Thanks a lot!
It is good to know that my backup is not corrupted.
I'm very much relieved by this knowledge.

How do you know which byte size to use?

For example I just made an iso of a video using this command

dd if=/dev/hda of=/home/trist007/doug1.iso bs=2048 conv=sync,notrunc

Then I used nero 7 to burn a dvd using that iso and nero informed me that the byte size of 2048 was incorrect. It asked me if I wanted to correct or ignore. I chose to ignore. It burned successfully, but I can't get the video to play. How do I know which byte size to use when I use the dd command for any given medium?

Thanks very useful, this worries me

>Dd is not presently able to clone Microsoft Windows Vista OEM Partitions.

Does this mean only OEM Vista (and Windows 7) partitions? So machines that have been 'upgraded' from Xp should still be ok? Is it what is in the partitions or the whole structure of the disk?

Where'd you get this from? I tried to search through the last few pages of this forum, but to no avail.

Does any body know for sure if this is true, or why it might be?

Where did you hear this or read? What has OEM got to do with the partition? What is an OEM partition? Something special? If you are speaking of a OEM install of M$ Vista then some do make installations across more than one partition. You would then need to address the multiple partitions in use.

I believe you've been had with improper or just plain wrong information. You should 'man dd' to get some information to defend when someone presents you with mis-information.

It's in the first post of this thread by 'Awesome Machine' about half way down at the end of the 'Ms Windows' section.
Perhaps you'd like to tell him he's misinforming people :-)

Hi,

As I stated you have you handle the partitions independently. The 'hidden' must be either quashed or moved.

If this 'reply' is in response to my quote it makes about as much sense as AwesomeMachine's original comment on Vista, sorry.

Please explain more, I'm familiar with the MBR and partition structure of a normal HD

As of Vista, and I would guess Windows 7 also, machines from Dell, IBM, HP and other OEMs use a partitioning scheme built into Vista that is not standard partitioning. If the Vista partition is moved to a different place on the disk, or placed on another disk, it won't boot.

XP partitions work with dd.

In the OP, I mention making an .iso image file from a CD. But the CD is already in .iso file system format. So, the resulting .iso image is just a copy of the CD. Dd will not change everything into iso9660 file systems. Whatever the file system is, it stays that.

To make an .iso image out of some files, you use genisoimage. That will produce an .iso image that will burn to a CD as an image.
