| 1 | JohnMcPherson | 1 | !! Backing up/Restoring a disk image from/to floppy disk |
| 2 | |||
| 3 | AristotlePagaltzis | 3 | The dd(1) command in Linux is used to do direct dumps from one device (or file) to another. It is an excellent tool to create a disk image or to make a diskette from an image file (*.img). The command is invoked as follows: |
| 1 | JohnMcPherson | 4 | |
| 3 | AristotlePagaltzis | 5 | # dd if=imagefile of=/dev/fd0 bs=72k |
| 6 | 20+0 records in | ||
| 7 | 20+0 records out | ||
| 1 | JohnMcPherson | 8 | |
| 3 | AristotlePagaltzis | 9 | The records counts are dd(1)'s output to indicate how much was read and how much was written. In this example, a full 1.44MB floppy was written (20 * 72k). If you get a smaller block count, the image did not transfer correctly. If this is the case, it will usually be accompanied by a disk error. |
