Loss of hard drive space

80G disk, yours is 74G This is normal, the system is An 1024M is counted as a G, and when producing hard disks, it is An 1000M is counted as a G, so it is a lot less on the computer.

Your E disk is missing 5 Gs are gone, you format E and try it, which 5G may come back.

Right-click, Properties, Tools, Start Check. Choose both. Try it.

The files you installed in it have been removed, but there are still a lot of system files on the hard drive, so you can quickly format the hard drive.

There is also a possibility that the hard drive track is damaged, and the bad track is skipped automatically, so the hard drive space is reduced.

It's all like this, there are some system programs and hard disk programs that take up space, and the hard disk labels are inaccurate.

No, I've looked at every partition, even the hidden ones, but I can't find out what these spaces are occupied by or lost. This wasn't the case before, but it was recently discovered that the six partitions together were missing more than 7 gigabytes. :i10

The hard disk will not lose space inexplicably, 80g is calculated, and it is normal to have a few fewer g, because of the difference in conversion. The system is in accordance with 1024, while the hard disk manufacturer is 1000So it's a little different.

7G less, I think there are a few G that have done the hidden partition. This is the case with a lot of system recovery software. It doesn't really matter.

If you want to restore it all, then go into the system and back up your data to your mobile device. Then use the installed version, delete all partitions, repartition, and make the system. And then it's normal.

Don't be surprised, hehe, it's not a big deal.

What does hard disk space have to do with defragmentation and the system? You right-click on the desktop and select [My Computer], select [Manage], and click [Disk Management] at the bottom left to see the situation of each partition. Also, the actual usable space of the 80G hard disk is only more than 70G, because the calculation standards are different, one is 1G, and the other is 1024M.

If all your drives are removed, you can format the drives, and your capacity problems should be solved. Go to your "My Computer" and right-click, click "Manage", click "Disk Management" and your hard drive capacity will appear. It should be about the same as you calculated.

The hard disk manufacturer is 1000M=1G; And the operating system is 1024M=1G. This will result in a discrepancy in the labeling of the capacity.

The missing 5G is occupied by system garbage. Moving things away doesn't mean everything doesn't exist anymore. If you don't have anything on your e-drive, just format it.

Then the "lost" space will be returned. Generally, hard disks are divided into only 4 zones. Every time I divide an extra area, the partition file will take up part of the space, and my disk is only 74G.

But it's all normal. It's impossible to buy an 80g plate, you have 80g of space to use.

Remove everything and format it again.
