This article mainly explains the "Linux system light drive soft switch and speed limit is how many", the article explains the content is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in depth, together to study and learn "Linux system optical drive soft switch and speed limit is how much" it!

First, the soft switch of the optical drive:

Eject-r cdrom, pop open the door of the specified optical drive device. If there is only one optical drive, you can directly use eject. If there are two optical drive devices, specify the device according to the device file under / dev/. For example, there is a COMBO CDROM on my machine, and the device file is / dev/cdrom1. Use eject-r cdrom1 to execute.

Close the barn door with the-t parameter, if you close my COMBO, use the following command: eject-t-r cdrom1. And another advantage of having eject is that it can automatically mount the optical drive to the file system and automatically remove the file system when it pops up.

Second, the speed limit of optical drive:

Eject-x n cdrom,n is the maximum double speed. In practical use, n should be greater than or equal to 4, and there is no limit to the upper limit.

Eject also comes with a small software volname, which is used to read the name of the CD. Usage: volname / dev/cdrom. If your Linux does not have X-Windows, you can easily know the volume of the CD in TEXT mode.

Hint: the problem of Chinese character file name. If you use eject to hang the optical drive file system, if there are Chinese characters on the CD, the file name will be "?". After looking at the source code of eject, it is found that the file system is set up by calling the settings in the file / etc / fstab. As long as you add iocharset=gb2312,codepage=936 to the penultimate column of the line / dev/cdrom, and re-use eject to connect the CD, you will find that the Chinese character file name can be displayed correctly.

Thank you for your reading, the above is the content of "how much is the light drive soft switch and speed limit under the Linux system". After the study of this article, I believe you have a deeper understanding of the problem of light drive soft switch and speed limit under the Linux system, and the specific use needs to be verified in practice.
