SCSI2SD Problems After Crash

Recommended Posts

Howdy, everyone


I’ve got a PowerBook 170 equipped with a 2.5”, V5.0 SCSI2SD drive that tends to misbehave after a system crash. 

I don’t get crashes very often (only when I forget to turn off extensions that are known to cause problems) but when I do, the PowerBook will no longer boot off the SCSI2SD. 

It sits at the floppy disk icon with a flashing question mark, and never finds a bootable system folder. 

I did find a work around: If I boot off a floppy disk, the SCSI2SD is visible and the PowerBook will boot from it the next time I power on the laptop. 

The whole thing is strange and I have no idea why it’s like this, it was never an issue with the HDD. I’d like to solve this so I don’t have to make sure I bring a bootable floppy with me every time I leave the house with my PowerBook. So if anyone has any ideas, I’m open to suggestions. 

the PowerBook is running Mac OS 7.6.1 and it was a clean install I performed on the 8GB SD card that came with the SCSI2SD. I configured the card to limit the partition size to 1GB.

Ah, beans.

I was kind of hoping it was a SCSI2SD specific issue, since it'd likely either be something I can't do anything about, or requires some changes to the configuration. But if the same thing can happen with regular HDDs, then that opens up more potential causes. One of these days I'm going to try reformatting with a patched version of Apple HD SC and do a clean install to see if that helps. As of right now, the system was formatted with LIDO and restored from a backup-up image from the old drive.

What happens if you remove the battery and power cord for 60sec? My 180c with a SCSI2SD has done this a few times and that's solved it, but I've never had to boot from floppy.
