Contiguous: Immediately adjacent. For example, contiguous sectors on a disk are sectors that come one after the other. Frequently, a file stored on disk can become fragmented, which means that it is stored on non-contiguous sectors. taken from http://www.webopedia.com/TERM/C/contiguous.HTML So one could assume that the difference is that contiguous files are files that are stored immediately adjacent from one another (together) and non-contiguous files are not stored adjacently hence are separated or scattered. Hope this was of some help.
i dont know what it means so please help me ot here.
A sector is the lowest allocation unit in hard disk drives. It can make up into clusters which can be as small as 2 sectors or as much as 4 sectors. Of course this is by no means a conclusive definition of a cluster as disk sizes grow exponentially and newer filesystems are developed to accomodate.
track mean a path in secondary storage, storage contains traks in circles and in every track there is sectors means tracks are dividing in different chunks of sectors
Yes, typically a hard drive has 0 bad sectors. Once a drive starts to develop bad sectors it typically means that the drive is failing. If you don't want to replace the drive right now, you should back up your drive and keep the backup current.
A group of sectors is called a block.
