I have a 3 TB 3.5 inch Toshiba Canvio external hard drive which I've formatted as a GPT disk in order to use the full 3 TB. I've found that with Seagate 3 TB and 4 TB external hard drives even if you use GPT if you remove the hard drive from the external case and try to use as a regular drive Windows 7 sees it as unformatted so the data stored on it can't be accessed. I believe this caused by some trickery in the SATA/USB conversion board so that Windows XP can use these > 2 TB drives.
I've had external hard drives fail before because of a bad power supply, bad SATA/USB converter board but when I pulled it out of the external case the bare drive was seem by Windows 7 fine with the data stored on it intact. Is there a software program that can read the data on the bare drive even though Windows sees it as unformatted?
