Hello,
I would be very grateful for any help that someone can offer me with the following problem;

I have a Seagate Barracude 3000GB HDD, which I have formatted using Windows 7 Disk Management as a GPT Drive. I then placed the drive in an external USB cradle and have been using it to store photographs and some videos I am doing for a project as I am working between two machines. Till today I have no problem with either machine or the drive itself. Both computers have recognized it as 3000gb GPT drive, and I have been able to store, add and amend data as normal.

This morning whilst working we had a power cut and the computer went off with the drive, when powering up I did not disconnect the drive from the USB port, and whilst in startup mode Windows identified a possible fault with the USB drive and ran the check disk programme it runs at startup, and has reset the the drive as a 760gb drive, thus removing the GPT ID. I have tried both computers and neither will read the drive saying that the disk needs to be formatted??!!??

I am assuming the data is still on the drive as the programme check lasted all of 2 seconds, but how to I re-access it? Do I use Windows 7 Disk Management to say it is a GPT drive or will I lose all my data.

So far I have done nothing except switch off the power and unplug the drive, and I am hopeful that someone can offer a simple solution that will allow me to re-access my data.

Thanks for any advice.

Regards

Tom

Hi, you can use a program called R-Studio, use google to find.
Take the drive out of the cradle and plug it in to the mainboard via Sata connector and then scan the drive for lost data.

Hello,

Many thanks for your comment.

I placed the disk drive within the computer cradle connected via sata connector and downloaded R-Studio. Maybe I am missing something but R-Studio is very complicated and I have been unable to get anywhere.

I have tried proprietary recovery programs but they only seem able to locate around 60-70% of the original data, so where has the other 30-40% gone. As I understand it Windows Chkdsk would have changed the FAT Table and maybe done a quick scan which should not have dumped a large portion of the data.

I cannot believe that this has not happened to someone else, I am sure there has to be an easier solution to this problem and one that recovers a higher portion of the data.

All comments thoughts greatly received.

Thanks again.
