Quick question for #retrocomputing ... it's my first time setting up a classic Mac with a zuluscsi SD card “hard drive”. I assumed that formating the SD card as HFS would be best for performance, etc - but then it's hard to read/write to it on anything else.
How well does the fat formatting and using hda files as SCSI devices work? Can I write to it and it'll just expand the image file as needed?
@jonschwenn The FAT formatting with HDA files works well. exFAT is the recommended file system for the SD card, supposedly much faster. With HDA files you can have multiple SCSI “devices” on the same SD card. You’ll create an HDA file of the desired size (2 GB is a mostly safe default size), and on the Mac you’ll format that as a new HFS hard drive.
ZuluSCSI manual is here if you haven’t seen it: https://github.com/ZuluSCSI/ZuluSCSI-firmware/wiki/ZuluSCSI-Manual
A lot of the BlueSCSI documentation regarding image files is useful too.
