How to setup an SD card to mount multiple SCSI virtual volumes

Tested witha a BlueSCSI 1.1a DB25

Based on the instructions on the Kurzweil's documentation for SCSI drives 4 drives of 2GB each were created, on the LUN0 and assigned them to the SCSI IDs 2,3,4, and 5 to avoid conflicts with the ID 6 which is the default for the Kurzweil instruments, ID 1 which is usually the default for internal HDs, and ID 0 for communications with external computers.

The procedure used is as follows:

• On Linux, execute the following commands to produce the needed volumes:

$ dd if=/dev/zero of=HD20_512.hda bs=4M count=512
$ dd if=/dev/zero of=HD30_512.hda bs=4M count=512
$ dd if=/dev/zero of=HD40_512.hda bs=4M count=512
$ dd if=/dev/zero of=HD50_512.hda bs=4M count=512

• Once the volumes are done, format the SD card as ExFAT and then copy over the images into the SD card.
• Umount the SD card
• Plug-in the SD card to the BlueSCSI, hook up the BlueSCSI to the Kurzweil and then power up the Kurzweil.
• Once the unit is on, press the "DISK" button, and go to the SCSI ID 2
• Format the volume, do not partition it, unless you created the volumes larger than 2GB
• Repeat the steps 4 & 5 for SCSI IDs 3,4, and 5
• Turn off the Kurzweil, detach the BlueSCSI from the Kurzweil, take the SD card and put it back on the computer
• Mount the SD Card
• Mount the first volume (Assuming that you labeled the SD Card BlueSCSI)

$ sudo mount /run/media/$(whoami)/BlueSCSI/HD20_512.hda /mnt/

• Copy all your files into the /mnt directory

$ cp -r /path/to/my/samples /mnt/

• Umount the volume

$ sudo umount /mnt

• Umount the SD card
• Plug-in the SD card to the BlueSCSI, hook up the BlueSCSI to the Kurzweil and then power up the Kurzweil
• Turn the Kurzweil on again, press "DISK" button, and go to the SCSI ID 2
• Press the soft button "Load" and you should be able to see your files and navigate through the volume on the SCSI 2
• Select your samples & programs and load them
• Play the samples at the selected location and there should be no corruption, ie, no crackling sounds, unless the sampling RAM is defective
