You have stumbled upon this post; it might be because you were researching on ‘data storage’ or it could also be that you simply came across this post. If it is the latter, you might be wondering what is there to actually talk about a sleeper topic like ‘Data storage’. I suggest you, read on…
Your data is the most valuable asset in today’s world and you go to any lengths to safeguard it. Here, the importance of data storage comes into the picture. Hence, devices such as memory card, pen drives, external hard disks etc. are widely used across the globe.
There is no doubt that they all provide a very easy and convenient way to backup data, move, share, store and secure data.However, off lately it is very important to make the data secure. Just in case the computer, server or any other device gets damaged, you could be at the risk of losing some important information.The Hard drive is one such device which is present in the form of a permanent storage device.
This article will help you to understand what a hard disk is, its different types and few myths about data loss.
What is a Hard-Disk?
The Hard disk is nothing but a hardware device used for data storage. Hard Drives are capable of storing huge amount of data. Hence, it is part of your computer systems. Everything that you store on your PC/ laptop in the form of documents, pictures, music and videos is stored on the hard disks.
The Hard disk is often referred as a non-volatile memory storage device which means once the data is stored on a drive it is capable of retaining the data even when the computer is turned off. It is independent on electricity which is somehow a huge advantage.
Hard disks are also known as hard-drive, hard-disk-drive, fixed-drive, fixed disk.
Now that you know what a hard Drive is let’s move on to its different types……….
Types of HARD-DRIVES
- IDE: IDE basically stands for integrated drive electronics also called as PATA drives
Which stands for (parallel advanced technology attachment).
- SATA: SATA stands for serial advanced technology attachment.
- SCSI: SCSI stands for small computer system interface.
- SAS: SAS is nothing but serial attached SCSI.
3 COMMON MYTHS OF DATA LOSS:
Given below are few myths about hard-disk with respect to when data may be lost or when the device might stop working.
- DROPPING DOWN THE HARD DRIVE: Well majority of the people believe that if a hard disk is dropped on the ground from a height,it would start working as if there is something jammed inside the disk, but unfortunately the truth is, the hard disk stops working permanently if it hits the ground surface harder. The internal components may get damaged and that could result in data loss.
- FREEZING AND HEATING THE HARD DRIVE: Freezing the hard disk actually works but only for a short period as freezing may help to rearrange the magnetic coating on the hard disks but it becomes even harder to recover the lost data as the data might be erased forever due to the magnetic material on the hard disk.
- DATA RECOVERY SOFTWARE: There are some misunderstandings about the data recovery software as people think and believe that the software fails to recover the data and is a complete wastage of time and money but the truth is data recovery software helps to recover the files or deleted data provided that it isn’t over-written by any other data or file. Know how data recovery from unreadable USB hard drives is possible.
CONCLUSION: Till now it’s clearly understood that the hard disk compromises several electro-mechanical components and performing any of the above myths can result in permanent data loss.
Thus, it’s very important to handle these devices with extra care and opt for an authentic data recovery software to recover maximum possible data.
