Disklavier

I recently  traded my Yamaha DC3IIXG disklavier for a DC3A disklavier. 
 When I began loading individual songs into the flash memory of the DC3A 
I discovered  after loading up memories 0-A that I received an error 
message which stated simply "An error has occurred".  Furthermore, if I 
tried to load any further songs into the DC3A's 16 MB of flash memory , 
I received the message "Unformatted memory disk" and I could no longer 
access any of the songs that had been stored in that memory disk nor 
could I pass the "unformatted memory disk" memory slot by cycling 
through the drives from either the control or the remote. When I 
attempted to format the "unformatted memory disk", I got the message 
"Cannot format disk".   Consulting the manual, I learned that when you 
get the "Unformatted memory disk" message, your only recourse is to 
reinitialize the memory to the factory defaults.  This, of course, 
erases all of the songs in all the memories and means the loss of 
several hours of work.  

I reported the above problems to Yamaha service in California and they 
were very good at working with Japan to prepare a flash memory upgrade 
that will solve the problem.  It turns out that the memory architecture 
of the DC3A is arranged differently than that in the DC3IIXG and 
differently than described in the manuals that came with the DC3A.  In 
the DC3IIXG each memory held 1 MB of data and hence one could fill all 
16 of the memory slots with songs before receiving a "memory is full" 
message.  With the DC3A. each memory slot holds approximately 1.4 MB of 
data and hence one can fill  only 11 memory slots before getting the "An 
error has occurred" message .  This latter message and the consequences 
described above after receiving this message are a reflection of a bug 
in the firmware which Yamaha has now corrected in the V. 4.32 Control 
software on their web site.  Apparently I was the first person in the 
U.S. to attempt to fill the memory slots of the DC3A because the folks 
at  Yamaha in California stated that they were unaware of the problem 
previous to my pointing it out to them.  

I would urge those persons having the models of disklaviers in the title 
of this e-mail to download ( 
http://www.yamaha.com/ycaservice/group005/fgrop005.htm ) and install the 
4.32 Control firmware upgrade which corrects the problem described 
above.  I have done so and I can verify that one now gets the message 
"Disk is full" upon reaching the 16 MB memory limit and there are no 
problems getting the dreaded "Unformatted memory disk" message and 
subsequent events described above.  

I am grateful to Yamaha for their quick and thorough response to 
addressing this problem when it was pointed out to them.
