I have downloaded IOATABlockStorageDriver code from Darwin site. But after going through ioregistry I came to know that IOATABlockStorageDriver is layered below IOBlockStorageDriver which converts ATA specific read/write requests to generic read/write requests. Whereas I want to write IOBlockStorageDriver for SCSI devices. It's not quite clear what you mean here.
Are you attempting to write a driver for a SCSI controller? Or are you trying to intercept block I/Os, but only to SCSI devices?
