Check Partition and Fix Errors with the Help of AOMEI Partition Assistant

June 26, 2017

For a formatted partition, partition checking can discover some errors of the file system to ensure the integrity of your data files. And on a disk or any partition, the function will scan each disk sector status by reading data from the sector.
How to Check Partition and Fix Errors?
There is a grad school student in the middle of an important project with a deadline, and as is usually the case, his computer crashed at the worst possible time. He tried desperately to back up his data and save his hard disk, but he kept getting “cyclic redundancy” message without knowing what it is. Later, he knows it by searching on the internet. It indicates a bad spot on a hard drive or within a file if it is seen during a file backup process. In such case, it is a good thing to check the disk for error and fix it. Otherwise, something much worse will happen. As is also for the student, before he gets to know the exact meaning of the message, every time he started his computer, even in safe mode, more data was being lost to the point where he was almost unable to start it at all the last time. Had he check his disks before backup, the disaster would not happen to him. For his situation, there may be some viruses in his disk and the viruses were also backed up during his operation.
It is important to check error before other partition management operations
In order to perform disk operation such as resize partition, split partition or merge partition safely and successfully, you are required to check that partition beforehand. The major function of Check Partition is to find errors in file system to ensure the integrity of your data. If the program finds errors on a partition during checking process, the file system might be damaged and consequently, you are unable to execute resize/split/merge operation on that partition smoothly. With the help of partition checking function, you could find the errors in time and then find a remedy. (Tips: AOMEI Partition Assistant provides not only feature to find errors but also service to fix it.)
Before you do
This feature can be used only on a formatted partition.
Make sure there is no extra application in use before you check partition because that application might be accidentally closed if AOMEI Partition Assistant perceived it. Also, for best results, don't use your computer for any other tasks while it is checking for errors.
Tips: This operation can check your partition with its content intact.
To check partition
Of course, you need to download, install and launch AOMEI Partition Assistant before starting.
Step1. Right-click on the partition which you are going to check and choose Advanced -> Check Partition.
Check Partition
Step2. Select the way of checking errors to perform. There are 3 options:
Check partition and fix errors in this partition by using chkdsk.exe
Check partition for errors by using chkdsk.exe
Check whether there is bad sector on the partition
The first option not only finds out the wrong parts in the partition but also deals with them; the second choice only gets the errors while the last one just tell you whether there is bad sector on the partition. From the first one to the very last, the requirements level lows down, so the time they cost decrease. In this case we choose the default (the second option). After that, click OK to continue.
Checking Methods
Step3. The operation will be completed successfully in a few seconds or minutes. While it is operating, you can view how far it goes through the processing bar on the pop-out window. Click OK to finish this task.

To check and fix partition
If you not only want to check a partition but also want to fix it if there is any error in the partition, then you need to study the following steps carefully the things you have to do is a little different from that above.
The steps of fixing partition are roughly the same as check partition. However, the step 2 is slightly different. When you head to Step 2, choose Check partition and fix errors in this partition by using chkdsk.exe. The rest of the steps are the same as those mentioned above.
Check and Fix Partition
You can use chkdsk.exe to check the partition that has a drive letter only. For the partition without drive letters, namely, the unallocated space, it should be labeled before you can check it.
Depending on the size of your drive, this might take several minutes.
As for Check whether there is bad sector on the partition, the operation steps are also similar to those two involved above. The little differences are that you should choose Check whether there is bad sector on the partition in the second step and when you click OK, a window will pop out to confirm the decision you have made. At this moment, you just need to press Start button to begin the operation. It will show you how is it going and many details such as where the bad sectors located and the time it has already cost. This option is the fastest one of the three. However, you can do it much faster by ticking Quick Check in the pop-out window.
