DEC (Minc 11?) RX01 disks and PUTR

 I have been asked to see if I can transfer the contents of some 8"
 disks to PC compatible disks. A CP/M disk has offered no challenge,
 but I am stopped dead on a disk whose label indicates that it was
 for use on a DEC Minc 11.
 
 Using PUTR, I have tried mounting the disk as /RX01 and /RT11,
 /FOREIGN, and even /OS8 at separate times. However, whenever I
 invoke the COPY/DEVICE command it selects the disk and errors out
 with the message 'Sector not found reading drive H' 'Abort, Retry,
 Fail?'.
 
 Using AnaDisk, I am able to determine that there are 26x128 byte
 sectors per track, but with a data error message for each sector.
 Considering some of DEC's strange format characteristics I am not
 too surprised that AnaDisk has a problem with it. But PUTR's
 problems do surprise me. Another disk gives exactly the same result.
 It is certainly possible that the disk is simply bad, but could there
 possibly be some other operating system format that is also 26x128
 but does not respond to PUTR and the options that I have tried.
 
 Thanks for any hints that you can offer.
