Working with huge amounts of information? You know the panic moment when you realize that you need some files that you deleted a long time ago. This is the topic of this article : Recover permanently deleted files. 1st lets start with some general data recovery tips, valid for all type of data devices, PC’s, Mac’s, phones.
Most laptops and even desktop computers come with just one hard drive. In such case, a crashed hard drive can be a real disaster. Not only do you lose access to your operating system, but you also lose your pictures, documents, videos, application data, and everything else that was stored on the computer. A free partition editor, such as GParted, allows you to create extra partitions on a single hard drive and thus separate the OS and programs from data. The newly created partitions will be located on the same physical disk, but the extra layer of separation between them gives you a useful protection against damage caused by human error and malware.
If your Mac is starting up and you see a file icon with a question mark, or Windows gives you a pop-up that says “Windows detected a hard disk problem,” you’re looking at a potential drive failure. If you’re dealing with data that you absolutely cannot afford to lose, seek professional help like at an Apple Store or professional data recovery service. If you just want to try to get back a few specific files, or get the device running again, here’s what to do.
While magnetic hard drives (platter based) are more susceptible to this kind of failure, it may happen to some SSDs too. A mechanical failure is when there is something physically wrong with the drive. Wear and tear over years of continued usage, mishandling or dropping the hard disk, breaking or short-circuits in internal parts can be reasons behind such damage.
Having covered the ‘deleted data’ section of data recovery is all good and well, but what happens if your drive is not even being detected by your machine? Or your machine can see the drive, but just hangs when you try to access it? What about if the drive is completely dead and won’t even spin up? Let’s briefly cover the main components of a drive, see which components can fail, and what symptoms each failure might exhibit. PCB: This is the (often green) circuit board attached to the bottom of your drive. It houses the main controller (the equivalent of your computer’s CPU) along with many other electronic controllers. This is the interface that turns your 0s and 1s from the platter into usable data that your computer can understand.
Secure and reliable data backups are best done in the cloud. Use a reputable cloud service such as Google or Amazon to mirror your data from your computer to a secure virtual server. Cloud storage is very cheap and provides you with risk protection through automated backups, so set your data to back up automatically. You can also use external hard drives to create backups of your backups for extra peace of mind. The first line of defence for a computer should be a login PIN number, which offers a layer of protection against theft. Another tactic is to install (and update frequently) a firewall program and a well-regarded antivirus and malware utility. You can also encrypt your data, which makes it nearly impossible to read unless in possession of the encryption key. Update the OS frequently to pull in the latest security patches and use multifaceted tools that will warn you about possible phishing emails, unsecured websites and other hacking attempts. Recovery should always be seen as a last resort that’s used to pull the most important data. It’s best to treat a laptop or desktop as simply a gateway for reaching the internet and a way to power software. With the cloud, there’s no longer any reason to use a computer as a storage device. So, if something goes wrong with the machine, then simply buy a new one and dive back into work.
