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 .
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.
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.
Note:
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.
