A couple of months ago we got a BM5 with a bad HDD up and running again after cloning the HDD (in an external caddy, the BM didn't run on it anymore).

At that time, we just made 2 clones.

Now i have another BM5 with a faulty HDD, and gave it a shot with connecting the -still on the shelf-other cloned HDD.

I was expecting to get messages about wrong HD or something, but no: just starts up and plays just like that.

As i understood, the HDD has a code linked to the Bios chip (like in the BS32000, but...it seems not to matter ?

Anyone knows anything about this ?

I am still going to try to clone the original (faulty) HDD but it also seems to play ok with any other BM5 HDD copy.

It is the serial number that is written to the HDD, if that number does not match the BIOS serial, no SW updates can be done.

Thanks. Off to cloning the original HDD then...

If you have the ServiceTool, it can write the Serial to the existing HDD.

Unfortunately i do not have the service tool.

Is it software which has to be installed on the BM5 ?

No , it’s a service tool on a USB stick which is used to service the BM5 and BS5.

It’s described in the service manual .
