80 wire conductor

By jonpgenius ·
I found a missing section on my 80 wire conductor cable that was connected to my 30GB Westerndigita drive. It was wire number 67 from the pin one position on the cable and it had a 3 mm section missing on this single wire. The section in question, is 5 mm form the blue connector itself. At closer examination, under a microscope showed that the wire was cut with some type of tool as it has zagged edges along the sheath of the adjacent wires and the wire stands all chiseled in the same direction at both ends. With all this stated, do you have an opinion on what this would allow the drive to do or not do. Could it bypass say encrypted data or make it compatable with a differant buss technology? Would that missing section allow someone to gain access to just the boot section, like the master boot record? What would be the reasoning for this to be done on a cable?

Any ideas on why this would be will be of benefit as this has me puzzled.

You have a "cable select" style IDE cable.

For this style of cable, you set the drive jumpers to cable select, and the location of the drive on the cable determines which drive is master, and which is slave.

Usually, the connectors are marked as to which is which.

I have noticed several retail packed hard drives having Cable Select cables in the package.

The only thing the cut does is change the IDE "bus "
from Master/Slave to Cable Select.
With cable select which drive is master and which drive is slave is hardwired in the cable.
No controller signals are used.
Everything else works exactly the same.
By the way, the uncut wire sends a ground sigal to the other drive to tell it that it is Master.
This is reversed from the normal sending of 5 Volts as the signal.
