General In/Out error - File Corrupt

Hi there

I'm unable to open an ODS file. When I attempt to open it I get a "Filter Selection" window. The nearest choice in the list is OpenOffice.org.1.0 Spreadsheet. I choose that and then I get the "General Error, General input/output error."
I was editing said spreadsheet this afternoon and working from a Seagate 2TB slim external hard drive. I saved the file and ejected the drive from the system, but clearly I pulled the plug too soon!
I have copied the file to the desktop of my Mac, same filter,error result.
I have removed the user profile folder and reloaded OO to create the new profile folder, no luck.
I am able to open other ODS files from both my Desktop and external hard drive, so I assume it is actually the file that has become corrupt.
I was planning to take the file home to my laptop and see if it might open there, but I assume I will get the same results.
Can anyone recommend a third party software that I can try to see if the file can be recovered/repaired or are there other things I can try?
Thanks in advance for your help!

Try PhotoRec; it may recover a deleted temporary or older file.
 Edit: Generally a damaged OO cannot be repaired, no matter what one's perception of its size may lead one to believe. The best option may be an undelete utility such as PhotoRec as I suggested 
 Edit: Edit2: I'm not certain, as it is years since I had to use PhotoRec, but you may need to rename found documents of about the correct date, to type .odt (or as appropriate), to allow them be opened for checking of the content. They may be found with arbitrary filenames and file types.

Thanks Rory, I will give that a try.

I've taken a look at PhotoRecover and I have no doubt it's worth exploring, however I think using that software is beyond my skillset! I can see elsewhere that if I was a windows user I would be able to try OpenOffice Calc Recovery, but alas! Would I be better off taking the file to an expert? Are there any recommendations for those services?

The file will be broken beyond repair. You must scan your hard disk for a deleted copy. The sooner this is done the better prospects for a successful recovery.

We recommend always saving files from OpenOffice to your Desktop of one of your Documents folders. Then use the operating system (MacOS for you) to copy the file to the external drive. People seem to have fewer problems with that method.
