The ultimate guide to replace your hard drive

Things you need to take care of before you replacing your hard drive

A hard drive is the computer’s data store i.e. it has all the data required for the normal functioning of your computer as well as the data that you may have additionally stored on it like music, photos and videos. Before replacing a hard drive, all this data will need to be backed up somewhere or if you already have been making backups you will need to move these backups to a different physical location instead of letting them stay on the same hard drive. If however, you are the victim of a failed hard drive and need to recover your data, you can make use of the tools like Wondershare Data Recovery, Recuva and PC inspector etc. to retrieve all that data for you.  Once you have made sure that all the useful data has been recovered and is safe, you can continue with the hard drive replacement process.

Choosing the new hard drive

Data and Power Connector Types

The new hard drive that you are planning on buying should have the same data and power connector types as you previous ones so that it can be attached to your computer or laptop. Buying one with different types of connectors will only create a huge mess for you and you may need to replace that one later on.

Capacity, Speed and Reliability

Three of the most fundamental characteristics that should be kept in mind when buying a new hard drive are capacity, speed and reliability. There is a wide range of options to choose from but you should buy one which is best suited to your needs. If for instance, capacity is not a major concern but you cannot compromise on speed and reliability, buy a hard drive that will cater to your need for faster data transfer speed and reliability.

What you need to do after replacing your hard disk

Testing a new hard drive is always a great way to know if the hard drive came with some fault that is not apparent for some reasons. This way you can return it to the vendor and get a healthy replacement so that you don’t have to suffer later on. To test a hard drive, the simplest thing to do would be to copy a lot of data to it and then copy that data back to a different location. The data has to be large so that the hard drive can be properly tested. Notice the temperature of the hard drive by touching the back panel of your laptop after it has been running for almost an hour. Check for noises or clicking. If anything seems to be odd, report the problem immediately to the vendor.
