PCs are used in almost every facet of human life in this modern era. Technology has changed the world and as such the world has grown increasingly reliant on the personal computer to store and retrieve data. In fact, some companies and individuals are almost completely digital now, with almost no paper trail at all. This creates an issue, however. Data loss is a very real problem for individuals and companies alike.
Is data loss inevitable? Absolutely. If a person or business doesn't regularly back up their information, then data loss is very likely to happen at some point. No hard drives are immune from failure, whether the issue is on the hardware side of the software side. If even one hard drive fails, a person or company can lose a significant amount of data in an instant.
Luckily, there are companies that specialize in data recovery. Many times, in the event of either a physical or logical disk failure, the data can be recovered if proper steps are taken. It is possible to fix both hardware and software problems with hard disk drives using the techniques that these data recovery companies have mastered over the years.
Hardware problems pose a special set of risks, because depending on the problem, every time the drive is accessed, more damage can be done to the disk, creating unrecoverable data. Typically, to fix a hardware failure, either spare parts will be used to repair the faulty parts on the original drive or the platters will be taken out of the broken drive and put in a known working hard drive assembly. There are also other techniques that companies employ to fix hardware issues, from literally freezing drives and attempting to recover the data, installing the drive in a known good PC as a non-boot partition, and trying to get the raw data off of the drive.
Software issues, such as logical issues can typically be a bit easier to fix than hardware issues. Companies typically have pieces of software that can be used to either rebuild the file system on the faulty hard drive or they will try to pull the raw data off of the hard drive and use a program to reassemble the data into usable bits.
Whether a disk has hardware or software issues, if the data on the disk is important it is imperative that a person takes action to recover the data in any way possible. Sometimes this can be a costly procedure, but in times of crisis, it may be necessary.
