Fitting a SCSI2SD in a 68k Mac

@BL!

1/ Is the device terminated? Check the box on the 'general' tab of scsi2sd-util

2/ If you're using the unpatched version of HD SC Setup, you can only format drives that have the apple firmware. How did you configure the vendor and product IDs on your SCSI2SD?

From the OP:

  • Then, you need to setup the parameters of your SCSI2SD: As far as I can gather, there is no need to change any of the 'General' settings for a 68k Mac, but you do need to change settings in the Device tab for the system you are using. Detailed information can be found here, but essentially you need to con the Apple SC HD setup software into believing your SCSI2SD is a valid hard drive. To do this, you need to do the following:


    Set the vendor to the string " SEAGATE" (yes, there is a single space in front of SEAGATE for a total of 8 characters)
  • Set the product ID to the string "          ST225N" (10 spaces in front for a total of 16 characters)
  • Set the revision to the string "1.0 " (with a space after, for a total of 4 characters)

From the OP:
I used the utility for Windows to access the card via the Micro USB interface on the card. I've done the settings and saved them to the card so that works (if I read them I get the same back).

The HD setup doesn't see a SCSI device at all, is that normal? I'm thinking that if it was a size issue it would still pop up on the SCSI device list but maybe not usable, or?

Also, the red LED starts flashing basically immediately upon powering on the SE/30.

So you have the correct settings and it still doesn't show up? Have you tried another utility like Lido?
Yes, I think I have the correct settings (tried a couple of different ones as well).

I'll see if I can get Lido onto a diskette and try that.

If you need any disk images to be made, I can easily do that for you. Lido would be the way to go if you can get it onto a disk. I would also find a copy of SCSI Probe to see for sure if you can get the SE/30 to see the drive. One last thing: was the internal HD working prior to this? Can you attach any external SCSI equipment? The other possibility could be a malfunctioning SCSI system.

Yes, I normally have a SCSI drive attached (at this moment a Quantum 500MB) and that works so at least the internal bus is fine (haven't tried the external port as I don't have any external SCSI device).

Ok, so you pretty much ruled that possibility out. I would again check with SCSI Probe/LIDO and see what it is that you find, and then hopefully we can help more from there.

SCSI Probe (thanks a lot LaPorta!) found the card which I presume is good news! :) I will double-check the settings once again. There are plenty of other options that might or might not be checked/enabled as well.

This is the settings I'm having now (should I alter anything?):

I will send you Lido as well in a bit. If it can see it, you may be able to format it.
I'm actually accessing the SCSI2SD right now with the Apple HD SC Setup v7. 3.5 (initializing right now), so happy days, real progress being made here now!

:)

I wonder if it was the space in the version number or something?

Thanks for the help, guys!  ;)

THat's usually the way to go: formatting the SD card either on the machine it will be used with on the  SCSI2SD or equivalent seems to be the easiest way to go about it.

I swear this "simple project" is going to kill me.

Now I'm the proud owner of a 3.5" floppy drive and a bunch of disks. I fired up Macdisk, formatted a floppy and copied over System 7.5.3 Disk 1. Macdisk asks if I want to break the .bin? Sure? Macdisk crashes.

Ok. Let's try again. No don't break the .bin. File copies to the disk and the mac wont boot.

So .bin must not be the preferred file format. Except no compression program I've tried on Windows or OSX will uncompress these files.

Has anyone got any ideas?

They extract an .smi file that I can't open either.

Windows, OSX, and Basilisk can't open these .smi's. Actually Basilisk can open it but I can't extract a usable format to copy to a floppy.

I can't be the first person to ever try and copy to a physical floppy.

An SMI is a Self Mounting Image (disk mounting app and disk image bundled into one), not sure if you can do anything with those on a modern machine... It looks like there are regular images for System 7.5 here:http://www.macgeek.org/downloads/ Maybe try "DTools75.zip". My MacBook Pro (macOS High Sierra) unzips that one to a folder with an .img file that it can actually mount.
