Humm… no.
The letters are assigned in the order the system sees them first, for
whatever reason. The boot disk (puppy) is seen earlier, so it typically
gets the sda letter.
On my machine, I normally boot from sda. However, when I power up the
external drives, they get there first, somehow, and my boot disk gets
labeled sdc or beyond. Worse, the boot disk, lets say the main disk, can
be sda on boot, and sdc after hibernating, because I powered up the
external drives in between. Ie, the names can change during the same
session!! (I’d have to re-verify this someday to be absolutely sure)

I’d have to be there to be sure.

It depends on the motherboard. Mine has three controllers, and I never
know which is which.

Try another plug. All should work. You only need to choose in the Bios
which one to boot first.

Well, yes, you can choose any of them to boot first, but it depends on
the bios (cmos config).

If you have another one available, I would certainly try. Even a
different name.

It is possible to clone one disk to another, byte by byte, if sizes
permit, and the new one will boot - however, some IDs maye have to be
adjusted. And if the second disk is bigger, the partitions have to be
enlarged later (I think gparted can do that).

I’m not sure I understand. :-?

And a good rest.
