Article posted by: aimer kia
CD-ROMs and DVD ROMs seem so permanent; yet if you have ever made CD- ROMs you know that sometimes you can mistakenly make a whole set of drink coasters without knowing why. Now days about every computer have a CD writer as standard equipment. We can store 600+ MB worth of data on CD-ROMs, and 5+ GB of data on a DVD ROMs and this a common practice for many users.
This technical article will discuss CD-ROM / DVD ROMs, some common data loss scenarios and Wonder share recovery efforts.
Complexity Levels
As compared to the other computer hardware, the CD-ROM/DVDâ€"ROM storage medium is a unique and a complex technology. It is easy to take for granted the manufactured CD-ROM that hold our data or music, or the DVDs, of movies that we buy is a result of research and testing work beneath the shiny surface of the disk.
There are few levels of complexity in CD-ROM/ DVD- ROM. First level is with the physical disk itself, the next level is the physical blocks, and with the file system level this provides fundamental structure to the written data. For other storage media there is a file system that maps out where the data will be written. But there is few file system which is designed to handle the data on CD-ROMs/ DVD-ROMs.
Data or music on the CD-ROM / DVD- ROMs there is low level of correction and decoding schemes. This by design to preserve data quality and integrity
Data loss Scenarios
The storage media of CD- ROM / DVD ROMs is easily susceptible to physical damage along with file system corruption. The difference between media damage and media corruption is, media damage is when there is physical wrong with CD ROM or DVD ROM itself. It includes scratches on the writable side of the disk or warping in the disk, holes in the disk which damaged the disk on both the sides. In cases like these data recovery is very difficult. One other situation is media corruption in this situation the dye used in CDR/ Ws or the pits on the CD-ROM / DVD ROM become incapable of representing the binary bits.
The whole file system can be corrupted due to variety of reasons. Everything from software bugs to hardware issues can produce corrupted CD-ROM/ DVD- ROMs.
Manufactured disks go through a strict quality control so this unlikely to find a corrupt or damaged disk. Personal computer CD burners and 3rd party software can corrupt the file system of the CD-ROM/ DVDâ€"ROM.
