Running a non-reformatted disk through Dave G's mfm device got me the
following after running a mfm_write to the whole disk followed by an
mfm_read:
Expected 312120 sectors got 311766 good sectors, 282 bad header, 72 bad data
0 sectors marked bad or spare
49 sectors corrected with ECC. Max bits in burst corrected 2
Track read time in ms min 18.260750 max 2098.231833 avg 35.600018
So.... 354 bad sectors, and 49 more that were only readable with ECC.
That's not too great, I think I'll shelve the Maxtor drives and just go
with ESDI when needed. Those seem to be a *lot* more reliable than MFM.
