Thanks, Phil. Please PM/email me your address and I’ll arrange to have the “unrecoverable” discs sent to you.
All of the Wabash discs are in the “unrecoverable” group. Most of the Wabash discs haven’t been put into a disc drive by me.
All three of the Micro Power discs, which seem to be official releases, are also in the “unrecoverable” group. One or two of the Micro Power discs have been put into a disc drive by me. There may well be nothing wrong with any of the Micro Power discs — I suspect that the only reason I couldn’t easily archive them is that they’re protected and I’m a dunce at cracking protection. (These aren’t “urgent” because we already have working copies of the games.)
The rest of the “unrecoverable” discs have been put into a disc drive by me: typically I would have kicked off a simple *EXPORT to my DataCentre, the drive would have made some horrible grinding/screeching noises when it tried to read the disc, and I would have immediately cancelled the attempt, removed the disc from the drive, cleaned the drive heads thoroughly, and then moved on to the next disc in the queue.
