- Yes! I have a DECUS copy of VDDRIVER and used to use it until my disk space
- bacame 'limited'. Therefore, there were very limited chunks of contiguous
- space left to make the VD disk container file. That problem went away recently
- when I acquired another broken XT2190 with a drive motor. (FOC) Reworked the
- motor and now I have Plenty o' free disks space! ...for a while anyway... ;-)
- The RX23 was also a free-b. So, I figured that this was as good a time as any
- to put it through the ropes.
-
- Also, the pseudodisk (PDA0) could be used for test cases with code munging
- file and volume structures. For those that may not know how: Simply connect
- the driver with SYSGEN and then peruse the STABACKIT.COM file for the little
- macro ditty to configure/size the pseudodrive.
-
- The real issue here -- don't play around on disks with valued data. _IF_ you
- must, be sure your backups are good and current!!!
