Why is there less hard drive space after cutting?

This is a shrinkage of the hard disk, which is normal.

The definition of hard disk capacity by the hard disk manufacturer and the algorithm of the system for the capacity of the hard disk are different, so it leads to the error of the identification capacity and the actual capacity of the hard disk

Hard disk manufacturers' standards: 1GB = 1,000MB, 1MB = 1,000KB, 1KB = 1,000bytes

The algorithm of the operating system: 1GB = 1,024MB, 1MB = 1,024KB, 1KB = 1,024byte

A 40GB hard drive is used as an example to calculate as follows:

HDD manufacturer: 40GB = 40,000MB = 40,000,000KB = 40,000,000,000byte

40GB = 40,960MB = 41,943,040KB = 42,949,672,960bytes

So the capacity of a 40G hard disk in the system is 40,000,000,000 42,949,672,960=

Moreover, after partitioning and formatting, the partition table of the system will also use a certain amount of space on the hard disk, so it will be displayed by the system.

The capacity of the hard disk is always different from the model capacity of the hard disk. This is a normal phenomenon and is basically present on all hard drives.

Are you sure you've cut to the D drive, and if the D drive has the same thing.

How do you see the remaining space, you refresh the list and see.

What file did you cut? If it is a temporary file of the system, it may need to be restarted before it can take effect, so you can try it after restarting.

Point hard drive attributes. Click Disk Cleanup.

There are too many fragments, organize the hard disk, you can open my computer - Tools - View, click out the hidden protected operating system files, display all files and folders, see how many fragments you have, but don't delete them randomly, the system is dead, you have to reinstall.

This is a very common problem, and his storage space is in the format of FAT32.

Because there are 2 hidden files in the C disk of the system, one file and the other are files in the virtual memory set by the system on the hard disk, which cannot be deleted, but the size can be set. When the system is hibernating, all the information in memory is saved to this file, and its size is always the same as the size of your physical memory.

Because the system recognizes 1024MB as 1GB, but when the hard drive leaves the factory, it is 1000MB for 1GB, and the file system is added, so there are only so many of them.

My 160g is actually 149How many gigabytes, I wonder why it doesn't just say it's 150g.

The bigger the drive, the less it is.

Relationship conversion. Hard drive factory specifications.

1000bit=1kb

1000kb =1mb

1000mb =1gb

1000gb =1tb

System Standard Specifications.

1024t=1kb

1024 =1mb

1024 =1gb

1024 =1tb

Do the math of how much you've lost in this way.

It's a matter of setting up virtual memory, but it's not as big as you said.

Generally, after reinstalling the system, the virtual memory of the C drive is changed to the D, E, and F drives.

If you have a new system, you can right-click "My Computer" - "Properties" - "Advanced" - Performance Settings - Advanced "- Virtual Memory Change" to reset the settings, usually set to a multiple of the memory module.

You right-click on the D disk to select the attributes, how many g are used, there is a pie chart display, look at the use of hard disk space is not only to see the file capacity, but also the system cache, page files, ** station allocation space, and the temporary files generated after the program runs, which will also take up a lot of hard disk space!

It's not a big problem to lose more than a dozen g, and there are no other aspects of failure to use first.

If there is a problem in the future, find a portable hard drive to transfer the data in your hard drive. It is best to repartition your hard drive to format it.

I also asked for help, my hard drive has a primary partition that can't be used, I tried to delete the volume label, and now I can't find that disk? I don't know what to do, I wasted dozens of g of capacity.

Are there any other virtual occupancy?

For example, virtual machines and the like.

Do you mean that your stuff is all over the place, or if it's not clear, the space is less than a few tens of g

This has a lot to do with your cache, if you use your computer for a long time, or open some programs, it will call the cache, and the cache takes up space.

It should be the ** station file in the disk,Select the disk right-click attribute and go into the disk to clean up,Delete the ** station file OK。

Your hard drive data has been tampered with, your hard drive is 1m = 900kb, normal is 1m = 1024kb. In other words, the capacity is not that large.

Maybe there's disk fragmentation, try disk cleanup, or defragmentation.

Do you have system backup and restore software such as One-Click Restore Maxdos installed?

Have you set up virtual memory on the D drive?

Yes, the partitioning method is different, you can say fat32 to NTFS format.

Clean up the disk fragmentation and organize the space

There is no imaginary memory set on the D disk.

There must be a hidden document.

I'm sorry that I got you on a mission.

In the folder options, uncheck the box to hide system files, select Show hidden files, and see what files are hidden.

The DG software will not change the size of the hard disk in any way, it is recommended to see the above figure for specific analysis.

Don't be afraid. The source file will be deleted only if the move is successful. What is gone is gone. There won't be a situation where you delete the source file after only half of the file has been moved, unless you forcibly unplug the external hard drive instead of using the "safe removal" method.

It's normal. That's how cutting a file is. Every time a file is pasted, the source file of that file is deleted. What more could you want?

Because the system will not check whether the free space is sufficient first when cutting multiple files, if a file is suddenly said to be insufficient in the middle of the transfer, and the operations at this time are carried out in memory, the files on the hard disk will disappear.

For example, you can use EasyRecovery to scan and recover it.

First, the specific operation method:

2.Open the software and scan the portable hard drive with the advanced recovery features inside.

3.When the scan is complete, review the recovered files and find the cut lost files.

2. Precautions for transferring computer data:

When using removable storage to flip data, be sure not to use the method of cutting.

It should be a copy-paste. After moving the data copy to the destination, confirm that it is correct, and then process the original data.

There are many uncertainties that may cause cutting errors, and there are many times when the cut file cannot be opened on another computer, but the original file has been cut out.

The file that has just been cut to the mobile hard disk is gone, but it can't be seen, but it does occupy the space of the mobile hard disk, and the size of the space occupied is also right, and then the file cut inside can be displayed, and the solution is solved!!

is hidden. Open My Computer, Tools, Folder Options, View, and uncheck the previous check to hide protected OS files. Then click on the display of all files and folders below, and make sure you can see it when you come back.

You can try this method: right-click on the mobile hard disk > > > > > > > > > > > > > > > > > > >

When you're done, open Tools > Folder Options > View, remove the Hide Protected OS Files (Recommended) checkmark in front of it, and select Show Hidden Files, Folders, and Drives.

You will find a hidden file in the portable hard drive, which contains the disappeared file, but it may not be available.

With this software: EasyRecovery Professional can generally get back lost files.
