Sorry if this is posted in the wrong area, just delete the post. Hi guys, Ive had a 2tb hard drive for a while, and my usb port has been broken for a while (well kinda broken) so that means that i dont have a stable connection from my external hard drive to computer, therefore hard drive always disconnects without being safely ejected. Ive never dropped my hard drive so i assume taht is the only thing that has caused my hard drive to go corrupt. Now for the details i simply try and repair the disk through disk utility as im not the greatest and i get this error. I tried messing around with terminal a bit, but it simply said "Ownership of the affected disk is required.". Basically im stuck, the hard drives files can be read, but i cant write to the hard drive. If anyone can give any assistance that would be great, i also dont really have much money to buy some crazy third party program. Again thanks in advance Regards, James --- Post Merged, Apr 26, 2016 --- Oooh important to note, i dont have another external hard drive to back up the data on the corrupted disk then reformat. So if there is a way around that you the man.
