I have a Toshiba 1TB external hard drive that was working fine on my macbook pro and my macbook air until I ran the (mac) disk utility 'repair disk' on the hard drive, did it by mistake when I was looking for a way to clean up my mac. Now the external hard drive is still recognised by both laptops, but there is no data visible. I believe the data is still there because the finder says there is 885gb available, and I have 115gb data on the drive. There's no problem with reading the drive, the blue light comes on and there are no unusual sounds coming from the drive.

Can anyone help me? Unfortunately I had just cleaned up my laptop and deleted a lot of the info I had backed up on this hard drive.

Get a file restore utility for MAC (I don't know if Recuva makes one, but that is one we often recommend on the PC side), and run that against the drive.

885 gig off a 1 gig drive is normal, you lose some though formatting and also due to the fact that a 1 gig drive is actually a bit less than that. It looks like the drive has no data. Don't try to use the drive for anything till you run the data scan for deleted files first.

thanks for the answer. i'm struggling to find a mac program for recovery, seems this is primarily encountered by windows users.

I can now see (they weren't showing up initially) a folder titled: found.000 and inside is another folder: dir000.chk and a file: fil000.chk. I am hoping these may reveal the data previously on this drive. If anyone knows of good mac software for this purpose I'd appreciate any ideas, I have been researching it all evening and not coming up with anything useful yet..
