The SDC disk driver also supportsthe RX23 floppy disk drive in VAXstation 3100 Model 30 systems.The SDC driver handles the RX33/RX23 disk on drive 2..PPThe RX33 floppy disk drive reads and writes both RX33 and RX50floppy diskettes.  The RX23 floppy disk drive reads and writes highdensity (18 sectors per track) RX23 floppy diskettes and readsdouble density (9 sectors per track) RX23 floppy diskettes..SS "Formatting RX23 Floppy Diskettes (VAXstation 3100 Model 30 Only)"The floppy diskettes used with the RX23 floppy disk drive are not alwayspreformatted.  Although the ULTRIX system does not currently includesupport for online formatting of diskettes, the VAXstation 3100diagnostic \f(CWt 70\fPcommand allows you to format diskettes..PPUse the following steps to format diskettes:.IP 1. 5Shut down the ULTRIX Worksystem Software, and halt the processor..EX# /etc/shutdown \-h +5.EE.IP 2. 5Insert the diskette into the RX23 drive..IP 3. 5Enter the following at the prompt:.EX>>> t 70.EEThe \f(CWt 70\fPcommand begins to prompt you for information.
