RAW Mode


RAW Mode allows you to use the entire SD Card as a drive or partitions of the SD card as the drives instead of file based images (think the way the old SCSI2SD’s worked)

Full SD Card

The simplest way to use RAW mode is to place no image files and one partition on the SD card. Upon startup the entire SD card will be presented as a Fixed Disk at SCSI ID 1 with a 512 block size.

In this mode here will be no log file - logs will only be available via Developers-(Advanced)#usb-serial-debug logging.

Automated Partition Discovery on MBR Cards

BlueSCSI will automatically find the partitions configured on your drive.

If you would like to use the first partition for configuration and logs you may set SkipFirstPartition=true in bluescsi.ini.

MBR is limited to 4 partitions.

Manual Partitions

Create partitions you wish to present as SCSI ID’s on the rest of the card.

Find the Partition offsets, you will need them to setup the bluescsi.ini file. Partition offsets can be found in most disk utilities or use the automated partition discovery above.

[SCSI2]
IMG0 = RAW:2048:32678

[SCSI4]
Type = 2 ; CD
BlockSize = 2048
IMG0 = RAW:0x22345679:0xFFFFFFFF ; Remainder of SD card, calculated automatically

Silly Things

You can use file based and RAW mode at the same time - though I’d backup your data before attempting.
