AJ,

I wrote down 2 identification numbers of my original Ketron HDD. But none of both match the serial number present on the label sticked on the disk itself.
My issue is : I don't remember how and where I founded them. I believe that one can be translate with the another one. (ASCII - Hexa or something approaching)
Could you contact me by personal email to remind me the process I used.

Thanks in advance.
