That depends on encryption you are using. In any case OS creates partitions and formats it (or specialized software). Next if you have software encryption, than special driver is installed which either encrypted files or whole disk by intercepting read and write operations called by OS. If you have hardware encryption, then your whole hard drive is encrypted on hardware level. It means that hardware has extra steps before writing or reading information on hard drive.
disk By default, 'C' denotes a partition of your hard disk drive (given that it has been partitioned) in which windows and its associated system files are stored. C is known as the Local Disk Drive.
Disk encryption protects the data on a hard drive from being read by someone that isn't authorized. Disk encryption works by converting the information on the drive to unreadable data.
basic disk
It's your internal Hard Drive or the amount of space partitioned for your operating system on that hard drive
Hard drive encryption refers to the coding which is on every computer hard drive. It is the codes that allow the information to be hidden from hackers online.
To fix a computer disk drive you just put some glue on the disk.
Double click on the "My Computer" button (It says "Computer" if using Windows Vista or Windows 7) . Look for the "Local Disk". If more than one Local disk appears, the Hard Drive is partitioned. It should be the sum of all the partitions. For Macintosh users, just go to the "System Profile" option, by clicking the apple on the upper left.
Hard drive, Disk drive and FLoppy disk drive
The disk drive
A disk drive is a device that computers can use to read and write information on computer disk. An example of one is the hard disk drive.
A computer floppy drive is the device that reads and writes to a floppy disk. It is located on the front of the Computer.
If you have an older computer the 3.5" floppy drive fits into the disk drive. Newer computers only have "cup holders" for CD or DVR disks.
