For a formatted partition, partition checking can discover some errors of the file system to ensure
the integrity of your data and on a disk or any partition, this function will scan each disk sector
status by reading data from the sector.
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 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. 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 recognize it. Also, to get best results, please 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
To Check Partition
Of course, you need to download, install and launch AOMEI
Partition Assistant before starting.
Step 1: Right-click on the partition which you are
going to check and choose "Advanced" -> "Check
Step 2: 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 option gets the errors only while
the final 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 second option by default. After that,
click "OK" to continue.
Step 3: 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 process on the pop-out window. Click "OK" to finish this
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 and the things you have to do are a little different from above. The steps
of fixing partition are roughly the same as "Check Partition".
However, the step 2 is slightly different. When you go 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.
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 process might take several
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 how long the time it has already
taken and this option is the fastest one of the three. However, you can do
it much faster by ticking "Quick Check" in the pop-out
