After some suspicious system messages
about disk errors, the disk turned on
the "WRITE ERROR" red light.

BAND = 345₈ TRK = 0
SAR = 202₈ Took disk off-line.
That sector has a parity error on read.
Tried WRITE (offline). Got
WRITE ERROR. Both all ZEROS
and all ONES in the data register
gives WRITE ERROR. seems to be
independent of sector on that Band +
TRK. The error happened about 8
hours late; The traditional time for
this kind of thing is 5 PM Friday
afternoon.
