ALL Files Vanished - Gone!

You do understand that this is a very technical question you are asking. With most professional data recovery firms the meter starts ticking at between $1000 to $2000. Having said that let’s see what we can do.

First of all the “ST 500 000LM021” indicates a Seagate hard drive “Laptop Thin HDD 500 GB”.

You don’t mention what computer your WD My Passport Ultra is attached to but is it possible that the drive listed above is your laptop’s drive?

Recuva is good but light weight and only looks for normal deleted files. What you need is a more robust data recovery software as your partition table has most likely been altered. Testdisk is good and free but very techie but take a look:

In my professional experience, LSoft Technologies’ Active@ File Recovery, Active@ UNDELETE, Active@ Partition Recovery modules are good. They are found in Active@ Live CD. Of course you are free to choose what ever software you like. Others will have their preferred tools.

A general comment:

As I have mentioned before, these name branded external drives are the worst possible choice. Always, always purchase a SEPERATE case/controller and hard drive. Again, why? Often the branded ones have the drive’s circuit board and the USB port inbedded in the same circuit board. If that circuit screws up you are often lost. The component solution (like a good hi-fi sound systems) allows you to easily take the drive out, if the USB part goes bad, and recover your software in another system or case.
