RAID Hard Drive Failure Is A Pain

You can back-up and design infrastructure for preventing data loss because of hard drive failures. In addition, you can also take some measures so that the rate of failure can be minimized. There are some tips that can help you with these issues.

Broken hard drives are insane!First, you should have ensured that your server has enough ventilation to prevent overheating. Make sure that you are protecting your system from power surges. Try to avoid running your RAID array too hard when it is excessively fragmented. Your drive set can fail if it works to hard, and too much. Excessive vibration can result in the drives crashing.

Also, take steps to stop the vibration of your server rack if needed. Reliability of drives may vary according to models and manufacturers. As an example, a Western Digital hard drives may fail quicker than a Seagate drive does. A Mac laptop hard drive may be easier to recover than a Windows PC or a raid drive failure. So be careful depending on what sort of storage device you are running.

If you do not have a very tight back up, you should consider setting it up so that a transition can be done from one drive to another. New drives are particularly prone to failing in the first few months of usage because manufacturing defects that are not immediately noticeable can quickly manifest themselves once the drive is put to work. Therefore, it is better to avoid putting brand new drives into computers.

Finally, minimizing the occurrences of laptop hard drive failure must be considered because of cost, data loss and time consumption. Because laptop computers are mobile, they are particularly susceptible undue damage to the hard disk. It is good to watch for this.

It is sometimes impossible that you can prevent your hard drive crash but isim possible to know when it is going to fail. It is important so that you can back up data from disappearance.

Look at these signs:

When you hear clicking or crashing noises, it indicates that you do not have much time until your hard drive is going to fail.

Disappearing Data and Disk Errors: If you notice that you are missing your files and all of your programs stopped working, and you cannot save your documents, it gives the symptoms of problems with hard drives. Does your computer stop recognizing your drive? Well, when your computer is no longer able to identify your drive, you can think that your computer has troubles with hard drives.

If your computer crashes, while accessing files (such as at the time of the boot sequence), it indicates problems with your drive. When you computer is taking more time than requirements during accessing, opening, or saving files it provides the symptom of failure. If you are using an HP ProLiant RAID server and one of your disks happens to fail, it is important that you quickly follow the procedure for replacing the hard disk. Failure to do so can mean all of the data on the RAID array (provided it is at least a RAID 5, 6 or 10 configuration) will be lost. Locking up during the boot process indicates a single hard disk problem in the array if this happens frequently. RAID recovery help is available.

Hard drive failure may occur because of physical and logical reasons. Physical failures happen due to a failure of the electric motor or the drive itself. They can also take place because of a major head crash that is caused by your computer being dropped or jostled while it is running. Logical failures are result of corruption in the file system. If you by accident delete a vital registry entry or format the drive improperly, or if you get a virus, hard drive can suffer problems. The BIOS will identify the drive, but it will not boot. Some specific causes of hard drive breakage are vibration, heat, power surges, physical damage to computer and corrupted files etc.

Watch Your Disk Drive Heads

When a drive faces excessive vibration, the heads can be offset which can cause a crash. Overheating is a primary cause of breaking hard disks. A power surge caused by any factors can result in data loss while reading or writing. Finally, it may leads to computer crash. Physical force, for examples bumping, jarring, or dropping your computer can cause physical damage to the hard drive. Recovering from this is not often simple.

Files in your computer get corrupted for many reasons. If you close a program improperly, turn off your computer before you close files and don’t install new software that can cause files to become corrupted. Computer shut downs because of power failure also create corrupted files, which can damage the hard drive.

Moreover, you should consider that hard disks are mechanical devices and they can get worn out really easily. Keep that in mind the next time you have some hard drive problems.

This drive may crash at anytime.
