Can anyone confirm that a 120GB HFS+ image file works with RaSCSI, BlueSCSI, ZuluSCSI, MacSD, and SCSI2SD for me?

[MrFahrenheit]

I’m working on a software archive project. I don’t want to waste time or my own resources if I can help it.

I want to make a 120GB image file that works with all of the emulated SCSI devices. I’m told by RabbitHoleComputing that ZuluSCSI supports large volumes. Has anyone successfully created a large volume (say, 120+GB) HFS+ disk image and successfully mounted and formatted it on a 68040 and PowerPC Mac?

Is it bootable?

I’d like to verify before I … go down that… err… Rabbit Hole.

Could you partition it and make a boot and a data partition?

I've not used anything bigger than about 18GB on an 040, and that was only for testing, I tend to keep my partitions to 2GB so I can swap disks into older machines.

I don’t have or use any of those SCSI emulator devices. I know from my own use, 300GB physical SCSI hard drives work just fine in my LC475. So the system does support >18GB drives and volumes (at least on the physical level).

I just want to confirm that emulated SCSI hardware supports image files of >120GB+ with SD cards of 128GB+

I was meaning spinning disk, I don't use much else.

ive done images close to 32gb in size (was largest micro sd card i had at the time) on the bluescsi. generally any device that has exFAT support should work as the reason for adding exFAT support on these devices is really only for the larger file size limits over FAT32

Large images on MacSD are handled as MBR partitions. HFS+ or booting should not be an issue:

Here's a 206GB HFS+ volume on MacSD:

Oh, well, that's 9.1. That's practically modern.

I have a 1.5TB disk in my 9600.

HFS+ is HFS+. What difference does the OS make?

Thank you for confirming @ymk !

With HFS (yes, I know that isn't HFS+), on certain machines, System 7.1 can handle 2GB, but 7.5.2 (somewhere around there) can handle 4GB.

Sometimes OS makes a difference.

But it wasn't the OS I was joking about. The original question mentioned 040s (as well as PPC) so I was specifically thinking about what I'd tried on an 040.

So now my question is, are the hard disk image files the exact same between RaSCSI, BlueSCSI, SCSI2SD, MacSD, and ZuluSCSI?

Will the same image file work with all of them without modification?

Not SCSI2SD - SCSI2SD is raw formatting on the SD card, it doesn't work with images.

It's more like an actual hard disk... But with a weird way of dealing with partitioning, that lets you use different scsi IDs for different parts of the disk.

Okay, so what I’m taking from this is that the virtual hard disk image files are interchangeable between everything except SCSI2SD, which requires its own way of doing virtual disks?

For everything except SCSI2SD, I’ve read that you can use SheepShaver to create and setup images and then just move that image file onto an SD card to use directly. Is this true?

Sadly I don't own anything other than the SCSI2SD, I'll have to let others answer. I believe that you can't just use SheepShaver though, you possibly have to start from a disk image that has the SCSI driver and partition table on it and add the stuff you want in an emu, but I could be wrong.

I think a raw disk image should cover all of the devices. Only the method of loading it differs.

For MacSD, the 206GB partition on my card shows up as /dev/sdc2 on my machine. An image file can be loaded by copying it to that partition.
