Dan,
Head thrashing generally means the drive is doing lots of retries
(or the system is requesting lots of retries). One thing that can cause
that is the drive mechanically becoming slightly out of alignment (due to
age) and a low leve format can cure that. I've seen similar problems on
drives at work, and a low level format fixed it. The drives at work were
SCSI drives attached to minis.
It's certainly not the only thing though that can cause it.
As I said in my message…I wasn't aware of what blind reads were.
Now one place you say they're non-error correcting and in another you say
there is no handshakeing. Those are two different concepts…which did you
really mean?
Don
