I'm having troube with the "scsi.device" which has replaced the "hddisk" device on the 3000. I am trying to use the SCSICmd structure and cannot send more than 256 bytes or else the system hangs with the HD light remaining on. Setting up a data buffer with a byte pattern as follows: 01,02,03,04,05,06,07,08….. the output consists of bytes 01,03,05,07… skipping every other byte. It appears that the AMIGA thinks it read 512 bytes but the tagret device only receives 256 and ties up the scsi bus requesting the remainder. This problem is duplicateable in C and assembly. I know that the target device functions properly as the asme testing on another type of computer results in correct operation. Any ideas or help would be appreciated. Harry M.
