Re: RX02 Difficulties

If you have a system that can create/format SSSD (base RX01 media format) RT11 can reformat that as RX02.  Of the top of my hear the command is INIT and you specify the drive and /double.  It cannot format a blank disk but it can set a RX01 format to double density. Note a RX02 on a PDP-11 will

Re: RX02 Difficulties

Glad to hear that you cleared that up. For the other floppies. 1) DUMP/TERM/RAD50/END:0 DY1: If you share the listing that will give us some hints as to the OS on the floppies. 2) DIR/BAD DY1: will do a bad block scan to see if can read all of the blocks on the media. It

Re: RX02 Difficulties

I just checked all of them in RT-11, out of 12 floppies, two of them were bad, or at least I am unable to perform dir in RT-11. My source of confusion comes from both A) not being able to boot from any of them, and B) not being able to dump them using vtserver. The ones labelled RT-11 don't

Re: RX02 Difficulties

We've gotten around the formatting issue by formatting SSSD using ImageDisk on a regular PC (with a floppy controller that supports single density/FM, of course). If you want RX02 media there's an XXDP routine to upconvert RX01s to RX02s. Thanks, Jonathan On Sat, Dec 16, 2017 at 2:02 PM, Chuck

Well, would you believe it. It was the disks after all. I can't believe they are all bad! Just booted straight into RT-11. Thanks all for your help anyway. Time to play. Aaron. Aaron Jackson via cctalk writes: > Hi everyone, > > I originally posted this on VCFed (which was new to me) but
