Some common causes of loss of data include software related issues and fault in your hard drive. Sometimes you can solve the problem by yourself while in other complex situations you might require professional data recovery services.
Recover data with software
When one is handling software data loss, avoid using the hard drive in question. Every time one connects the hard drive he or she loses chances of recovering data. The issue of software mainly arises when the drive deletes data. Shutdown your machine with the drive that you deleted data from so that it is safe then make its clone. A person can clone your drive in a number of ways. Scan the clone using various recovery programs. Some recovery programs are free while others you have to pay for them. Recuva is free recovery program that is quite effective. Alternatively, one can use Zero Assumption Recovery if the individual is willing to part with a few dollars.
Recovering your data with hardware
If a machine is not even detecting your drive then the problem could hardware related. Sometimes your machine can see the drive but it hangs when you try to access the drive. Other times the drive is dead completely and it does not even spin. In such cases, the drive is faulty or some of its components have failed. Thus, it is important to understand the parts of a drive and the symptoms they exhibit when they are faulty.
A drive that is not spinning at all
If a drive does not spin at all one can recover data if only the person is willing to put in more effort and time. A PCB problem exhibits itself when the drive does nothing when you put on power; that is it does not make noise at all. If you have an older drive you can just look for a corresponding PCB from another corresponding drive and it will work. However, newer drives use a complex technology. In such a case, one needs to replace PCB.
If your drive is spinning and making clicking noises
It indicates a serious failure and shows that head or heads have failed. It could also indicate platter damage. In such a case, it is advisable that you hire a data recovery expert to fix the problem. The drive needs to be opened in a clean place and a head replacement is done. Just leave the drive as it is and call a professional right away.
Drives that hang
If the drive spins up and the machine detects it but hangs immediately then it shows degradation of the magnetic media. The problem is a common one and it happens often. It shows that the drive is trying to read some bad sectors but it fails and hangs. Hire a data recovery expert to correct the fault.
