I am just wandering, since I haven't read the manual, but is it possible to format a floppy with HPFS on it ? I have tried FORMAT A:/FS:HPFS But it says SYS0530 : You must specify the fixed disk drive So, I am wandering if it is possible. If it is not, why don't IBM let us have it. If we can format a floppy with UNIX (on the NeXT), why can't we do it with OS/2 HPFS. T. Huynh

The only possible advantage with being able to use HPFS for floppies would be to be able to use long file names. The performance issues are completely uninteresting, as a floppy is such a slow media anyway. / Peter -- Peter A. Forsberg Royal Institute of Technology, Stockholm, Sweden.

I have tried It is not possible,. I think That they wanted to keep the Floppies Standard so that you didn't think that the disks are blank and re-format them when you are running DOS. It probably also has something to do with the buffering system for HPFS that makes it work well, and the number of buffers used woud basicly make it read the entore floppy when you first put the disk in and read it. Then you get the fun of dealing with systems that don't properly do the disk change lead thing.

I heard that HPFS is not allowed on any kind of removable media, no matter if floppy, optical disk or whatever. I suppose it is because OS/2 has no equivalent to the mount and u(n)mount commands of unix and therefore must be able to handle unnotified media changes. This enforces write-through caching and a simple filesystem. Gruss, Andreas * Origin: kaiser@ananke.stgt.sub.org - Stuttgart FRG (2:244/7014)
