Maybe it's also worth trying to find one of the alternate superblocks.
If you used ext2/ext3 then a "mke2fs -n ..." will tell you where htey
could have been and a "e2fsck -b ..." will use them.

There could be also tools around to search for superblocks by their
"magic number", I can't find one right now but maybe the
afore-mentioned sysrescuecd includes such tools.

I've just had a dig through the kernel sources and I didn't complete
it but I think I can write you something to lookup blocks with the
magic number in the right place if it comes to that.

Cheers,

First of all, you need to make a byte-to-byte backup of your external  
hard disk.

A single 'dd' command will achieve that.

Then, if you can remember the original partition scheme, try to  
manually restore it. Hopefully most data can be found with minor  
inconstancies.


BTW There was a thread on 'Recovering data from failed hard drive'  
around 1 December 2008, and it may be useful to you.

Maybe you'll have better success with google if you spelt it "latex"
and "bibtex".

[SLUG] referencing lyx jabref bibtek

2008-12-22 Thread Ken Wilson



I am having trouble getting references in the format required for my
partners thesis.
Using lyx as a frontend to latek, and jabref as a frontend to bibtek.
Using Natbib style of citations.
currently getting
 Author (year)
would like
 (Author, year:page)

I have read the tutorials in lyx, and jabref, googled, installed extra
packages for jurabib and natbib styles, tried all the obvious menu options.
I am thinking that it is probably a bibtek preamble to the document that
is required. Any pointers from here.
Cheers

Re: [SLUG] How do you un-partition a HD

2008-12-22 Thread Kevin Shackleton
Try SystemRescueCD to see past the new header structure and find if
there are any files left.  It's a bit user-vicious but you'll manage . .

Maybe an addendum to Mary Gardiner's story on external backups:
"unplug drive"

I have a home external drive kept at work, against moments of weakness
such as these.

Good luck.

Kevin.

Re: [SLUG] How do you un-partition a HD

2008-12-22 Thread Ken Wilson
If you stopped while just arranging where you wanted the disk 
partitioned, nothing has been written to the disk.
If you actually proceeded with partitioning the disk then all the disc 
has been overwritten in the formatting of the disk/partitions, and data 
recovery would be very difficult and expensive if someone specialised 
does it.
If you accidentally partitioned your external drive rather than your 
internal drive, then the internal drive should be OK. Make backups and 
start again.
You dont so much unpartition a drive as delete partitions and 
repartition again.

Hopefully there are other backups.
cheers
Ken
