In the words of a very wise man, "[...] knowledge is stronger than
memory, and we should not trust the weaker." The VMS FAQ exists to
obviate recollection from a weak memory.

that MicroVAX 3100s have some restrictions on the size of disks
they will boot from.

The size restriction is on the boot disk when the system does a crash
dump. You can normally still boot from larger disks, but your data are
at risk if the system crashes, and the firmware mislocates the dump
file. Perhaps there was a reason that I suggested a 1GB disk, not anything larger.

When I changed the original DEC disk in my Vaxstation 3100 for a later
SCSI one, there was a problem with Tagged Command Queuing which made
the disk periodically thrash itself. I never did investigate it fully,
as the disk did work ok.

One to watch out for if upgrading to a non DEC/larger disk.

Cheers,

Paul.
