He everybody,

The title should read "partition list is too small".

I have a 3 TB Seagate USB hard drive connected to my iMac. It has a library of normal (so .avi, .mov etc) and MKV videos on it. I have the hard drive since a few weeks. I use PS3 Media Server to stream it to my Playstation 3.

Since yesterday it stops playing the files after some time. Then when I go back in the folder it shows that the file is broken. Trying other videos, they all are broken as well.

Anyway, apparently, the drive disconnected from the iMac (when I went go to check the settings in PMS, the first thing I saw on my screen is that I disconnected the drive in a "bad" way, the message when you get when you disconnect the drive without ejecting it in Mac OS X).

As you might understand, I did not disconnect the drive. So I went to check the hard drive using disk utility. When I check the partition on it, there's nothing wrong. However, when I check the disk itself it says the "partition division (this is roughly translated, but I guess it's "the partition list") needs to be restored because a problem occurred with the system file from the EFI-system partition".

So basically, I think this message is the problem. Pushing the "restore disk" button did help. But now it says the EFI partition list is too small and still needs to be restored. Pressing the "restore disk" button now doesn't help. So how do I make this partition list correct?

I know I could transfer all the files to some other drives (which would be a hassle, because I don't have one TB free on any of my hard drives, so I would have to scramble the files over my hard drives, and then later put them back and remove them), but I'd rather not.

At the moment I'm doing a deep scan with Data Rescue (some website said it could help). However, how can I rebuild the list with that afterwards? Is it even the list I need to rebuild or something else?

I checked this website: http://www.andreas-hess.info/programming/testdisk/index.html

But I couldn't figure out (I'm not a terminal hero) how this program could restore the partition list.

So any help would be great.

P.s. the hard drive itself has a GUID-partition table.
The partition created on it is Mac OS Extended (journaled). With which is nothing wrong.
