Hi, all
I have recently been amassing Disk ][ drives. I have 4 drives which do not grind (calibrate) I have plugged each of them into 3 separate controller cards, which I am unsure of as well. I've ran a cleaning disk (sealed, NOS) in all of the drives as well.
Can anyone recommend a troubleshooting order of operations?
Should I look at the drives or the controllers?
I am attempting to get them to work with a ][+, are there any quirks to the + that I should be aware of?
Thank You.

do you have any that work? use those to swap out the analog board inside the drive with the ones that you want to test. it should immediately boot from slot 6 on a ][+. this book has a disk ii section which has more info...

Thanks for that link, lots of great information in there. I suppose I should search for and purchase a drive that has been tested to work, at this moment, I don't know if I have a working drive or not... Anyone looking to sell a drive/controller for around $100?

It seems unlikely that you would pick up 4 drives and all would have the same problem. Unless they have been modified the same way. Everyone says 'don't grease the rail' so perhaps if you bought them all from the same place, someone maintained them improperly- by lubricating the rail wrong. Or if they were all stored in a very dirty environment in the same place, it's possible they need to be cleaned on the inside. I've found that direct cleaning of the heads is very important, but probably not the source of your problem.
I definitely understand the desire to get a known tested setup, but if you have time, you may be able to resurrect at least some or all of these drives. People in this group and the Facebook group Apple II Enthusiasts may be helpful if you decide to dive further in and get lost.

True, most are not keyed, but the cable should come out on the side *away*
from the card.
