There are a lot of things going on here and I’ll only comment on a few:

Then….

1. Make sure you’re running the latest ZuluSCSI firmware from GitHub.com.

2. Stop trying to use the bare SD card as your virtual drive, all ZuluSCSI should be able to be used in raw SD mode or in file mode. It’s much more normal to properly format your SD card in your PC and then create image files for each of the virtual SCSI drives you want. For example, if you wanted a 4 GB virtual SCSI drive on ID1 you need to create a 4 GB file on the SD card for it to read, it’s a bad idea to treat the raw SD card as the actual drive the Indy will see. So the file would be named hd1.img on otherwise normally formatted SD card that your Mac or PC can read. To be extremely clear on this the SD card is formatted exFAT, it will contain one or more image files that you need to create. Your PC will not intrinsically be able to read the contents of these virtual Drive files. So expect that you’ll be able to copy, delete, or create these files using your standard PC, but that doesn’t mean that the PC will be able to crack open these image files and read individual files from a specially formatted SGI Drive image! An analogy might be that the formatted SD drive is like a basket and the virtual Drive files are like eggs, you can add or delete or copy as many eggs as you want (up to the SCSI bus address limits), but you may not be able to crack the egg open and look at the contents inside. They may require to be read by the original machine that formatted them for them to make any sense. So do not assume that you can use them for data transfer from your SGI Indy to your PC by simply reading the virtual Drive file on your PC. It won’t work, as a PC has no knowledge of how to read an SGI formatted drive and file system.

3. To ensure that you’re formatting your SD card correctly there is an official formatting utility from the SD card association available from their website for Mac and Windows. But you can certainly try using the standard format in your computer, please use exFAT as the preferred file system.

4. if you’re current raw emulation is showing up as ID1 then why would you set it for ID2? File name normally overrules the manual setting.

5. Don’t ever use the AUTO option in FX. It doesn’t do what you think it does and it definitely won’t work on an emulated drive. The AUTO option runs the low level SCSI format on a drive before partition. That’s not something you ever want to do normally. Please just use the create disk label command and create a root drive. For an emulated drive please re-create or keep a copy of the empty zeroed Drive file between FX partitioning attempts. You’ll likely find it easier to keep copying over an empty drive image to the SD card than to keep reworking old file system, and partitioning attempts if you’re just starting out.

6. Ensure that you can read and write to your SD card and that you have not accidentally engaged the lock tab on it as the adapter will respect the lock tab. Also the link given above talks about proper SD card classes and speeds. Please make sure that you’re adhering to that advice when choosing an SD card.
