 MESSAGE
     WRITE ERROR

 DESCRIPTION
     Too long data block.
 
     The controller attempts to detect the sync mark of the next header after 
     writing a data block. If the sync mark does not appear within a 
     pre-determined time, the error message is generated. The error is caused 
     by a bad disk format (the data extends into the next block), or by 
     hardware failure.
