   That worked Larry.  I've got my drive partitioned with CP/M on the first   
   partition and LDOS on the rest.  Of course, I'm not getting the full   
   amount of disk space out of the CP/M partition as the 5mb drive has 4   
   heads and the 12 has 6.  So ultimately, I'd still like to find a copy of   
   the driver.   
      
   I tried copying some files from a floppy to the CP/M partition and some   
   worked others repeatedly gave disk error F.  According to my manual,   
   this is indicative of a hardware failure.  I'm thinking it make be   
   because I'm using the wrong driver for the hard drive.  Any thoughts?   
   Should I be asking this on a CP/M newsgroup instead?   
      
   Regards,   
   Doug
