- An ISO file is an image of a disk whether CD or DVD. The purpose is to create a backup that can then be burned onto another disk for use. It can be considered a master copy, the raw data on a disk: files, folders, formats or anything else. If you're familiar with a .zip or .cab file, it's much the same without using the compression.
- ISO files can be made by using the proper software for the job. Most CD/DVD burning software includes an option to create an ISO image like NERO Burning ROM and ImgBurn. These are often free to download. Be aware that not all disks will allow an image to be created because they are copy protected. This is to prevent piracy, but causes frustration as legal copies for personal use can't be made to preserve the original as a master in case something were to happen to it.
- Burning an ISO file is normally easy. However, there are instances where ISO errors will occur during the burning process. One of these is called Cyclic Redundancy Check (CRC).
CRC is the method of error checking to make sure the data that was read is what is written. This is done mathematically, and when the numbers don't add up, an error occurs. This is the most common cause for all ISO errors. - One of the most common reasons for an ISO error is bad media. The disk may be scratched, smudged or dirty. Using an off-brand media can potentially cost more money in the long run by stacking up unusable media from erroneous burning attempts.
If using Windows, checking Microsoft's Hardware Compatibility List (HCL) for the version being used can insure that the drive will operate effectively. - A wide array of issues can cause an ISO error. It could be that the device had a bad writing process and simply re-burning will solve the issue. The writer itself may have dirt or debris in the writer or reader. The drive could be on its last legs and ready to be replaced. Last, the drive itself may be out of alignment by being slightly off-center or tilted in some way.
