crashed partition-table

[jack renders <j-renders@xxxxxxxxxx>]

I just recently partualy crashed the partition table of my HD  when 
running qtparted ( was resising hda1 but entrys of hda5 and hda6 were 
deleted)  and I backed up data from hda1 to hda5 before running qtparted.
As is was a lot of important data to me, I want to try to get it back.
I read a thread on your mailing list, but I was wondering if you could  
explain this solution in a beginners way, as I 'm a newbie to repairing 
filesystems ( no newbie to linux )

Try to find the start and end of every partition, use dd to dump each of
> them in separate files and mount them as loop device.
I found XFS superblock, dd-ed whole partition and now my all important
data is back :-) Thanks for help.


If I find the superblocks  which commands do I exactly use to " dd " the 
whole partition and get the data back?
Do I need to run the xfsprogs  commands from a floppy or can I use 
knoppix-liveCD?
maybe there is a howto on partition recovery for XFS-filesystem for 
newbies you can point me to?
Hope you can give some help as I don't know if this is the right way to 
go for help on this matter.
