NEWSWEEP ADVISORY - - - - ALL VERSIONS
---------------------------------------
There is a serious and potentially destructive problem with NewSweep
by Dave Rand when using ZRDOS, ZSDOS, NovaDOS or any other DOS which
does not reconstruct the allocation vector for permanent media with
each disk system reset. This problem occurs when using the Rename
option to reassign a file to another user area. Although the
directory entry for the file will be correct, the allocation vector
for the disk bearing the file will indicate that all blocks of the
"renamed" file are unassigned and any subsequent assignment of blocks
to files may well reallocate portions of the renamed file, destroying
some or all of the data therein.
IF USING ZSDOS, ZRDOS, NOVADOS OR ANY OTHER DOS HAVING A "QUICK" RELOG
FOR PERMANENT MEDIA, NEVER USE THE NEWSWEEP (R)ENAME OPTION TO ASSIGN
A FILE TO ANOTHER USER AREA ON THE DISK ON WHICH IT RESIDES.
