Emergency Hard Disk Rescue
If you have suffered data loss while using your desktop computer or notebook / laptop, there are a couple of things that you need to know in order to ensure that you are able to recover the lost data eventually.
Firstly, you need to determine the kind of failures. Generally, one could classify the failures to be logical or physical.
Typical examples of logical failures:
In some cases, it is rather obvious to decide if it is a logical problem (such as deletion of data, virus attack etc). In more complex situation, one could follow a simple guide to determine the hard disk failure mode easily.
If one is unable to detect hard disk in the operating system or boot up BIOS (normally accompanying by strange clicking or grinding sound), this could be typical hard disk head crash. The cause could be due to power surge, impact or end-of-life wear and tear resulting in mechanical, electrical and material damage of hard disk.
|In the case of logical failures, these are what you should know :|
If you suspect it is a physical failure such as read write head crash, the safest thing to do is to stop work immediately. Attempt to even power on the disk and worse still, run some commercial recovery utility will not get you anywhere, besides increasing the probability of damaging the data platter further. A hardware failure warrants a hardware fix and there is no second way about it.
