Symptoms of Hard Disk Failure

Most Common Symptoms of Hard Disk Drive (HDD) Failure

This section deals with the most common symptoms of hard disk drive (HDD) failure what primary steps you need to take before taking the hard disk to data recovery specialist company. The most common symptoms of hard disk failure maybe one or a combination of any the following listed below:

a) Hard disk drive (HDD) makes an occasional or repetitive clicking sound;

b) Disk powers up, but then spins continuously with a loud noise;

c) Hard drive makes a continuous clicking sound;

d) There is a scraping noise when the hard drive powers up;

e) BIOS says operating system not found.Hard drive unit powers up, but drive won’t mount;

This is what we call a “physical internal hard drive failure”. Mechanical hard disk failures are caused by physical damage to internal components of the hard disk itself; e.g. the read/write head, motor, logic or printed circuit board (PCB), hard disk platters, and/or actuator arm. The most common solution to recover data from a physically damaged hard disk is to identify and replace the damaged components in a certified ‘clean room’ environment. Zoo Computer repairs Can Help with your Computer Problems!. If the damaged hard disk is exposed to normal environment, microscopic dust particles on the surface of the platters will disk recovery almost imppossible. Therefore, if you hard disk is clicking or makes an unusual noise, do not be tempted to open it to see if anything had got “stuck” inside. You will just ruin any prospects of a successful data recovery by a qualified technician. Visit BuySellRam to help you sort out this problem.

a) Hard disk drive does not display any sign of power;

b) There is no sign of the drive ‘winding up’;

c) Hard drive powers up, but then suddenly powers down;

d) Your computer reports disk error;

e) Hard drive won’t spin up when turned on on and is not recognised by the computer;

f) The system is extremely slow and it takes a very long time to load a program, access a folder or convert a file, e.g., from pdf to html;

g) The system hangs during the boot process does not go anywhere;

Any of the above symptoms indicate an electronic failure. This typically occurs when an electronic surge or power spike knocks out the disk’s controller board or fries one of the chips on PCB thereby preventing the hard disk from spinning up and making it impossible for the computer to recognise it. People wrongly assume that if they buy an exactly identical hard disk, they can just swap the PCB and then expect the electronically faulty disk to work like a dream! WRONG! Please note that head positioning information and translation module are stored on a chip which is called “firmware”. Almost always two exactly identical hard drives will have different firmware revisions. Therefore swapping the PCB can can actually damage a perfectly healthy disk giving it the wrong instructions on where the data is and how it can access the service area (SA). This will cause the hard disk to “click” hence damaging the head assembly of the hard drive. DIY data recovery must be avoided if you have lost critical data. Just call a Data Recovery Lab technician on 0207 516 1077 from a mobile phone or a land line and we will be able to offer you the best advice on what your next move should be.

a) Files inaccessible despite hard disk spinning;

b) The computer automatically starts scanning the hard disk at start-up;

c) The computer shows a menu of different start-up options including safe mode;

d) When the computer has completed the boot-up process, you no longer see your files in their usual places and it looks like all your files have disappeared.

The above symptoms are indicative a file system failure or corruption. File systems are essentially “data containers” which is used by the operating system to store data on a hard disk or memory stick. Examples of file systems are “NTFS” for Windows, “FAT32” for Windows and Apple Mac OS, “HFS” for Mac OS and “Ext1” “Ext2” for various Linux distributions and NAS hard disks. File system corruption can happen as a result of sudden power cut, electro-static discharge, virus infection or bad sectors in hard disks and memory sticks. Again DIY data recovery must be avoided if the inaccessible data is critical. A Data recovery techncian can help you and advise you on best course of action. Normally the rate of success in these circumstances is close to 100% as long as it is handled by a qualified data recovery technician. Call 0207 516 1077 from your mobile or landline for further details or help.

a) No boot-up disk is available;

b) The hard disk spins up when turned on, but is not correctly recognised by the computer;

c) The hard disk spins up but is not recognised at all by the computer;

The above symptoms point to what is known as “firmware failure”. Firware is essentially the software that controls the physical drive hardware. If it is corrupted, or becomes unreadable for any reason, then the computer can not interact correctly with the hard drive. Addressing firmware issues is a specialist data recovery job that requires the hard drive ROM on the PCB to be reprogrammed using special equipment. Data Recovery Lab are among the very few data recovery companies in the UK who have access to specialist equipment that allows them to guarantee a successful recovery from this kind of problem.

Whilst he above list covers the majority of common symptoms of data loss, it’s by no means an exhaustive list. If any of the above symtoms apply to you, just do not panic! The best course of action is to switch off the computer or power down the hard disk and call a data recovery specialist at Data Recovery Lab on 0207 516 1077. It is important NOT to power up the computer or the hard disk as this may cause further damage. Do not experiment with DIY data recovery software if you data is critical and you cannot afford to lose it. Our engineers will advise you further on what the best course of action is. With a highly qualified team of data recovery technicians since 2001, we will be able to help you with the recovery of all your data and copy the recovered data onto a healthy portable hard disk and give it to you.
