After reinstalling the computer, the computer is only left with the C disk, but the capacity of the

Dizzy,It's very simple,Your current problem is a hard disk without partitioning the system,Of course, there is only one drive letter,You have to reinstall the system once,Before installing the system, you must partition it first,If you don't know how to install it, call someone who will help you,Use a disc or a U disk,Partition first,Then install the system on it,System partition because there is a system running,So you can't split the system partition,Reinstall the system is the only way。

What system are you if it's win7 that's easy to solve,It's very convenient to compress partitions directly into disk management,Specific steps to search on the Internet,If it's xp, you want to repartition,This is very troublesome,You go to the Internet to take a specific look,But be cautious Operation,Otherwise, it will often boot blue screen self-check。

This is due to the fact that you don't have a partition, you can solve the partition problem with the auto-install disc, quickly divide into four zones option, and then press 1 to install the system automatically.

ghost installed?

If it's a ghost installation, you should try to rebuild the partition table first.,Get back the hard disk partition first.。 You can use diskgen to rebuild the partition table and search it interactively. After that, reinstall the system, don't choose the wrong one, or there will be another problem.

Install a partitioning software to partition it, you can, such as "Hard Disk Partitioning Software Magician PQMAGIC".

Repartitioning the C drive 486g means that your hard drive is 500g and it will be fine after dividing the area.

Not seeing the capacity doesn't mean there's something wrong with the drive, and there's no direct relationship between the two.

If you just do a partition operation, you can generate a drive, and the partition will be displayed, and only after the formatting operation can the system recognize the capacity of the partition and display it.

At the same time, if the partition uses a file system that is not supported by the current system, the capacity will not be displayed, so it will not be used as a credential.

However, the possibility of hard drive corruption cannot be ruled out, and formatting can determine whether the hard drive has been damaged.

If your hard disk is not partitioned, this situation may occur,You need to use the partition assistant in PE to partition,C disk capacity 80G is good (refer to Win7 system),After partitioning, you will see C disk。

If it has been partitioned, or you can't see the C drive (and the D disk can't be seen), then there is a new computer mode and an old computer mode when the PE starts, and it should be good for you to change the mode into the PE system.

Be sure to back up your data before reinstalling, I hope it helps you.

If you can't see the capacity of the computer C disk when you reinstall the system, then it is probably because you need to format the system disk to see the capacity again.

When the computer redoes the system, it is not possible to see the size of the C drive, which is normal because the C drive is being formatted and reading data.

For a quick solution, it is recommended to use the PE system disk to boot the computer, enter the partition tool on the desktop, that is, diskgenius, and click the "Quick Partition" button in the window to quickly partition the hard disk and rebuild the MBR at the same time.

After the partition is completed, install the system according to the normal method, and it can be started normally.

It should be noted that fast partitioning will lead to the loss of all data on the hard drive, if you have important files, please back up in advance.

PE may have some drawbacks, it is recommended to use the disk in the installation disk to format the installation system when changing PE to install the system. Only in this way is the most stable format under pure DOS. You can try.

If the C drive is not formatted, it will not be visible.

First, this is due to the different conversion methods of hard disk capacity.

As we all know, binary is used in computers, and in the computer world, it is more convenient and neat to process bytes in batches with the power of 2. 1KB per 1024byte, 1MB per 1024KB, 1GB per 1024MB, 1TB per 1024GB, and TB, GB, MB, KB in the International System of Units are the "decimal system" numbers, for which the International Electrotechnical Association (IEC) has formulated"kib"、“mib”、“gib"binary units, which are used to indicate the data size of "1024 carry"; In terms of computing capacity, hard disk manufacturers use 1000 as a base, 1KB per 1000 bytes, 1MB per 1000KB, 1GB per 1000MB, and 1TB per 1000GB, and the calculation of capacity in the operating system is based on 1024 as the round, and it has not been changed"kib"、“mib”、“gib"binary units, this difference causes the capacity of the hard disk to "shrink".

Hard disks need to be partitioned and formatted, there are differences between operating systems, coupled with the behavior of copying files when installing the operating system, the hard disk will take up more space, so there will be a difference between the hard disk capacity and the nominal capacity displayed in the operating system, and the difference between the two types of hard disk capacity should be about 5%-10%.

Second, the end of the partition is just at the end of the disk or sector, and the partition is based on the sector, which will cause the actual capacity after the partition to be large or small, plus the conversion method is different, and the result is generally more small.

The algorithm of the computer is 1024k=1m, 1024m=1g, and the algorithm of the hard disk manufacturer is 1000k=1m, and 1000m is equal to 1g

Your house has 80 square meters, but the usable area is definitely not 80 square meters, that's the reason, hehe.

That's right. The algorithm of the computer is 1024k=1m, 1024m=1g, and the algorithm of the hard disk manufacturer is 1000k=1m, and 1000m is equal to 1g

After the computer hard disk is partitioned, each partition will automatically generate a part of the system files, which are used to drive the operation of the partition. And the cache part will be set aside.

Why bother with this, it should be an algorithm problem.

2. After the program is opened, directly double-click the physical disk that needs to be recovered, and only the C disk needs to be restored from the physical disk after ghosting.

3. It takes an average of a few minutes to half an hour for the software scan to be completed.

4. The program will quickly put the scanned files into the "Recovered Partition" directory.

5. Tick all the data that needs to be recovered, and then click the Save and "File Save" button in the upper right corner to copy the files on the check.

6. The last step is to wait for the program to copy the file.

Click the Start button, right-click Computer, select Manage (G) from the menu (requires administrator privileges), click Disk Management in the sidebar of the Computer Management window, check for partitions that don't have a drive letter assigned to them, and if so, right-click the partition and click Change Drive Letter and Path (C) in the menuIn the pop-up window, tap "Add (d).."Check Assign the following drive letter (a):

radio box, select a drive letter from the drop-down menu next to it, and tap OK. Finish.

Internet access is slow.

The system sets up a restore point.

Of course, the C drive is getting bigger and bigger.

There is an optimization master Qingqing.

It's normal, you can use 360 to clean up the garbage or 360 to move the C drive.

Of course, the best way to do this is to reinstall the system.

There are a lot of random files in the system, and with the 360 junk file cleaning tool, it's almost the same to clean up.

I'm using QQ PC Manager, so I'll take a screenshot for you.

Dude, a little bit, thanks.

Every time the system is reinstalled, the original is not deleted, but compressed and stored in the C disk, the more times all the systems are reinstalled, the more the computer is stuck.

This depends on what system you reinstalled, if it was originally XP, that XP only occupies about 2G space, and Win7 will take up more space, which will cause the remaining space to become smaller.

Summary. The reason why the computer only has a C disk is that there is no partition, and the reason that there is only 100GB left is that it is occupied by files, please use a disk cleaning tool: common tools such as velvet to clean up garbage and remove the temporary files accumulated by the system.

After the cleanup, can other hard drives appear.

Hello, this is a problem of dividing the disk, after cleaning can not be divided into other disks, only the reinstallation system for the division. We're glad to help you.
