Yesterday, my external hard drive was working fine. Now, only the boot partition is accessible whilst the main partition with all my files on it is coming up as a raw, empty drive.
I had taken it to a friend's, where I tried to access the files from a Xbox 360 and a PC. For the latter, I installed Ext2Fsd and Ext2 IFS for Windows 7 but didn't do anything that could have resulted in a formatting or loss of files. The hard drive was moved from one house to another but was extremely snug in a backpack and isn't likely to have taken any knocks.
Any clue what has happened and how I can access the files if at all? I only have access to Windows XP. It is a 1TB drive, so I can't even remember half of what's on it, let alone how to replace it!
