Check Partition and Fix Errors with AOMEI Partition Assistant

Overview of Check Errors on a Partition

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 knoew it by searching on the internet. It indicated a bad spot on a hard drive or within a file if it is seen during a file backup process.

In such a case, it is a good thing to check the disk for error and fix it. Otherwise, something worser would happen. As is also for the student, before he got to know the exact meaning of the message, every time he started his computer, even in safe mode, more data was lost to the point where he was almost unable to start it at all the last time. Had he checked his disks before backup, the disaster would not happen. For his situation, there might be some viruses on his disk and the viruses were also backed up during his operation.

In a word, 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.)
