Has anyone had any success at all recently in recovering data from
Wabash-branded floppies?
I haven't. The binder on these things has gone to Hades and the
oxide will flake off if you so much as touch it with a drive.
Yesterday, I thought I'd try again after swearing off of the things,
as the disks in question were 10-sector rather than soft-sector. I
wondered if 10-sector being rarer than the soft-sector variety might
not be different.
No soap. That grinding sound, accompanied by dirty heads tells me
that *no* Wabash disk is worth touching.
Anyone got any secrets for these?
Cheers,

Can they be baked to refresh the binder?

Try pulling the media and cleaning it with Weber Costello Markerboard Cleaner,
then let it thoroughly dry.
I am really curious if this works for anyone else. I've tried it a couple of times
and have had some success with batches of media that were complete trash.

Seems to be mostly water (>90 percent) with some PEG and ethylene
glycol added. If the customer insists, I'll give it a try.
But this isn't a simple case of oxide shedding. The damned oxide
doesn't even stick to the substrate. Horrible, horrible stuff.
The web turns up similar experiences:

I wonder if you could pull the media and apply a spray coat
of very fine, very hard lacquer. That might smooth the surface
and hold the oxide in place long enough to get a good read.
Otherwise, I wonder if you could apply that solution that you
used to use with mag tapes. That stuff that makes the flux
transitions visible. Then scan the disk with a high resolution
scanner and see if you could decode the image.

No, my experience of the soft-sector ones was exactly the same, with a
failure rate very near 100%. I got sick of dealing with them and having to
clean drive heads after every single one (and in one memorable case it tore
one of the heads clean out of the drive when it shed its oxide layer). I'm
sure I've complained about them on the list before (and certain Parrot
disks, although those seem to be a bit more of a lottery and don't *always*
cause problems).
