Re: Verbatim? Shudder...
I think 5.25" floppy disk was a flawed media anyway.
You relied on the disk remaining flexible enough to spin in the case which was not flat, stiff enough to not crease while it was being spun up and moved over the heads, and for the glue to remain stable enough to keep the rust particles attached to the disk while it was scoured by the disk head and the 'soft' material on the inside of the case. And you also have the problem of the way that the clamp on the drive grabbed the plastic of the disk itself, and over time damaged the edge of the hole.
From my experience, all 8" and 5.25" floppies ware now of questionable use, regardless of manufacturer. Certainly, I have Verbatim disks that still read, and BASF, Nashua and 3M disks that don't.
The 3.5" and 3" disks were slightly better because at least the case was rigid, and was less likely to rub the surface of the disk while it rotated.
Optical disks are much less likely to suffer, because there is significantly less physical contact (ideally none) anywhere on the disk except where the clamp grabs the disk. I have 30 year old audio CDs that still play, and some CD-R disks that I recorded before the millennium that still can be read.
