ata锁定的硬盘, 在windows下没有工具可以解锁,在linux下,可以使用hdparm进行加锁,
用hdparm -I /dev/sda 可以看到 Security 段有提示 locked,
这里可以使用硬盘的master密码进行解锁:
hdparm --user-master m --security-unlock ***** /dev/sda
hdparm --user-master m --security-disable ****** /dev/sda

		ATA Security Commands:
	
		 Most of these are VERY DANGEROUS and can destroy all of your data!
	
		 Due to bugs in older Linux kernels, use of these commands may even
	
		 trigger kernel segfaults or worse.  EXPERIMENT AT YOUR OWN RISK!
	
		 
	
		 --security-freeze           Freeze security settings until reset.
	
		 
	
		 --security-set-pass PASSWD  Lock drive, using password PASSWD:
	
		                                  Use 'NULL' to set empty password.
	
		                                  Drive gets locked if user-passwd is selected.
	
		 --security-prompt-for-password   Prompt user to enter the drive password.
	
		 
	
		 --security-unlock   PASSWD  Unlock drive.
	
		 --security-disable  PASSWD  Disable drive locking.
	
		 --security-erase    PASSWD  Erase a (locked) drive.
	
		 --security-erase-enhanced PASSWD   Enhanced-erase a (locked) drive.

		                                  h   high security (default).
	
		                                  m   maximum security.
