For 8" Floppies, used 3M and Dysan (or was it Dyfsan?),
For 5¼" Floppies, used 3M, Imation and Verbatim,
For 3½" Floppies, use/used Verbatim, Imation, Maxell, Sony, and TDK.
Had only a small percentage of bad disks in all three sizes and from all manufacturers.
If a disk comes up with more than 9K bad after a full format (either full format in Windows, or using the DOS command "FORMAT A: /U - the "Unconditional" switch), then the diskette gets tossed in the recycle can.
