If no luck head for drivesavers.com or ontrack.com for a paid service.
And, sorry to note, there are many stories here of people losing the data on an (external) hard disk if they forgot to make copies or backups. You wouldn't be the first, and you won't be the last either.
This is my desperate call for help.... I almost had 1 TB of data on my WD MyBook external HDD and one day it just vanished in a matter of seconds. I need help in recovering my data. Please tell me how should i go about doing it. I have not copied anything onto the HDD yet nor done anything to it. I have tried just Handy Recovery v4 and another called Migo Recovery.
How it happened :
The HDD was connected to my PC having AVG Antivirus. I inserted a pen drive which belongs to one of my frns and copied data into the HDD. I see a flicker on my screen and 1 TB HDD displays around 932 GB of free space. I dont knw what has happened. Please HELP !!
