This is perplexing - I am left thinking that there must be some left
over file on your disk that is being mistaken for an FQ table but which
is something else entirely. The problem is that it is on a scratch file
and they are hard to track down since they are deleted as the task dies.
File names are
ttDnnn001,uuu\;
where tt is the file type (FQ) nnn is the slot number in extended hex
and uuu is the user number in extended hex. Try setting BADDISK to
avoid one disk at a time. The problem is aips takes the next available
slot and that slot keeps being available...
Good luck.
