I've seen this before. You've got a problem with symbolic links. See this knowledge base article: http://support.microsoft.com/support/kb/articles/Q158/3/62.asp?LN=EN-US&SD=gn&FR=0&qry=disk%20administrator&rnk=44&src=DHCS_MSPSS_gn_SRCH&SPR=NTW40 You might also want to see: http://www.numega.com/drivercentral/tech_tips/symlinks.shtml It might not hurt to download the symlinks.zip file from that page. Incidentally, I don't recommend EVER using disk administrator for the very reason that the results you're seeing are too likely to occur.
