Error with Android usb. Working Macintosh HD not repairable. Alternatives to backup? I have to say first, I have almost zero experience is the use of Terminal, an usually I'm very careful with what command I use.

I have tryed to create a bootable Android x86 usb and it was a success, it booted perfectly on a windows pc. I hope it worked on Mac too, sadly it was not.

But I immidiatly(usually shut the Mac once a week) discovered, by that boot try, I did something wrong. A slow grey loading bar appeared at the start up!
Before realizing the bootable android usb (with UNetbooting) I tryed a terminal operation I saw on youtube and in another thread

sudo DiskUtil UnmountDisk disk1s1
sudo dd if=/Users/Me/Desktop/android.iso of=/rdisk1s1 


(I get now it was correct of=/dev/rdisk, right?)and I use it three times, without any results, I thought.So, after the long slow bar, I tryed to verify disk with Disk Utility and found I need to repair.

Booted my install CD and before I opened Disk Utility notice in the choice of partition install Macintosh HD was not appearing, just my Vista partition.

Disk Utility sadly sad me it was beyond repair and needed a backup. I did it twice, one with SuperDuper! (who was even faster than Time Machine, who started even long before I downloaded SD!).
But I'm not ok with this. I find here this

df -hl


and

sudo fsck_hfs -l /dev/disk0s2


with, again, just the repair advaice.

Even noticed the three tries were placed at Macintosh HD folder with  lost+found and  DamagedFiles folders, all created at the same time.

So I hoped deleting them the problem could be solved. No, it isn't.

Still I transcripted the 2 damaged files in the folder who are

.DSIsRunning            Macintosh HD/Library/Prefences/DirectoryService


utmpx                   Macintosh HD/private/var/run


Now. My only chance to set everything back, even if my Mac still works without any defect sign (expect the long startup), is just to restore backup or else?
Just me! Apparently choosing a password not as soon as possible assigned me another user (former user127893, now user128454) but still same username and almost similar avatar (a quarter or the former with a more visible Triforce :D )

BTW recently I tried to run a Disk permissions check and repair. After that I repeat the Verify Disk and the error message changed (if I remember well it wasn't like this) incorrect number of thread record.

Hope if I retry a repair this time I'll have some luck.

P.S.:I'm a bit surprised of this did't get much attention and I'm gonna search mmore about Buscar웃SD suggestion. I wonder if I need to apply Cunningham's Law (the best way to get the right answer on the Internet is not to ask a question, it's to post the wrong answer)
