Data Recovery

Dos And Don’ts Of Data Loss

Data loss leads to panic and chaos to many. What many people do not know is that with the right steps, it is possible to recover any lost data from your PC or laptop. In cases where the hard drive is still available and active, you have some options to recover lost data on your own. If however the hard drive is mechanically damaged, only a professional can help you get the lost data. Read on to get information on what to do and what not to in case you lose data.


  • Contact a professional if you are not sure of what is needed to get your lost data. If you have a backup machine, research and learn basics of data recovery before trying to recover it from the spoilt PC.
  • If you do not have any experience with computers, it is advisable to get someone with experience to guide you on what to do. This is so if the data in the machine is of high importance.
  • Get data recovery tools online and use the trial free versions to find out if the lost data is still available. If the trial is successful, you can invest in the full software to recover your data.
  • Do not try to save data on the external drive or backup to check the files readiness and integrity. In many cases, it is possible to copy the files but if the issues are related to corrupted OS.
  • Check your critical data, photos, and files from time to time, to ensure they are safe.


  • Never try to load up a recovery software on the drive or partition with the lost files. It will in most cases lead to overwriting making it impossible to recover the lost data.
  • Avoid temptations of opening the PC or laptop to check the inside components or the hard drive. There is nothing you can do by DIY at this moment. It will be safe and better if you take the machine to a professional who will repair the hardware in a clean and safe environment.
  • At any moment of data loss, try to stay calm and consider all options before deciding on what to do. Panic and rush will make you do things that make it harder to recover your lost data.

Benefits of using USB flash drives

USB flash disks are a common way of data storage. Their portability and versatility make them the best option for many. They are categorized as high quality because they can last long. This is made possible because they do not have movable parts. Compared to other storage devices like the hard drives, they are more resistant to tear and wear. This article will outline more benefits of USB flash drives.



Their small sizes make it possible to carry them anywhere anytime. You can easily attach them to a chain or sip them into your cloth pockets. Mostly they are between three to two inches. Some come in large sizes like the novelty designs that are preferred by a certain group of buyers. In addition to the durability, they are more suitable for carrying around.


They carry a memory of 1GB to 128 GB. Prices depend on the size. Like for instance, the 1GB ones are cheap, suitable for simple files and light storage. If you want to run a program or backup, get a USB of a higher memory capacity. I would recommend the use of 32 GB USB drives for high load jobs. With larger sizes, you will be able to store more, like, movies, photographs, and music.

Transfer speed

Regarding transfer, they are way better compared to other storage devices like an SD memory card. A 3.0 USB, for example, transfers files at a speed of 7.8 gigabytes per second. Such speed is impressive compared to 312MB of an SD memory card.


This is the standard option to connect to all storage devices and electronic devices. They are compatible with all PC and laptops. Almost all netbooks, desktops and laptops are built with ports to insert the USB. There are other types of USB which can read memory cards.

Purpose made applications

There are numerous applications and programs built to run from the USB drives. Software applications like web browsers, image editors, office software and games can be operated directly from the USB.

Lower power

USB flash drives are built to use little power. This is because they do not have moving parts or motors. Compared to hard disk drives, they consume little power.…
