Performa 475 and BlueSCSI problems ...

... my system is a Performa 475 with 128MB RAM and XC68040 CPU and BlueSCSI Desktop Version buying 2024 with two HD Images on it. HD0 with System 7.1 and then HD1 with System 7.6.1 The problem is when I use/mount the SD card with my modern macOS Computer (M4 MacMini) to add a CD image for example, and then eject it properly, the 68k Computer no longer boots.

A Sad Mac appears with "0000000F / 00000001"
or "0000000F / 00000002"
or "0000000F / 00000003" ... .

After the 10th reset via the keyboard, the Computer boots every now and then. The first aid program finds no problem.

What can I do about it?
 
In the end it even got to the point where the ID0 of the images on the SD card with ID0 and ID1 had disappeared permanently.

Everything is OK again.

I measured all the connections on the SCSI bus between the two sockets and the SCSI controller chip. Everything is OK. I had problems with the VRAM, but I don't think it has anything to do with that.


... but you never know!
 
Many missing info to answer you.
Which kind of SD card ?
What format is used on the card itself ? (exFAT is preferred)
Did you recap the motherboard and the PSU ?

Mine is somewhat sensible to the current quality given by the recapped PSU. Mostly unable to boot at cold boot but I have to investigate more.
