From startup computer programs that make it work are read and rewritten on the hard disk again and again, and this in itself carries a risk, because to fail any read / write operation due to software errors or users, move the machine while the hard drive is active, a bad shutdown or a power failure, to name just a few examples, it can cause damage to the system that may require reformatting the hard disk. The risk increases when you install or uninstall applications, and reaches its maximum when entering the Internet as there are always "witches" that we provide the latest model of virus.
Windows uses by default only the C drive for the operating system and all personal files and folders from users, all in one unit. If the hard disk needs to be formatted folders and personal files will be obligatorily deleted.
From the earliest days of computing there are many applications designed to image the disk to retrieve all lost, apart from the implemented system utilities for Microsoft Windows itself. The disk image can rebuild what was lost and leave as it was the same disk, and must regularly update as often as possible, because any unsaved changes will be irretrievably lost.
No disk image can be used to create an alternative C drive on the same computer. If we want to have him follow a different procedure, and this is the purpose of this tutorial. We assume that Windows leaves the possibility of creating up to three primary partitions that can act as a hard C, and devote the remaining space to logical drives completely independent of the operating system and are a much better place for user files such as movies, music photos, letters etc, which then appear in File Manager with the following letters (D, E, F, G ...) and divide it using the disk as follows:
- Primary Partition 1 with an insignificant size of only 100 MB for the boot manager, hidden and always acting as active unit, handles for either of the other two and allows the user to choose to boot either as disk C .
- Primary Partition 2, size 25 GB, is used to install Windows 7 it is the C drive by default.
- Primary Partition 3, size 25 GB, a copy of the earlier obtained in a quick and easy, is the C drive alternative.
- Logical Drives: as many as you like with the size you want, to fill the hard disk.
The main advantages of having doubled the operating system are many, most notably including:
- The C drive can be formatted and rebuilt at any time without affecting either the master boot record (MBR) or boot sector of the partition (PBR), or of course the user files.
- The primary partition does not appear as drive C (in the File Manager is a letter following the logical units dedicated to personal files and folders), properly treated in the manner described, allows to create backup copies either by direct copy or a compressed file. The course deals direct copy more than 4GB, but the compressed file fits on a single DVD.
- You can rebuild the damaged unit while working with him just a quick format on it and return a copy (it takes about 10 minutes in the background.)
- The division of the hard disk into multiple parts means less fragmentation, more stability and more speed work.
