When it’s time to upgrade to a new hard drive, consumers end up going with capacity and performance while the reliability factor is often taken for granted. A recent statistical survey by a Russian data recovery firm ‘Storelab’ came clean on HDD failure rates. One important finding of this study was the average lifespan of an HDD can vary from 2.5 to four years irrespective of the warranty period claimed by its manufacturer.
Hard Disk Drives undergo intense technological development and are designed with a certain degree of reliability. If you have started using your brand new hard drive, then every operation you perform tends go smoothly as the drive is empty or near-empty. When the storage space on the drive fills up due to heavier use and there is an increased density of data stored on the drive platters, you have good chances of a failure. The frequency of these failures depends on the use of hard drives. If your drive is always in continuous use for longer periods, then matters could become worse more quickly. In such circumstances, you may suffer from a premature drive failure.
In due course of time, you may face several issues as you start using your hard drive and before getting an outright crash. A few of these problems are discussed below:
Physical Drive Errors
A physical error may indicate a bad sector or spot, which typically results from physical damage to the hard drive. If you bump your computer or drop it down to the floor, the damage could be severe. As the drive consists of mostly mechanical parts, any wear or tear would bring the drive close to the possibility of a mechanical breakdown.
Logical Drive Failures
Logical drive errors are marked by the inability to read or write files to and from the hard drive. These errors may also correlate to application or software conflicts. This happens when the two copies of file allocation table (FAT) on the disk do not match or when there is incorrect metadata related to clusters stored on the disk. These are generally an outcome of disgraceful system shutdown or abnormal program termination.
One of the biggest fears concerning drive failures is loss of business files and documents. There is no definitive solution to prevent hard drive failures. However, data backups are a good defense against these catastrophes. Having a recent hard drive data backup is paramount for saving yourself from an unexpected episode of data loss. In case you do not have backups and your hard drive does not display in the computer BIOS, you might opt for hard drive recovery services. They use proprietary techniques to recover data off a failed or damaged hard drive. In case your hard drive is showing logical errors, you can go for a commercial hard drive recovery software. These professional tools do a good job of repairing file system corruption on the drive and extracting all pieces of recoverable information absolutely intact. You need to deal with the issue at hand by making the right choice.
