data encryption the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. Historically, data encryption has been used primarily to protect diplomatic and military secrets from foreign governments. It is also now used increasingly by the financial industry to protect money transfers, by merchants to protect credit-card information in electronic commerce, and by corporations to secure sensitive communications of proprietary information.
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.
Encryption is available in the NTFS file system because it supports advanced security features, including file permissions and access control, which are essential for managing encrypted data. NTFS is designed for use in environments requiring high security and data integrity, while FAT32 is a simpler file system that lacks these advanced features. Consequently, FAT32 does not provide the necessary infrastructure to implement encryption effectively.
Sun's Solaris OS supports the ZFS file system natively.
Nothing. The FAT file system simply does not support the features needed for file/folder encryption. You'll have to convert the volume to NTFS.
It becomes readable. Only NTFS supports encryption.
Hi! NTFS file system supports needed options.
No NTFS is the only file system capable of encryption
Convert the volume to NTFS
Convert a FAT volume to NTFS so that you can use encryption.
Encrypting File System (EFS)
Folder encryption is a form of disk encryption where individual files or directories are encrypted by the file system itself. More information can be found at Microsoft.
