Hi ! Im from Buenos Aires and "Software del plata" (MS
local tech service) couldn´t help me. I had a serious
problem with my HDD, I recover all files (Best way I can)
but this disk doesn´t boot as primary (I only can use it
as slave), then I install a new HDD as primary with a new
instalation of Windows XP Pro. Then so, I connect the
older HDD as a slave to copy my files, but as I can see I
cannot open any of then at all. Originaly all the files
where encrypted (Green color). I cannot copy from the old
disk to the newest, I cannot gain access to them but I can
see the files and the directories, too. What happend ? How
can I recover 8 GB of my datafiles ? Is there any program
who decrypt with older key in order to use my job ? In
advance, thanks a lot for your help. Stephen
 
You have lost your EFS key. See:

Hi Stephen,

Whatever you do, do not fool with the profile directory of the
account over in the old system. You may even want to make
an NTbackup of it now just to be safe.
You have 8 gigs at stake here.

First, this "Software del plata" does not sound liike Microsoft
support, but rather some tech support partner. If it was actually
MS support then they would (or should) have known that they
can open a support incident with you and recover your EFS key
from the old profile. This is a paid for service, not free.

You most direct and possibly simple solution is to heal the old
system so that you can boot it, log on, and then either transfer
the data out into clear unencrypted for, or export your EFS
key so that you can import it into the new system build.

There is also this alternative if you are technically up to it

Oh yes, another thing is that if you are going to continue use
of EFS you would be well off spending some time digesting these
