You will surely have to partition the 8GB card.
Connect the SCSI2SD to the USB port first then fire up the utility (either 32bit or 64 bit if using Windows - you must know this first).
Device Type: (I'm not sure here if you're using other that a computer) - I'm using "Hard Drive".
Default "Sector Size" in (bytes) should be left at 512. Your 8GB card should read a default "Sector Count" total of around 16,000,000+ bytes. Divide the Sector Count (actual) in half, or, 8,000,000+ (don't use commas) - that will give a 1st partition of 4GB. Set the "Device Size" to 4GB.
Now, "Save to Device".
If I remember correctly, I had to then click "Load from Device to see the change.
That should give you a 4GB partition.
As far as a second partition? Beats me.... I'm using mine in a 68K MAC LC III. I can't figure it out. LOL
**Based on my own info here.... I got to thinking and checked my SCSI2SD config and found a glaring error on my part - fixed it - and now have 2 partitions on my 4GB SD card! YEAH!
