Hello and thanks for looking at this thread for me! Basically I have a 1TB Samsung external hard drive that I've had since last year, and everything has been fine with it, until about one week ago. The hard drive is roughly half full (500GB) of data etc. When I connect it to my Macbook Pro it comes up with some message (Can't remember exactly what, but something along the lines of it can't read it) and then also does the following... When I enter iPhoto (my library is on it!) it says it cannot read the drive as it is 'locked'... If I try and verify in disk utility it says 'Live file system repair is not supported'.. I cannot change permissions as it's 'read only' in Get Info.. Any ideas? It's formatted as FAT32, if that makes any difference? Thank you for ANY help!
