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)
RAW mode is for advanced users. There is no speed advantage to using this over file based images and setup is much more complex.
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 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
This is a work in progress and not in a release yet!
It is useful to create a small initial FAT32 partition of at least 32MB for configuration and log files used by BlueSCSI.
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
It is useful to create a small initial FAT32 partition of at least 32MB for configuration and log files used by BlueSCSI.
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.
