PowerBook 165c & BlueSCSIv2 Drive Mounting Issue

[JDW]

Perhaps @eric or you other BlueSCSIv2 PowerBook edition owners might know, but I'm curious why only one of my two drives (on the SD card) mounts when I power on the machine, despite having a good PRAM battery. I am then forced to use SCSI Probe to mount the second drive, as shown in my short video below.

The BlueSCSI has no influence or knowledge if an image is mounted - MacOS will determine that. BlueSCSI's concern is just the data/block device, and it's up to the OS to use that in whatever way it wants.

Can you open the drives up in DJ and see if they both have SCSI Drivers?

That would require me to disassemble the PowerBook again to access the SD card.

What I did instead was put SCSI Probe into the Control Panels folder, open it, click Options, then tick these two checkboxes:

Upon reboot, both drives mounted just fine. It seems to be a good solution to the problem. I only tested in S7.1, but I suspect it will work in 7.5.5 and 7.6.1 too, which are really the only other version of MacOS I can run on this machine.

It could be that second drive is just a raw HFS volume instead of a device like a real hdd with driver + volume + partition map. It is then "riding" on the first devices SCSI driver and relying on the system init to mount it.

A work around would be to do a partition/format of the device you're having issue with in drive setup or whatever on the vintage mac. that would re-create the partition map/driver/partition (if that is the issue)
