Telling Master from Slave Hard Drives
I have a Gateway desktop that stopped working. The technician said that the power supply was out and that I needed to go to Windows 11. I told him I would try to replace the power supply - having put together a desktop from parts some years ago. He removed the hard drives saying that it was for their protection while I worked on the power supply. However they are unlike the hard drives I worked with before. No jumpers! And he did not mark them. The power and data connections are also very different now! I wish he had left it all hooked up as is!
If someone could point me to an article on the evolution of power and data connectors, it would be a big help!
All he did was test the power supply. It was arcing! Otherwise he did nothing except to remove the two drives and put them in static free bags. There are the big 24 wire ribbon data connectors which are clearly marked master and slave. but they don't seem to be usable for these drives. It is a much different picture than I had envisioned a month ago when I told him the upgrade to W11 would be unnecessary and too expensive! I just wanted things back to were they were so my wife could get back to her writing - she loves the old keyboard! I can send some pictures.
Did he replace your logic board to a newer SATA board? As there connections are very different than the older IDE/ESDI/PATA parallel connections
It’s been awhile since I worked on an old IDE system. If I remember correctly the very end of the dual connections of the cable is the Master and then the next on in line toward the logic boards connection is the slave and there should be a twist in the cable between. If not the slave needs a jumper.
Please give us your exact model.
Also here’s how to post pictures that show the connections both logic board and drives iFixitでの質問に画像を追加する方法
