From: Johnny Billquist <bqt at softjar.se> But if RT-11 uses this device driver even when reading the disk without trying to handle it as an RT-11 file system, then the RT-11 device driver can't be used at all if you want to read foreign packs. There's a .SPFUN to bypass RT's private bad-block replacement (yes the list is in block 1), so you can easily write a small program to do the copy, but I'm 99% sure COPY/DEVICE will just use .READ so, bad news. Writing a stand-alone program to copy RLs would be straightforward, if you wanted to be done once and for all. John Wilson D Bit
