Hopefully the target directories were (a) empty, or had no conflicting
user number files; and (b) were on a system of the same endian-ism (big or
little; Big includes Sun, IBM, HP and SGI; Little includes Alpha, Intel).

Unless you really need it, zap the message file (MSD*) for that user
number.  It is obviously corrupted, or the wrong endian flavor.  See note
above.  It's likely this is the message file for user #1.  If so:

        cd /the/area/that/corresponds/to/disk_1
        rm MSD001000.001\;

And again, see the caveat above; you can interchange these files
(carefully) between like endian machines, but you cannot cross that
boundary.  There's no way a Linux/Intel system can read any AIPS catalog,
data, or any files other than FITS format from a Sun/Sparc system, for
example.
