This is a premature end of file error.

Try TPHEAD or PRTTP on the file.  If you send me the output from these I 
can make a guess as to how big the file should be and you can check to 
see if it is this big.  I suspect that the file was truncated in the 
copying or creation (which depends on casa).  Usually we get a message 
about wrong number of bytes in a record but I suppose it is possible to 
truncate exactly on a 2880 byte boundary.
