Norton Disk Doctor, ScanDisk, or a similar utility can then be run to verify the integrity of the destination partition. 38 Managing image files Managing image files Norton Ghost can create an image file that contains all the information required to recreate a complete disk or partition. Image files are a useful way to store and reliably compress images of model system configurations, or to create backup copies of complete drives or partitions. The image files created with Norton Ghost have a . gho extension by default. They can contain the entire disk or partitions in the disk. Image files support: s s s s Various levels of compression CRC32 data integrity checking Splitting of media files Spanning across volumes If you also use the Ghost Explorer application, an image file companion utility, individual files from these image files can be recovered selectively without having to restore the complete partition or disk. Image files and compression Image files created in Norton Ghost support several levels of data compression. When using Norton Ghost in interactive mode, three compression options are provided: none, fast, and high. The Norton Ghost command-line switches provide access to nine levels of compression. The compression switch -Z is detailed in Appendix A. As a general rule, the more compression you use, the slower Norton Ghost will operate. However, compression can improve speed when there is a data transfer bottleneck. There is a big difference in speed between high compression and no compression when creating an image file on a local disk. Over a NetBIOS connection, fast compression is often as fast as, or faster than, no compression. Over a parallel cable, high compression is often faster than no compression because fewer bytes need to be sent over the cable. Decompression of high-compressed images is much faster than the original compression. The level of compression you should select depends on your own individual requirements. 39 Chapter 3: Using Norton Ghost Image files and CRC32 Cyclic Redundancy Checking (CRC) is a data error checking technique. CRC ensures that the original data that was written to the image file is the same as the data that is being used from the image file. The 32 value in CRC32 indicates the CRC technique uses a 32-bit value to store error checking information. The use of CRC32 increases detection of errors in the image file. When image files are created, CRC32 details are embedded into the file to ensure image file corruption can be detected when it is being restored to disk. CRC32 is currently included on a file-by-file basis with FAT partitions and on a MFT table basis for NTFS partitions. In addition to image file error detection, the CRC values can be used to verify that image files and partitions or disks are identical.
