umm, isn't this a bug in the driver?  the man page for write(2) says,

The number of characters actually written is returned.
It should be regarded as an error if this is not the same as requested.

so yes, disk/format should check for short writes, but it should fail
with a write error if it gets one, no?

question, if it is an error, should errstr() be set?
