What is System 7.5.5 Bootable SCSI 2GB disk image (for SCSI2SD, MacSD, Iomega Jaz, etc...)?

This SCSI disk image consists of a single SCSI device hosting a single bootable 2GB HFS partition (2GB is the max HFS size).  You can use Basilisk II to edit this disk image, add your favorite apps/games and any other file you want and then you can clone it onto a SCSI SD card or a Jaz drive using the "dd" command under OSX (or Linux) or by using HDD Raw Copy Tool under Windows.

Note: Basilisk II does NOT support more than 1 SCSI device, therefore you cannot use that emulator to take advantage of a larger SD card (e.g. turn a 8GB SD card into 4x2GB HFS partitions).  But for the sake of ease of use, this 2GB SCSI hard drive image should be plenty enough for your old beige 68K Mac! If not, then know that using other tools and techniques, it is possible to craft a SCSI volume table at the beginning of your SD card and then glue together multiple copies of this SCSI disk image using "dd" skip arguments (won't be possible with HDD Raw Copy Tool), resulting in many 2GB hard drives mounting on your old Mac.  This is more complicated and your mileage may vary depending on the SCSI adapter you use, but it seems to work with the SCSI2SD.
