Hi,<br>
<br>
there is tic tac ( <a href="http://www.tictac.co.il" target="_blank">http://www.tictac.co.il</a> ) <br>
and recover (<a href="http://recover.co.il" target="_blank">http://recover.co.il</a>)<br>
<br>
I used them both in the past. and they both offered good service,
but this service is not cheap.<br>
tic tac ares in this field for longer time, but as I recall their
price is higher than recover.<span><font color="#888888"><br>

<blockquote type="cite">Hi,

<br>
We have a 500 GB external USB drive that's about 5 or so years old
(can't remember exactly when we got it). It's now not spinning up
propperly and we figure its days are numbered.
<br>
<br>
Much of what is on it has not been backed up anywhere else (yes, I
know).
<br>
<br>
Is there somewhere I can take/send it to see if anything can be
salvaged?
<br>
<br>
Geoff.
