Bought this HD a few weeks ago, I'm running Windows 7. The problem is that when I restart around 2 or 3 times the HD is completely unrecognised by Windows, it doesn't even show up, but when I format the hard drive in GParted and start Windows again, it recognises it fine. I've tried formatting it as NTFS and exFAT, as well as ext3 and using some ext3 for Windows program. The only thing that seems to work is formatting it as FAT32, but obviously this is impractical due to the 4GB file limit.
