Yellow isn't good enough?

[jfoust]

In cases where the plastic disk has broken free from the center hub can be repaired by using a drop of "super glue" on the tip of a needle and place the glue where the metal meets the plastic. However, the index alignment is no longer valid.

Are you saying there's no chance to read the existing data at that point - that my only choice is to reformat, and then the disk could be used?

I tried some gel superglue and it didn't hold. I can try again.
