Wikipedia describes hard disk encryption as a process of encrypting the hard drive of laptops and work stations so that information is securely stored. This method can also be done on flash drives.
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.

An encrypted hard disk is a disk that has been coded in order for it not to be burned.
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.

Store encryption keys that can be used to encrypt and decrypt secondary storage areas like the hard disk
HDI - Head to Disk Interference.
A trusted platform module (TPM) is a chip that handles FDE (full-disk encryption) and other encryption-based security on a computer. It is primarily used in operating systems such as Windows 7 and 8 with the advent of BitLocker, which if enabled will disallow you from using the hard disk in another computer.
· Compression allows a user to compress files and folders and increase available storage on a hard disk. Encryption makes sure that your documents stay confidential. They are mutually exclusive. You cannot encrypt a compressed file and vice versa.
If you mean full Hard disk encryption, right down to the FAT Table, then I would recommend using a third party program that supports such functions such as "Truecrypt". NTFS for example supports file encryption and windows has "Bitlocker" which supports a type of drive encryption and file container encryption. There are also hardware based methods which allows for OS transparent hard drive encryption that would prevent the drive from being read in another system without the hardware key. File system is USUALLY not important. Since encryption at a hardware level bypasses the OS and is transparent to it.
A computer hard disk or hard drive (fixed disk) is hardware.
