Help to restore a dd image file back to the hard drive

[ugopher]

I have followed this topic and I was wondering the following: If I already have a dd image split into 640M chunks and want to restore the image onto a new destination drive, 1) Do I need to format my new destination disk as NTFS before I reasseble the image onto my destination drive? 2)Also, Is there an additional command that must be used to tell Knoppix to reassemble the chucks of dd.img.000, dd.img.001..... while it is writing to the destination disk?

no formating needed, you can use the comand cat to put the pieces together again.
like this lets say you have the files::: file1.img file2.img...file9.img you can merge them with the comand

cat file?.img >>whole.img

this will take them in order from 1-->9 and put then as one, but as you have them on different CDS we must go a different route.
so let us say you have image1 on a mounted CD and want it on /dev/hda you do

cat /mnt/cdrom/image1.img>>/dev/hda

next you unmount the cd and put cd 2 in

cat /mnt/cdrom/image2.img>>/dev/hda

... ... ...

cat /mnt/cdrom/image9.img>>/dev/hda

the >> tells cat to continue with the new stuff just where the old ended.
let us hope it works, sometimes it may error out. if so ask and i will try to fins another way, yes there are other ways, SEVERAL other ways.
