我有一个旧密码保护的SSD通过USB连接到我的Linux系统。 我试图用hdparm解锁它。
问题是我的密码是./perspective （现在没关系，因为我只用它的SSD和其他地方），我想因为特殊字符./和他们错误的编码，我现在不能解锁的驱动器
hdparm --user-master u --security-unlock ./perspective /dev/sdc ........................................ security_password: "./perspective" /dev/sdc: Issuing SECURITY_UNLOCK command, password="./perspective", user=user SECURITY_UNLOCK: Input/output error
根据这个职位，我必须使用“hex扫描代码”的特殊字符。 所以我试了
hdparm --user-master u --security-unlock $(printf '\x34\x35\x19\x12\x13\x1F\x19\x12\x2E\x14\x17\x2F\x12') /dev/sdc ........................................ security_password: "45 ./" /dev/sdc: Issuing SECURITY_UNLOCK command, password="45 ./", user=user SECURITY_UNLOCK: Input/output error
hdparm -I /dev/sdc给我

PS：请不要标记为与这个问题重复，因为我主要是在find我的密码正确的编码感兴趣，并没有匹配我的设备匹配的主密码。
