for a low level format you need to return the drive to the maker anda low-level format followed by a high-level format, then install the

If the directory listings were uniformly destroyed, file recovery tools
won't give you anything useful as output. But the data is still there,
you could still view the contents of text files (by inspecting the drive
sector by sector).
I see. Although how do you find a 16 digit number in a 50GB file?On Nov 18, 11:06 am, "Peter Hucker" <n...@spam.com> wrote:

Have you tried "dd"?
http://en.wikipedia.org/wiki/Dd_%28Unix%29
You can use it to write the hard drive partition to a single (huge)
file.
It might not be elegant, but if you have credit card / bank account #s
floating around your drive, dd can give this info to a bright kid with
too much time on his hands
Then why have 15 different utilities failed to produce anything at all? All that happened was a re-partition.On 2008-11-19, Nicholas Sherlock <n.sherlock@gmail.com> wrote:

it's quite practical to recover a file's contents after all the

no, just the ones you'd rather bury.Doesn't help me getting useful files back though.

I just delete everything I don't want people to see (and empty the recycle bin), then fill the disk with meaningless data (by copying unsensitive stuff over and over again until the disk is completely full). Then format it.On 2008-11-19, corgorant@gmail.com <corgorant@gmail.com> wrote:

for a low level format you need to return the drive to the maker and
they need to open it in a cleanroom...
about the best that can be done with software is to overwrite all the
data (by writing to every sector)
