Filesystems on floppies

[Gareth Barker]

|question: I have a SparcStation 1 with a floppy drive. I want to use
|floppies as small file systems. In the STB of last July there were some
|hints on how to do this:
|
|     mkfs /dev/rfd0c 2844 18 2
|
|and now you should be able to mount it. I don't what I did wrong but this
|doesn't work for me. When I try to mount it on, say, /diskette: 
|
|     mount /dev/fd0c /diskette 
|
|I get the error message:
|
|     mount: /dev/fd0c on /diskette: No such device or address

We had the same problem, and Sun gave us the following mkfs line: 

mkfs /dev/rfd0c 2880 18 2 4096 512 8 5 6

(change 2880 to 1440 for low density).  Notice that you MUST do this
IMMEDIATELY after fdformat - for some reason if you once make a file
system with the wrong parameters you have to re-format before trying
again.  If you don't you get the 'No such device or address' message even
if the mkfs parameters are right.
