- I don't understand how you can argue that a HD floppy can be formatted as
- 400 K, but not as 800 K? Surely the medium must be of sufficient quality to
- format as 800 K, when it can hold 1.4 M!
- Of course, I'm may be an ignorant fool (happened before), but this "out of
- phase" problem sounds strange.
-
- I actually know people who use HD floppies with the old 800 K drive without
- serious problems.
-
- However, there are two arguments against formatting HD floppies as DD.
- 1. HD is more expensive than DD, and you gain nothing.
- (Not relevant for James Wang in this case.)
-
- 2. If you ever are going to use the DD formatted disk in a SuperDrive, you
- will have some slightly annoying problems, since the drive uses a little
- hole on the floppy to identify it as a HD floppy. I think a piece of tape
- over the hole would ordinarily suffice to solve this problem.
-
- I certainly would be glad to have this phase problem confirmed or denied.
