We connected an old  Xebex S1410 SASI controller and a
CMI CM5619 19MB (unformatted) hard disk to an Macintosh SE HD. (we configured
the drive as number 1).

Then we used the SF&I program of mister Vishniac to format the disk. It
actually worked !. We made our own Mode Select Command to set up drive
parameters as nr of cylinders and nr of heads.

After quitting the programming the drive was mounted and an icon showed
up on the desktop of the finder.  We copied files to it and everything seemed
to work just fine.

But... when we tried Apple utility 'Apple HD SC Setup' it didn't recognize
the drive, and when we rebooted the Mac, the drive would not mount.
The disk seems to be recognized only directly after formatting with SF&I.

Some additional remarks:

* We tried both the driver of mr Vishniac (made for Rodime 652 disks) and 
the driver from Apple as supplied in the 'Vanilla' resources. No differences
noted.

* We know there are some known problems with short scsi-reset timing, but
what can you do about it.

* SASI <> SCSI, we know. For example we did not connect
the ATN (Attention?) line from the Mac scsi-bus to the Xebex controller.
Should it be connected ?

* We plan to use the drives (that we can get for free...) with our 512e
mac,  with a Dove SCSI controller installed. Does this make any difference
with connecting the drive to an SE ?

* When the Mac fires up (we use sys4.1/finder5.5) the harddisk
frontpanel-light lights up. When running the Apple HD SC Setup, it
lights only short and very dimmed (very short pulse, we assume).



So here's where we're stuck. We surely don't want to reformat the drive every
time we boot :^)   so anyone knows of a solution ? 
We appriciate any hints or tips or drivers software (either binary or
c-source ). We do have both 'electrical mac' articals of MacTutor.
