我使用磁盘实用程序在 Ubuntu 中启动了安全擦除操作(见下文示例),机器锁定了,我重新启动了它,现在无法再访问磁盘。启动时,BIOS 要求输入磁盘密码,我不知道密码是什么。我试过清空和输入我的 Linux 用户密码,但都不起作用。我想我的希望是磁盘实用程序在擦除过程中使用一些默认密码,并且这里有人知道那是什么。最后要说的是,我发现这个问题它似乎有我需要的答案,但不幸的是,我使用了 Live CD 中的磁盘实用程序,因此没有日志。
我也尝试使用hdparm
上述密码来解锁驱动器。
sudo hdparm -I /dev/sdb

答案1
我误解了另一个答案的意思,我不必查看日志,xxxx
这是字面上的密码。因此只需输入:
sudo hdparm --user-master u --security-disable xxxx /dev/sdb
我刚刚尝试过并且它有效。
希望如果其他人遇到这种情况,它可以提供帮助。
