---------------------------------+------------------------------------------
 Brand new SanDisk Cruzer 4G USB FLASH Drive.  Formatted FAT32 out of the
 box.  Never been written.

 Using Q2E41 on XO-1.

 {{{
 ok select u:0
 ok load-base 200 read .
 ok load-base 200 dump
 ok unselect
 ok " u:\mbr.bin" $new-file
 ok load-base 200 ofd @ fputs
 ok ofd @ fclose
 }}}
 the fclose command hangs

 abort with frame key

 {{{
 ok dir u:\
 }}}

 hangs

 reboot

 {{{
 ok dir u:\
 }}}

 shows mbr.bin, 0 length

 {{{
 ok rm u:\mbr.bin
 ok writing u:\mbr.xxx
 ok load-base 200 ofd @ fputs
 ok ofd @ fclose
 Flusbuf error
 ok dir u:\
 }}}

 Shows mbr.xxx, 0 length

 Retried the above sequence on XO-1.5 with Q3A35 - same result (flushbuf
 error).

 The MBR is all 00 except for one partition entry:

 00 00 27 00  0b fe 7f e7  26 00 00 00  c2 9f 77 00

 and of course the 55 aa at the end.
