Line 7: ==Hard Disk Drive FDE== HDD FDE is available from all HDD vendors using the OPAL and Enterprise standards via the [[Trusted Computing Group]].<ref>[https://www.trustedcomputinggroup.org/ Trusted Computing Group: Home<!-- Bot generated title -->]</ref> [[Key management]] takes place within the ~~HDD~~hard disk controller and encryption keys are ~~encrypted using the a cryptologically strong passcode of up to 32~~256 [[~~Byte~~Binary digit\|~~bytes~~bit]] ~~(256~~ [[~~Binary~~Advanced ~~digit\|bits~~Encryption Standard]]) keys. [[Authentication]] on power up of the drive must still take place within the [[CPU]] via either a [[software]] [[Pre-Boot Authentication]] Environment or with a [[BIOS]] password. [[Hitachi]], [[Seagate]], [[Samsung]], [[Toshiba]], [[Western Digital]] are the disk drive manufacturers offering [[Trusted Computing Group\|TCG]] OPAL [[Serial ATA \|SATA]] drives as well as the older, and less secure, [[Parallel ATA\|PATA]] Security command standard. All drive makers have suggested the appropriate term for this new class of device and new type of functionality be "self-encrypting drives."
