Thanks Jesper for these interesting references. What puzzles me is how this
denial of permission has happened only once on one particular folder that I
created on an external hard drive on a Windows XP computer. I have a brand
new Seagate Freeagent 500 Gig external hard drive, but I think the drive is
working well and was not part of the problem? The fact that I was able to
reperform on my XP computer the job of creating a 100 GIG folder on an
external drive and this second attempt created no problems on my Vista
computer, was a surprise to me because it shows perhaps, that the security
system is not being applied consistently by Vista. Or perhaps I unwittingly
did something different when I recreated the file.
Incidentally, any file that is added to the offending folder, immediately
becomes locked and unable to be read, copied or deleted on my Vista
computer.
Regards, Jim
