禁用坏磁盘垃圾邮件 dmesg/journalctl

是否可以使用命令行禁用磁盘？我收到这样的垃圾邮件：

由于我仍在使用电脑，所以没有重新启动。它让一切都有点滞后。

代码片段中的最后一行dmesg表明写入操作失败。

你可以试试：

echo 1 | sudo tee /sys/block/sdd/device/delete

由于写缓存，将数据发送到磁盘的应用程序已经“承诺”数据与写入一样好，并且内核绝对会尽力遵守这个承诺。因此，只要磁盘看起来可用，内核就会继续尝试写入数据。该命令告诉内核准备磁盘以进行热拔出。如果它有效，/dev/sdd将会消失，并且内核可能会尝试使磁盘旋转（如果可能）。

（如果有人知道如何明确地告诉 Linux 内核“我命令你丢失所有缓存的写操作到此磁盘”，请随意写下您自己的答案或将其编辑到此磁盘中。）
