They make good >test devices for new versions of BACKUP, VERIFY etc. 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!!! BJS-
