After Windows 7, the storage connected to the PC is subject to automatic defragmentation.In the case of Windows 8.1, the HDD is a mechanism to eliminate basic fragments (fragmentation), and execute the TRIM command in a certain schedule for SSD.However, automatic defragmentation of HDD, which is increasingly large capacity, may interfere with daily work.Therefore, let's introduce how to review the settings regarding "Drive Optimization".
In the structural HDD, if the file is fragmented (the data is scattered in various places without continuous arrangement), the movement time of the head increases.Inevitably, it leads to a decrease in access speed.As a result, it also affects the performance of the entire PC and the response to Windows 8.1, making it a so -called "slow PC".Therefore, Windows 7 has a schedule for performing defragmentation every night.
Windows 7 automatic defragmentation (schedule of disk -default tool).Run every week at midnight |
Windows 8.1 also has a similar configuration dialog, but frequency selection is every day/every week/month.The item to select the execution time has been removed.This is because we are running a task to confirm the fragmentary state, whether or not an automatic defragmentation is needed.
For the automatic defragmentation (optimization of the drive) of Windows 8.1, the item to select the execution time is omitted. |
It can be confirmed that the task execution timing of the task scheduler and the execution timing of the automatic defragmentation are at the same time. |
I couldn't see what conditions were running the task, but the interesting thing is the execution option.When I checked the help from the command line, I said that "the optimization suitable for each media is executed in all volume in the priority" "normal", but the only explanation of "$" is not found (figure below).I checked the operation with the optional "$" removed, but it was not possible to confirm the difference in optimization processing such as the integration of the vacant area.
Contents to be executed in automatic defragmentation tasks.The option "$" that you do not usually see is assigned |
Optional "$" I tried running from the command line, but I could not confirm the difference. |
Automatic defraging that cannot be controlled at the user level, but is important.As shown in the figure above, the automatic defragmentation is defined and "weekly", but if the PC is used low, it may not have to be executed so often.
If you use a PC every day, it may be "every month", except for a case where a large amount of files are operated.For this setting, select "Every month" from the "Drive Optimization" dialog dialog dialog.
Press the "Win"+"R" key, etc., start "Run with the file name", enter "DFRGUI.exe" in the text box, and click/tap the "OK" button. |
When "Drive optimization" starts, click/tap the "Change Settings" button. |
Click/tap the drop -down list, select "Month" from the list, and click/tap the "OK" button. |
With this, you should be less troubled by automatic defragmentation in situations such as opening a 2in1 PC and working.In addition, when a remove media such as an SD card or a USB memory is installed, it is included in the target of the automatic defragmentation.This is the dialog that appears when you press the "Select" button, and uncheck "Automatically optimize a new drive" or check the remove driving manually from the list.
"Automatically optimize a new drive" or click/tap the remove drive in the list to remove the check and tap the "OK" button. |
