580b388917 DISK: Add ATTACH copy option to create a SIMH or VHD copy 
- Fail ATTACH when container type doesn't match drive type and autosizing
  is disabled.
- Be sure to write data at the end of a VHD container right up to the end of
  the disk.

e872682d3c DISK: Major rework to support VHD's with other than 512 byte sectors 
- Added rigorous disk test routine to exercise all supported disk container
  formats with various sector sizes and storage element sizes
- Extended logic to validate disk container simulated device consistency
  with the simulator and/or controller accessing it.

73df9b1c4e PDP10, PDP11, Massbus VAXen, DISK: Rework PDP10 use of sim_disk 
- Make all PDP11, VAX RP and RQ devices autosizing behave similarly
- Generalize the attach help to be specific to the device/system being
   attached
- Remove the sim_disk_pdp10_* calls which weren't correct or needed
   since sim_disk_attach_ex provides sector size which is used correctly

b7824943df DISK: Minimize the sim_disk_pdp10_attach arguments to minimize aguments 
The sim_disk_pdp10_... API's specifically provide 1024 byte sector
interfaces for 64bit data.

Customize the attach help output to be more appropriate for the devices
in the running simulator and the device who's help is being displayed.

6efa9c0a92 PDP10, DISK: Add sim_disk support for PDP10 format disks add to the RP device 
This allows the underlying disk container formats that that sim_disk supports
(VHD, SIMH or RAW) to be accessed from the PDP10 KS10 simulator, and later
on to Rich Cornwell's PDP10-KA, PDP10-KI, and PDP10-KL simulators.

doesn't have DEV_SECTORS set in the DEVICE flags.

Follow on to #768.

6263378df4 DISK: Change auto disk format open logic to include RAW 
Previously auto format detection first attempted a VHD open.  If that
failed, it falls back to a SIMH open which uses C RTL fopen, fread, fwrite
and fclose.  Now a RAW format open is attempted which will often
succeed, not only on CDROM devices, but most normal files can also
be opened in RAW mode which will to direct OS I/O (open, erad, write
and close or CreateFile, ReadFile, WriteFile, CloseHandle).

70d8f759c6 DISK: Fix RAW device (CDROM) access behaviors 
- Only open RAW CDROM devices in read only mode (UNIT_RO) to avoid
   potential write attempts.
- Make sure to properly reopen RAW CDROM devices after media is inserted
   into the drive after an attach thas with no media present OR after an Eject.
