Black Box Partition List random garbage

[Fuji-Man]

Hi all,

Every time I boot the black box, the partition list is random data. Clearing the list whacks the boot drive (mydos 4.53/4) somehow. If I manually clear the list, and fix it, next boot list is random again.

Any idea how to fix?

Thanks

I'll try to help out via text, phone, or messages.

Will require some specifics for your drives.

Each are set up differently... make model etc etc

embedded scsi/ or scsi controller etc.

I do have discord channel that I had set up for our users group. https://discord.gg/zupvkPpQ

I have 130xe->bb/fb(180/360/1.44)->SCSI2SD (16gb configured as 4gb)

Drive was formatted with hdinit using 256 byte sectors (16777215 sectors) overnight.

you might need to start the first partition on  higher sector. Your first partition probably overwrites the partition list.

Here some pictures of bb config. Looks like bb is trashing sector 1 with partition list.

The black box partition list takes up 14 sectors.  Your config shows it at sector 16 and your first partition staring on the very next sector.  This is why you are getting it garbled.  Change your partition list to start at sector 1 and it will use sectors up to sector 15 (14 total) leaving sector 16 empty and Your first partition starting at 17

From the BlackBox documentation, Version 1, page 18: "... the partition list starting number must be even."

That sounds right.  So if you start the partion list at 2 there is still 14 available sectors before the start of the first partiton at sector 17.
