WhyLiveCD is a real magic? Why is it essential?Eversince personal computers started invading our homes back in theeighties of the previous century, it was essential to make backupdata in order to keep vital stored information safe and re-accessiblein future. Hard disk crashes, reinstallations and upgrades ofoperating systems, faulty drivers, faulty hardware, virus infectionsand dozens of more concerns plagued administrators of that time andusers alike. Not much changed in recent times, only now regularpeople know that there are ways how to restore the system on apersonal computer and save some of the data that has been storedthere.DatarecoveryBesidesthe already mentioned data recovery possibility, namely to restorefrom a backup, there used to be and there are many possibilities howto recover and save data on a faulty system. Some of such utilitieshave found ways even into the current operating systems and some wereand are available for purchase as commercially sold products. But themost interesting software for such purposes was undoubtedly what hasbeen dubbed as forensic recovery software, when it first cameout. Mossad,CIA, KGB and the likesBootingup a computer that had sensitive data on it and was recovered duringan agency or police actioncan be tricky business. If some terrorist or crime lord has acomputer, that computer is guarded by more people than the personitself. It is therefore expected that such highly classified datawill be software protected and possibly auto-erase if accessed byunauthorized hands. For such reasons certain programs have beendeveloped that simulated a complete operating system, giving theforensic computer expert the chance to access data on such a harddrive, which was removed from the original machine, and try andrecover some if not all data on the disk. In such environments it ismuch easier to run decryption programs and also review unencrypteddata that might give more insight to the investigating office.Thisforensic software was located on such a bootable disc and built inoperating system can be bypassed in a fast intrusion action allowingthe specialist to access available data in quick succession. Applicationsfor the common manThisbootable OS idea has been picked up by data recovery specialists andthen by computer software makers, who decided it is a good idea toallow the end user to access files that are otherwise inaccessible byfaulty, damaged or destroyed operating system. This is what a Live CDactually is. A full operating system that is bootable from a CD (orDVD Live DVD, or USB drive Live USB) and that can be used tonot only save data, but to have a portable operating system. Whatcan it be used for?Besidesthe aforementioned forensic capability, Live CDs are commonly usedfor virus removal purposes. The other use is for salvaging faultyand broken operating systems, also called system recovery. Salvagingdata and copying drives is another use, but also salvaging andrecovering hard disks. The reason is simple: People like to repairtheir own machines by themselves and doing it in an environment thatis similar to the operating system they are running is just going tomake the users more computer savvy and knowledgeable.
