Data recovery from Exabyte tape

[Mark A. Saper]

Computer experts:

Has anyone ever had the situation where a small tar file was written at the 
beginning of a 8 mm Exabyte tape which originally contained one big tar file?  
Does anyone have the expertise to recover the data remaining from the big tar 
file?  

We've found a company (Ontrack Data Recovery) that will do it, but it is rather 
pricey.  Has anyone used this or any other company?

Thanks for any help.
