How to Recover Data from Undetectable Hard Disk

Losing data due to hard disk drive fail is a very frustrating experience. Most of the time users of the system recover these lost data with utilities built right into Windows. Hard disk becomes undetectable due to following reasons:

·        Firmware corruption
·        Electronic Failure
·        Mechanical Failure
·        Logical Corruption

All the above reasons are responsible for the corruption or undetectable of the hard disk.  Data exists in the hard drive is recoverable or not is depends upon what exactly had happened with the damaged or undetectable hard disk.

Firmware Corruption: Hard disk firmware indicates a software code that embedded and controls the physical hard disk of hardware. The corruption of the firmware that is in the computer’s hard disk causes undetectable or unreadable of the hard disk. If the hard disk is reprogrammed or repaired, the data exist in the hard disk can be recovered.

Symptoms:

1.      As soon as the power is on the hard disk spins up but it recognized incorrectly or not recognized by the computer system.
2.      Though the hard disk recognize correctly by the computer system thereafter system gets hang during the boot process.

Electronic Failure: when electronic fails, it creates problem on the controller board of the genuine hard disk. Therefore, computer system faces problems like electrical surge or power spike that hit the controller board and makes it undetectable to the BIOS.

Symptoms:

·        When powered is on, hard disk does not spin up and it appears dead or unrecognized by the computer.
·        Disk starts to knock, as the motor fails to spin.

Mechanical Failure: Mechanical hard disk failure means the broken parts of the hard disk is denying to do work. The drive makes some unexpected clicking sound when attempt to access the file inside the system. You need not to worry about your data, the data in the hard disk will remain safe but to recover your data you have to hire an expertise. Mechanical failure basically occur when internal component of hard disk goes faulty and the hard disk become inaccessible.

Symptoms:

·        The hard disk makes some clicking sound immediately after the powered is on
·        As the disk is powered on, initiates some music tone.


Logical Error: Logical error is totally different from electrical and mechanical problems. Logical error does not affect the disk physically; it only affects the information on it. So, to deal with the logical error is not an easy task.

Some examples of Logical Errors are accidental deletion, file system corruption, software bugs, viruses and malware etc.

There are some another reason behind the non-recognition of the hard disk:
·        Your hard drive is not configured properly or you may changed incorrectly the BIOS (Basic Input Output System) settings like access mode, boot sequence etc.
·        Disk controller are faulty.
·        Hard drive interface cable are broken down.
·        Incorrect jumper setting.

The BIOS function that is inside our computer system initially tests all the hardware components of the system as soon as the system’s powered is on. Whenever BIOS fails to detect any hardware, that particular hardware becomes unavailable to the computer system. Such kind of activity makes your data inaccessible and one of the reason of data loss.

To solve these problems you have to follow certain steps:
·        Set BIOS setting to default.
·        Verify the jumper setting.
·        Check all the cables are working properly or not.
·        Check disk controllers.

If the above points are checked, thereafter hard disk is undetectable then it becomes necessary to reprogram or repair the hard disk, so that the data exist in the hard disk can be recover safely.

  1. Approximately how much does it cost to repair if it's a mechanical failure? The data will be save? I mean as in the process of repairing would not affect the data in the disc right? =/

  2. You can't easily fix an undetectable HD, take it to the professionals or to its manufacturer (if warranty still available). Once they fixed it and you want to retrieve your lost files, you can download a recovery software here in the web. For me, I'm using this software when I lost a file or deleted it accidentally, sure it'll help you as well.
