What should I do when the Ubuntu hard disk reads and writes?

Usually, the Ubuntu system hard disk will not make a sound when it is read. If the Ubuntu hard disk reads a very loud sound, it is not necessarily a hardware problem. It can be adjusted by commands to reduce the noise. Let's take a look at it with Xiaobian.

You can use the command hdparm, which can set a lot of parameters related to the hard disk, and the sound of the hard disk can also be used.

The description of the command is as follows:

Usage: hdparm [options] [device] . .

Options:

-a get/set fs readahead

-A get/set the drive look-ahead flag (0/1)

- b get/set bus state (0 == off, 1 == on, 2 == tristate)

-B set Advanced Power Management setting (1-255)

-c get/Set IDE 32-bit IO setting

-C check drive power mode status

-d get/set using_dma flag

-D enable/disable drive defect management

-E set cd/dvd drive speed

-f flush buffer cache for device on exit

-F flush drive write cache

-g display drive geometry< Br>

-h display terse usage information

-H read temperature from drive (Hitachi only)

-i display drive identification

-I detailed/current information Directly from drive

-k get/set keep_settings_over_reset flag (0/1)

-K set drive keep_features_over_reset flag (0/1)

-L set drive Doorlock (0/1) (removable harddisks only)

-M get/set acoustic management (0-254, 128: quiet, 254: fast) “You can set the sound

-m Get/set multiple sector count

Omitted. . .

sudo hdparm -M128 /dev /sda

After setting effects significantly improved, other parameters need to be further studied.

From this point of view, this sound also helps to find the hard disk read and write status, and the hard disk indicator function is almost the same.

The above is the introduction of Ubuntu hard disk read very loud solution, if you read the hard disk after the method of this article is still very loud, then it may be a hardware problem.
