Hard disk drives are the most important storage devices that store and retrieve data as per users’ needs. Unlike other storage mediums, such as CDs/DVDs, etc., the HDDs consist of ‘Platters’. The platters are coated with magnetic material and magnetic heads are needed to read and write data on them. Platters are logically divided into smaller units called ‘Sectors’. It is the sectors in which the data is stored. The size of one sector is 512 Bytes.
In case of accidental shutdown of the computers (i.e. if proper shutdown method is not performed), sectors of the rotating platters may get corrupt because of the scratches due to the friction caused between the heads and the platters. This causes the data stored in the affected sectors unreadable and/or un-writable.
Sometimes errors can also be caused due to corrupt software applications. Irrespective the cause of error, the error is referred to as Disk Error. When the error is due to any software, it can be scanned and fixed easily. On the other hand, at hardware level, the physical damage can be scanned and detected but cannot be rectified whatsoever. In such situations, the hard disk drives must be replaced immediately to protect data from any loss.
Disk Error Checking
Hard disk error checking is a process in which Windows scans the HDD for errors (like directory errors, cross-linked files, lost clusters and/or bad sectors). The process often contains tools to fix the errors, but if the process scans the disk and detects the error that cannot be rectified, the hard disk must be replaced.
