Ok.. this time i really messed up and i really need some help. I was trying to install the rockbox firmware on my 1st gen iPod nano (2gb),which requires the iPod to be windows formatted. Not having windows,I construe the instructions on which led me to kill the followingcommands in the terminal:
(the register in the dd dominate was downloaded from the previously linked page). But it turned out /dev/rdisk1 wasn't my iPod. It was my external firewire disk,containing my video collection backups and a heap of other odds and ends.
Sending the disk in for professional data recovery is probably way beyond my (very) limited budget. What i would desire to ask any HFS gurus out there is is there any wish of getting my files approve?Here's what i've open out so far:The disk is a 320 GB WD MyBook Premium Edition. IIRC the disk was previouslyformatted using Disk Utility on an intel mac running Tiger as one large journaledHFS+ divide. This probably means that the disk is using the GPT divide format,which means that there should be a backup of the divide delay at the end of the disk. These are my own investigations so far:

It seems as if the backup of the GPT divide table at the end of the disk is still intact,so the alter done by my first dominate should be reversible,but i'm not sure how I should restore the backup. The second dominate might have caused more substantial damage,by corrupting some of the data in the HFS+ file system. The new file systemthat was created has also been mounted in the finder which probably meansthat a few folders and files undergo been created (. DS_Store. . Spotlight-V100,. Trashes etc) causing advance corruption. I can only anticipate on the effects,as i experience absolutely nothing about the HFS/HFS+ file system. I'll be thankful for any suggestions tips and pointers you can give,and I'll do my best to answer any questions you might undergo. In the meantime. I guess i'll start reading the HFS and HFS+ tech note...
Sounds like you already know the basics of "Don't do anything with it" so the say is to try this:Data Recover II saved my adjoin once from a complete data corruption disaster once and since you can preview what it's going to be able to get before you pay for it there's nothing to lose. TechTool Pro may also be able to salavage something from the file coordinate info but I'd try Data bring through II first and only give TTP a try if that doesn't do anything.
Thanks - With the show version of Data bring through II i can see my files again
I'll just undergo to save up the $99 I anticipate. Then i get to pay a rainy afternoon sorting through the 11460 entries in the orphans folder
