 depends how much trouble you want to go to and in what format your files
 were. there are companies who will charge 800-2000$ for recovery...

 for a DYI-er:

 stop using the box/filesystem
 use dd or something like that to get a bit-for-bit copy of the
 filesystem. the underlying data is probably still there, maybe not so
 accessible - something like this:

 dd if=/dev/rsd0f of=/var/tmp/dd_rsd0f bs=64k

 use strings(1) and then grep or less on this to see what readable stuff
 you can get out of it. txt files will emerge quite usable, but not
 necessarily in order.

 if you need complete unadulterated data then there are a few other
 things you could try, but basically you'll need to get down  dirty with
 disk blocks.

 NB suggest using vsconfig to mount a copy of your dd file as a volume
 again, and then fsdb to see what you can recover.

ports/sysutils/sleuthkit makes things a bit easer... although you
still need to understand things about filesystems to use it
efficiently.

Forget it.
We zero block before they are marked as free in the filesystem, so by the
time you've finished writing this mail, your blocks were zeroed.

You can pay a few bazillions to Ibas and they might attempt to save your
data, but it's more likely they'll just laugh at you. And it's probably
cheaper to recreate the data from scratch anyway.

I was wrong here. I thought we did, but we don't.

So your files might still be there.

i've recovered rm'd C code using hexedit

open the disk block device, and used the built-in search, select, copy,  
and paste into new file features to recover it.


You have to know some keywords of what you are looking for, like a  
function name, etc.


good idea to leave that partition unmounted/read-only until the data is  
recovered
Well.. I got icat from sleuthkit.. right now I'm lookin' for hdd to back  
them up..

I will update this soon..
Thanks,

Insan
