(虽然我在玩火,但请向菜鸟提供建议......谢谢)
接着,
尝试对 2TB 损坏的 HDD 进行低级格式化,以便它可以使用 SMART 自我标记坏扇区/块。
但是从这个命令得到了这个输出:
sudo hdparm --user-master u --security-erase llformat /dev/sdc
security_password="llformat"
/dev/sdc:
Issuing SECURITY_ERASE command, password="llformat", user=user
ERASE_PREPARE: Invalid argument
我已成功启用安全性。以下是输出hdparm -I /dev/sdc

答案1
好吧,我现在可能承认失败了,但我对未来的用户有答案。
在我的情况下,驱动器连接到 SATA-USB 电缆(12 英镑的 ebay 商品)。显然,其中一些甚至外部驱动器支架都不会将完整的 ATA 命令传递给驱动器。hdparm 的作者 Mark Lord 给我写了两行说明该怎么做,第一行是:
该驱动器应直接连接到主板的内部 SATA 控制器
hdparm 为 Linux SATA/PATA/SAS“libata”子系统和较旧的 IDE 驱动程序子系统支持的各种内核接口提供了命令行接口。 许多 较新的(2008 年及以后)USB 驱动器外壳现在也支持“SAT”(SCSI-ATA 命令转换),因此也可以与 hdparm 一起使用。
去引用Linux 杂志:
Hdparm 接受任何连接到 (E)IDE、SATA 或 SAS 接口的设备作为大容量存储,因此包括 DVD 驱动器和 SSD。USB 转 IDE 适配器经常会导致问题,因为它们不会将 (完整的) ATA 或 ATAPI 命令传输到驱动器。hdparm 提供的信息取决于设备。
我使用的是小型上网本,因此无法通过带状线直接连接到主板,也无法访问其他机器。太沮丧了!
