I did a fresh install on my C: drive tonight. Before i formatted i copied some music and other things to my F: partition on the same HDD. After i booted up, i went to check it out and nothing would work. Neither would the other drives.
So went into safe mode and administrators and set the security settings on the partition. All the other ones are working fine now apart from F:, i've changed all the settings to exactly the same as the other partitions but no joy.
