Diskette Hardware Considerations

Keep the following in mind when formatting diskettes:

A Solaris system can format the following diskette types:

On a Solaris system (either SPARC or x86), you can format diskettes with the following densities.

Diskette Size 

Diskette Density 



High density (HD) 

1.44 MB 


Double density (DD) 

720 KB 

By default, the diskette drive formats a diskette to a like density. This default means that a 1.44 MB drive attempts to format a diskette for 1.44 MB, regardless of whether the diskette is, in fact, a 1.44 MB diskette, unless you instruct it otherwise. In other words, a diskette can be formatted to its capacity or lower, and a drive can format to its capacity or lower.
