floppy with dd and nfs cleint

Postby ccc » Sun Jul 24, 2011 11:02 am

hi

Is it possible and how it works to create just one freesco floppy with dd command and nfs client?
I'd like to make an image of the whole hard disk.

I am not sure what you mean by a nfs client. But the dd command can create a floppy disk very easily. You use a command like
Code: Select all
dd if=./freesco.043  of=/dev/fd0

On some systems rather than using /dev/fd0 it might be /dev/floppy or in some cases /dev/fd1
The file freesco.043 is however just a disk image and can be written to a floppy using any type of disk image software. For Windows machines you might need to add a .img or possibly .ima or even .bif if you want to add it as a boot image file.
If you are afraid that you might make a mistake. The chances are high that you will never learn anything.

Thx, but I'd like to make an image of the whole hard disk using dd and put via nfs over the network (LAN) on the nfs server.

To do what you are asking will require the machine with FREESCO on it to have it's hard drive installed in another Linux machine. Because when using the dd command the drive you are reading should NOT be mounted. Then ust use the dd command in a similar manor as above except the if= (Input File =" will be the device where the drive is located, something like /dev/hdb and the of= (Output File =) is any name you choose. Just be aware that the file will be the same size as the hard drive, so the new machine will need to have a large enough drive in it to hold it. To do what you are asking is easier using something like Norton Ghost booted from a floppy which has network backup capabilities Because the dd command will always generate an exact duplicate of the physical drive. Which means the same sectors and blocks regardless of the actual size of a new hard drive. It also copies marked bad sectors the same as good ones.
