When checkdisk detects a bad cluster on your hard drive, it automatically flags the cluster as unusable and your file system will no longer put data there. This is as close as you can get to actually fixing the bad clusters. Bad clusters are caused by physical damage or defects on the disk itself. When modern hard disks start showing bad clusters, it should be taken as a sign that the hard disk is dying and should be replaced.
Scandisk is a utility program that checks and repairs file system errors on a computer's hard drive. It scans the disk's file structure, looking for errors such as bad sectors, lost clusters, and cross-linked files.
It's pretty rare these days, due to the advances in the stages of manufacture for the hard-drive. Bad clusters - are areas of damage on a computers hard-drive. during a diagnostic scan, it's possible to 'mark' these bad clusters, so that the computer bypasses them when it needs to write information onto the disk.
A bad cluster is a hard disk cluster which has been flagged by the file system as being corrupted or damaged in some way, and thus will no longer be used for storing data. In the olden days, it was not uncommon for a new hard disk to have a few bad clusters on it here & there due to minor manufacturing flaws and perhaps develop a few more during its normal lifespan. However, in modern parlance a bad cluster is almost always followed by several more bad clusters, and is a sign that the hard disk will soon fail completely.

bad
Probably a bad (scratched) disk. If it happens with every disk, then it's a bad disk drive.

To Fix the PC hangs (computer hang problem),you need to follow two steps:Step1: Check that the cooling fans on the processor is working properly or not. So ensure that the fan is working fine and is clean. If not, then get the fan replaced. Also check for the additional fans on your computer casing/cabinet(if any).Step2: To Fix this, run a disk scan which checks for disc errors and fixes the bad sectors (some examples are scandisk and checkdisk utilities in windows). If there are bad sectors which can not be repaired, then you need to replace your hard disc.
