If you have a 3TB HDD, you need 1 or 2 more of the same to be safe that hold the backups.
https://www.google.com/search?q=Invalid+sector+size%3A+0&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=rcs shows this is not a new issue. I can't guess if you used exFAT or some sort of FAT but that's too dangerous for me. I would avoid all FAT file systems in the future.

Hi, hope someone can help me out on this. I have a MacBook Pro with Retina display (OS X, 2.7 GHz Intel Core i7 processor, 16 GB memory). I recently purchased a 3 TB G-DRIVE with Thunderbolt External Hard Drive which I've been editing off of for the past 2 months.
Yesterday I took an hour break from working on the drive. I safety ejected the HD and turned it off but an hour later when I went to turn it back on my mac wasn't able to read the drive. I went into Disc Utilities where it recognized the drive but wouldn't allow me to manually mount the drive. I then attempted to repair the disc via Disc Utilities but it gave me the following warning:
"Verify and Repair volume "disk1s2"
Checking file system
** /dev/disk1s2
Invalid sector size: 0
Volume repair complete.
Updating boot support partitions for the volume as required.
Error: Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Is there any way to repair the disk without it being mounted? And if not, is there anyway for me to backup the contents of my external hard drive before I reformat it? Thanks
