Seagate st412 and full length xebec controller. Would inserting the cables the wrong way damage the board and drive?
1. Make sure that the ribbon cables are attached correctly to the controller card. For example, sometimes when I do not use my reading glasses, I plug in the cable out by a row of pins - per [here].
2. See [here]. Sometimes, after multiple de-attach/reattach operations, one of the four metal connectors can open up to the point of making a poor connection. Imagine a poor +12V connection between the power supply and the hard drive.
