Data Loss Stages
In this article, I will explain how data loss occurs and get worse with some very common mistakes. I will also talk about different stages of data damage by human mistakes and natural disasters.
Data loss will happen one or two times in life. There are different ways data loss can happen depending on the kind of storage device. A USB device will be the cause when the USB port breaks. An SD card will get corrupt or get formatted. A CD or DVD will get scratches and won’t read anymore. A hard drive will have variety of problems which I will explain in more detail in the following paragraphs. A phone or iPhone will make us suffer when a software update will ruin everything. Sometimes we accidently format or delete important data. A child will destroy all the data by pressing a wrong key. Some times a hard drive will physically fail and will make things terrible.
Now I will talk about something every important. A hard drive can physically fail. When I say hard drive that means I am talking about a hard drive from Apple computer, drive from a Windows laptop, hard disk from a personal or business server, an SSD drive from any desktop or laptop computer. When a hard drive fails, it could be one of the few problems. It could be a bad electronics board which is called PCB. The drive can have a failed motor, firmware corruption or read / write head failure. Traditional hard drives have moving parts like platters and heads. Old hard drives have one head and one platter. As the technology grew, the number of platters and heads increased. Now drives come with 4 platters and 6 to 8 heads. So as the number of moving parts increased, the risk of failure also went up. Imagine if there was one head and one platter at one point and now there are multiple parts inside the drive, the risk of failure went up several times.
When this happens, it is very important to understand one thing and that is, take the hard drive to a data recovery lab where the data can be rescued for a much lower price and the risk of losing data permanently may be tremendously reduced. This is a fact that many end user don not understand. They try different things and this make the situation worse, even keeping the drive for a long time make it worse too. I have seen many cases where different computer repair people tried to recover data without using proper tools and made the recovery impossible. So my advice in this case is, when a hard drive gives problems and the data is important, it must be taken to a hard drive recovery professional place to save big time trouble and cost.
There are some other important precautions that must be exercised before it’s too late. For example many people update there iPhones and iPads when they see an update alert. They don’t know the consequences if the update process fails which unfortunately happen most of the time. Therefore it is important to first backup all the data and then run update because in case of software corruption the only way to bring the phone back to life is to restore it to factory settings and there is no way to recover such a phone that has been reset to default. One can imagine how dangerous it is to update a phone without having it backed up. A lot of people think that when data is deleted or the device is formatted, it cannot be recovered, this is not true of course it is sometimes possible in case of modern drives where the device has some feature that allow no recovery. One more area that can save the data is, when data is deleted for any reason, it is very crucial not to use the device because using it will write data to the storage device which might overwrite the old data and this it is destroyed permanently.
In this article, I explained about some the most important factors that can avoid losing data permanently.
