Wild Guess, here.  If the disk is a double-density disk, your low-density
3 1/2 formatted it low density.  The high density drive looks at the
physical mark (a hole thru the corner) of the diskette and says " Hey,
this is a high-density diskette!  I can't read it!".

Compare a low density floppy with a high density floppy and the physical
differences are obvious.  Maybe if you simply cover the hole on the
low density format diskette, the high-d drive will read it (?).
