Mac SE FDHD worked with SCSI2SD - now it won't boot from it


Recommended Posts

Strange issue here...maybe someone can help.

 

I have an internal SCSI2SD on my Mac SE FDHD. All was fine in the world and the Mac would boot from the SCSI2SD SD card with no issues. Today, I turn the Mac SE on and I get a blinking question mark. Strange... so I boot the Mac from a floppy Systems disk.

 

Once the Desktop loads, I can see the SCSI2SD volumes and all its data appears intact. Rebooting the Mac yields the same issue. It will bypass the SCSI2SD and hang at the question mark. 

 

I've made no changes and yet the SCSI2SD does not boot. Anyone have any insight on what to troubleshoot?

 

Thanks!

If you can see the SCSI2SD volumes, it  is more likely to be a software issue. Do different SCSI2SD volumes have different System folders you can use (e.g. use the application "System Picker" to select the volume and specific system folder to boot from...). On my SCSI2SD I have different volumes with different System versions, and I can swap between them.

I would recommend trying to set up another SD card with the SCSI2SD and seeing if you can get it to work. It is possible the card you have installed now has become corrupt, and it needs to be reformated. If you can still read data from your current drive, I would highly suggest copying it onto a Zip Disk or something similar before it is potentially lost.

This sounds like the boot blocks on the SCSI2SD to me.  I had a similar issue on a compact with a SCSI2SD, actually—when a specific application crashed the machine, the boot blocks got scrambled, and I had to re-bless the System Folder.  When it happened to me, no other data on the drive got corrupted, but I wouldn't want to bank on that, personally.
