Have You Protected Yourself From Potential Data Loss
There are many potential causes of data loss for all computer users ranging from the casual home user who just does a bit of occasional surfing and the odd bit of Photoshop, too the computer super users and computer aided design experts. Typically data loss can occur when a computer starts to experience boot up problems.
If you have been here before then at least you will have a vague or depending on your experience a deeper level of knowledge here, but for many potential data loss scenarios are a new computing horror to overcome, so what typically should we be looking out for?
Computer is working but simply won’t boot up properly: Often this can be overcome by starting your computer in safe mode if you know how, and going from there. But this will not always help as you may be suffering from a software issue or conflict or even possible a hardware issue such as a failing hard disk drive.
Your computer loses its zing and starts to feel very jaded and slow: This could be the result of hard drive fragmentation which can be rectified, or could be a more serious operating system problem. The potential for data loss is possible in both scenarios and the most serious operating system problems are best dealt with by doing a totally clean OS install.
Virus or Malware infection: Computer viruses and other Malware applications, if not properly handled from the start, will inevitably lead to situations whereby a full reinstall is the only option to truly remove all trace of the malicious software from the system.
So what are the options here once the problem has arrived, and how can we avoid any form of data loss when in a lot of circumstances the only answer is to wipe our system and start from fresh?
The best way to avoid data loss in the first place is to follow a simple protocol. Backup your important data on a regular basis. There is simply no good excuse for not doing this as external drives and online backup centers are readily available to all.
External hard drives can be purchased in most computer shops now days and a quick search online for online backup will also give you a number of remote back up options
So what’s the answer when the data loss monster has knocked at your door? Well if you truly cannot afford to lose data, take out the hard drive from the machine and replace it with a new device for the reinstall. This leaves you the option of professional help if all else fails.

Recovering Data From Hard Drives
Overview
Modern computer system hard disks can contain a vast amount of data. So when your hard disk fails, and there are no recent backups available, data recovery is the only option available.
Introduction
A hard disk consists of a number of component parts. Each of which has its own failure modes.
1. Electronics
2. Mechanics
3. Firmware
4. Logical
Electronics
The circuit board on a hard disk is the ‘brain’ of the hard disk and a single component failure will render the drive useless. Data recovery from hard disks with electronics failures will require highly skilled electronics engineers who can to make temporary repairs in order to recover the data.
There are also electronic parts inside the hard disk that are vital for the correct operation of the hard disk and consists of the head pre-amplifier circuit.
Mechanical
The critical mechanical parts of a hard disk comprise of, the actuator arm, the motor and the platters. (There are other Mechanical parts, vibro-acoustic components, filters, VCM Magnets, etc, but these are less critical).
The majority of mechanical failures involve the Head pre-amplifier. Whilst this is not exactly a mechanical failure, the method that the head pre-amp is fixed to the head stack means that when it fails it involves the replacement of the entire head stack assembly.
The next biggest cause of failure is motor failure. This is probably the most serious problem and requires specialist equipment so that platter alignment is not lost when removing and replacing the motor. Main problems with motors are burnt out coils and seized bearings.
Firmware
The firmware area or System Area (SA) is a region on the hard disk that contains the manufacturer’s proprietary information such as
- Grown Defect Maps
- Head maps
- Operational code
- Self test logs
- ATA Password Information
- Security Data
- SMART Logs
- Translator Tables
and many others
For a hard disk to work properly it is vital that the Firmware Zone is error free. Fixing the Firmware on a hard disk is a highly skilled job and requires specialist equipment. Making a mistake when modifying the information in the Firmware of a hard disk can render a drive useless.
Logical
Logical problems are where there is nothing physically wrong with the hard disk and it is fully functional. Logical problems are where data has become inaccessible for some reason, for example, the user has deleted the files, the computer has come under virus attack. The skill set of the engineer requires knowledge of how the operating system that the data was stored on works. Also, an understanding of the file format for different file types so that quality of files can be determined on a bulk and individual basis.

Backup Data Properly
Computer data can be very important to us, especially those of us who make a living on the computer. Over the last several years, the computer has grown on all of us, making our lives so much easier. For that very reason, it’s easy to tell that if we lost our computer data, it would completely destroy a majority of us.
Losing data can be an overwhelming thought to say the least. Computers store data, although machines have been known to fail. Even though the computer has become a lot more reliable over the years, it is virtually impossible to prevent computers from losing data.
You don’t need to take this lying down through, as you can indeed fight back. The ideal way to ensure that you never lose your precious data, is to back it up and keep backing it up. You should back up your computer data at least once a week, with once per day being the recommended way to do it.
In the past, and even some today, the floppy disc is the main method used to back up computer data. Even though they store a small amount of data, they are easy to access, easy to use, and nearly every computer has one.
Those of you who are looking to take things to the next level should look into backing up your entire hard drive. Backing up your entire hard drive is something that everyone should do, as it is indeed one of the best and most reliable ways to backup your computer.
When you create a backup of your entire hard drive, it will copy all of your information, so if something happens you’ll always have your data. Doing a full backup of your hard drive is great, although it can be very time consuming. To make matters worse, it is recommended that you create a backup at least once a week. On the other hand, if what you have on your computer is very important, you’ll find it more than worth the effort and time needed to back things up.
Another way you can back up your data, programs, and files, is to burn them directly to a data CD or DVD. This way, you can select which files or folders you want to keep. If you use CD/RW or DVD/RW disks, you can continue to add information to them when you create a backup. If you don’t use the RW (re-writable) media, then you won’t be able to go back and add more information to the disc.
Burning data directly to discs are the method of backup that most people are using these days, although backing up the entire hard drive is the preferred way of backing up your data. If you plan to use discs, you’ll need either a CD or DVD burner, which you can get for a great price these days. The discs are cheap as well, which only makes this method of backing things up that much better.
Whether it’s for your business or for personal reasons, you can’t go wrong backing up your data. You should always strive to back things up properly, as this will ensure that the data will always be there when you need it. This way, if you computer happens to crash or you lose everything on your hard drive, you’ll always have your backup files to go back to. This in itself can save you a lot of time, effort, and quite possibly even money - just for the simple fact that the files are all but a copy away to restore.
Why You Should Have Data Back Up’s
More businesses and individuals are making good use of online data storage backup as the means of protecting their most important files of data. There are actually some very good reasons to consider this option, whether you have a small business, a corporation, or just want to protect some of those special personal files. Businesses must use backup mass data storage given the plethora of information stored on their systems. Any loss or tampering of this information can mean loss of time, money, vital information, and if enough downtime ensues–loss of customers. Try Data storage
Tape devices often act as Data storage for storage backups. Whole networks are often duplicated periodically and the tapes are put into storage and reused at a later date. Often, just current changes are taped to add to the already backed up information. The drawback to tapes is they can become dilapidated over time.
CD’s and DVD’s are other devices that can be used as backup storage equipment. Data is compressed to have the ability to place more material on the discs and so they don’t fill up as quickly.
USB ports and external hard drives are additional tools in assisting with backup storage. A computer that has been compromised can swiftly be recovered with these tools. That way there is no major loss of data
there is the convenience of being able to access your data from any computer with an Internet connection, well that if you do it online. Online data storage backup is a security protected service, so all you need are your login credentials and you can access your data while on business trips, visiting with friends, or enjoying a vacation. As long as the computer you are using will allow you to read the file formats involved, you are in great shape.
For many people, this is the ideal way to keep important information safe and accessible
