Which Macintosh computer are you using?

Which Macintosh computer are you using? I have a scsi2sd card running in my Mac SE/30. I believe you need to install the scsi2sd card and format for your version Mac OS then use floppy disk iimages to install your desired Mac OS. In my case, I installed Mac OS version 7.1

It depends on your device. 

It depends on your device. 


An actual scsi2sd has a config utility to set parameters on the device for how the SD card is seen by the scsi host and what blocks of the SD show up as a hard drive. The Mac can and will format and use said hard drive(s) normally. 


The newer devices like the ZuluSCSI use disk image files on a FAT32 or exFAT SD card. The file name of the disk image determines how the SCSI host sees it, i.e. hd0.img is scsi ID 0 and will act as a hard drive. You can use preformatted images with these with relative ease, where a SCSI2SD would require raw copy to the correct sectors. 


Both have their advantages, SCSI2SD is no longer made.
