When using a modern IDE drive, the cable has 2 positions (Master and Slave).
You have a choice - you can set BOTH drives to AUTO negotiate; this works most of the time.
However, I prefer to delegate MASTER and SLAVE settings on each drive. This removes any confusion, as they are clearly defined.
You CANNOT have one drive set to AUTO and the other drive set to MASTER or SLAVE. When using AUTO, both drives must be set to AUTO.
Be careful with the “master” and “slave” talk - it’s racist, donchaknow.
I think the new lingo is “community organizer” and “disenfranchised” or is it “union” and “member?”
Couldn't that be construed as racist talk?
