Hardly. Sony has no way to know how you might format those disks. FDFORMAT ver 1.8 can get 1.68MB at the same bit density on those same 80 tracks. Norton Backup gets about the same capacity by formatting the data area with 1024-byte sectors instead of 512. The box of disks on my desk right now shows both the unformatted and formatted capacities. It says, "Formats to IBM: 1.44MB." Of course, that's not necessarily true either, as I just pointed out. All 3.5" HD disks will have the identical capacity if formatted the same way. It's not the same situation as with tape, where different lengths can be packaged in the same physical shell.
