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)

⚠️ Warning:

RAW mode is for advanced users. There is no speed advantage to using this over file based images and setup is much more complex.

📝 Note:

You will not be able to use many of the advanced configuration or other features of BlueSCSI in RAW mode.

Full SD Card

The simplest way to use RAW mode is to place no image files 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.

Note there will be no log file - logs will only be available via Developers-(Advanced)#usb-serial-debug logging.

Partitions

Create a small FAT32/ExFAT partition at the beginning of the card. This will store the Bluescsi file and the log file.

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

[SCSI2]
IMG0 = RAW:0x12345678:0x22345678

[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.
