No, but it's what (at least some versions of) RSTS's "FIT" utility does when initializing a directory. If you'd be willing to send me a .DSK file, I'd be happy to have a little talk with PUTR. It's lng overdue for an upgrade (and I'm lng overdue for finishing a portable version I started ages ago, as a set of FUSE drivers I was going to roll into a utility that didn't rely on Linux's FUSE and would run anywhere).

Re: DEC RX03 RT11A file extractor
A bit more on the RX03 floppies and why putr probably dies. The home block for these contains the usual "DECRT11A" and "RT11A" tags, as well as the Rad-50 "V3A", cluster size and first directory segment pointer, but everything else in the block is set to ASCII space (hex 20), including the checksum. Is this usual for these floppies? --Chuck
DEC RX03 RT11A file extractor
List: This is the first time I've run across a bunch of double-sided 8" double-density floppies in RX02 encoding. I'm assuming that this is what's known as the RX03. The system is identified on disk as RT11A. Does anyone know of a program to extract the files from images of this sort (1,025,024 bytes: 26x256 sectors/track, 2 sides, 77 tracks)? I've tried John Wilson's PUTR, but it hangs when it sees the image--I can mount the image, but then anything after that just hangs the program. I'd prefer a Linux program, but DOS/Windows would be fine. Otherwise, I'll sharpen my pencil and get coding... Thanks, --Chuck
