如何验证磁盘是否是新的并且出厂时没有写入？我有一个客户需要确保他恢复的磁盘是干净的并且从出厂到他拥有期间没有被篡改过。我拆开了一台服务器的包装（上面没有操作系统，磁盘上没有分区），这就是我看到的

制作驱动器时会进行测试吗？如何验证我收到的磁盘是否干净且写入了 0 个字节？我理解我可以使用 Scrub（如此处所述）https://linoxide.com/linux-command/commands-wipe-disk-linux/)，但如果不需要的话，我宁愿不让它磨损。

你需要指挥hdparm 开关/选项大写“i”或“I”将为您提供所需的所有信息。有一个信息提供总旋转时间。
$ sudo hdparm -I /dev/sda
