New drives in the M3100/M76

1. This is early first MR drives and will not work (marble dropping noise) if the too long screws grounds out the disc pack casing. That is reason because of so much insulation tapes wrapped up disc pack itself. 2. They run hot, cool them. Don't take them apart ever. There is few parts that is used once and can't be used again on reassembly. IBM does sells the rebuild kit with new circuit boards and few parts required but cost as much as a new drive itself when new. But this is only temporary solution and somewhat chancy and is last resort to get data off. If anyone happens to have these dead 0661 and 0662's, I'm interested in them for tear-down analysis. IBM does have jumper info on their website for these. :-) Needs to use LLF on any peecee controller or use a desktop or tower IBM ps/2 to convert them to standard 512 per sector type. I have done that once in a while successfully. Cheers! Wizard
