hdparm 使用正确的密码编码解锁 ssd

我有一个旧的受密码保护的 SSD 通过 USB 连接到我的 Linux 系统。我尝试使用hdparm。

问题是我的密码是./perspective（现在不重要了，因为我只将它用于 SSD，而没有用于其他地方），我认为由于特殊字符./及其错误的编码，我现在无法使用

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

根据这个帖子我必须使用“十六进制扫描码”来识别特殊字符。所以我尝试了

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

/dev/sdc:

PS：请不要标记为重复这个问题因为我最感兴趣的是找到正确的密码编码，但答案中没有与我的设备匹配的主密码。

答案1

尝试hdparm --user-master m --security-unlock NULL /dev/something

背景故事：我有一台 SX900，固件版本也是 5.0.7a。使用 ADATA Toolbox 安全擦除驱动器并重新启动后，我被告知驱动器被密码锁定。ADATA 实际上在他们的程序手册中有一章介绍了这种情况，并提供了有用的建议Use a third-party tool to unlock和Unlock Password: ADATA。只是我不知道程序实际上发送了什么，但驱动器不会接受--user-master u --security-unlock ADATA。我几乎放弃了驱动器，直到我一时兴起尝试了一个空白主密码。

我主要回复这个，所以当我再次软砖这个驱动器时，我就能用谷歌搜索我过去的答案了：V
